Glossary

Every key term, with the chapter that first defines it. Terms are listed alphabetically.

3-2-1 backup — A backup rule: keep at least three copies of your data, on at least two different types of media or devices, with at least one copy kept off-site (physically elsewhere, or in the cloud). Three copies defeats drive failure; two media types defeats a shared failure mode; one off-site copy defeats a local disaster (fire, flood, theft, ransomware).

360 / VR video — Footage captured by a camera or rig that records the entire sphere around a single point at once, so a viewer (usually in a VR headset) can look in any direction — or so a normal flat shot can be "reframed" out of the sphere in post ("overcapture"). Trades the filmmaker's control of framing for immersion; conventional grammar (framing, shot sizes, the cut, the close-up) mostly breaks.

A

A-roll — The main footage the piece is about — the interview, the piece-to-camera, the primary sync-sound action — which carries the words and the spine of the story. The counterpart to B-roll: the A-roll is what the subject says; the B-roll is everything the viewer sees while they say it.

AC (assistant camera) — The crew role that owns focus, the camera's readiness, and the media. The "first AC" (focus puller) keeps the shot sharp and changes lenses; the "second AC" runs the slate and manages/labels the memory cards. The AC exists to prevent the two on-set disasters that cannot be fixed in post: soft focus and lost footage.

Action camera — A tiny, rugged, wide-angle camera built to be mounted on moving things and taken into hostile environments (helmet, chest, handlebar, water). Its defining image — ultra-wide, huge depth of field, heavily stabilized — produces an immersive "you-are-there" look that is a deliberate choice, not a default.

Active listening — The interviewer's discipline of genuinely attending to the current answer (not the next question), following the thread with silence and follow-ups, so the subject opens up and gives the real, specific, self-contained answer.

AGC (automatic gain control) — Automatic level adjustment; turned OFF for dialogue because it raises gain in the pauses, pulling the noise floor up into an audible "pumping" swell.

Agency — A way of working in which you are employed by a company whose business is making video (or marketing) for many outside clients — a production company, creative/advertising agency, or post house — so you serve many clients while the agency finds and bills them and carries the risk; you get salary, variety, and fast learning among professionals, at the cost of autonomy.

AI in video — A fast-growing set of tools that automate or assist individual tasks in the production pipeline — generating images and clips, transcribing, captioning, cutting and reframing, cleaning audio, keying and masking, drafting scripts and shot lists — changing how many steps get done while leaving the decisions about what the video should be (story, taste, intent, responsibility) with a human. Discussed at the level of capabilities and principles, not specific products.

Alpha channel — A fourth per-pixel channel (alongside red, green, blue) that stores transparency/opacity rather than color; what makes layered compositing possible.

Ambience (ambience bed) — A continuous, low background sound establishing where a scene is (café murmur, office hum, park wind); often the recorded room tone, looped and extended. Establishes place, fills the void under clean dialogue, and hides edits.

Animation — Change over time produced by keyframed values — a graphic moving from invisible to visible, off-screen to in place, or small to full size. The "motion" in motion graphics.

Aperture — The adjustable opening (an iris of overlapping blades) inside a lens that controls, at the same time, how much light passes through to the sensor and how much of the scene is in sharp focus. One control, two jobs — which is why it is both an exposure tool (Ch. 5) and a focus/storytelling tool (this chapter).

Archival — Pre-existing material the filmmaker did not shoot — old photographs, film and news footage, documents, home movies, and recordings — used as evidence and texture. It carries authenticity ("this actually happened") but also a creative problem (motion across stills must be motivated), a legal one (rights must be cleared; "old" is not "free"), and an ethical one (it must represent what it actually is).

Archive — The deliberate, long-term preservation of a finished project's essential files after delivery — trimmed of disposable, regenerable files, gathered into one organized package, copied to durable storage, and arranged so the project can be reopened, understood, and even re-edited years later. (Distinct from a backup, which protects active work in the present.)

Audio post (audio post-production) — The whole set of tasks that turn the raw sound on a timeline into a finished soundtrack: organizing and syncing audio, cleaning and leveling dialogue, adding music, sound effects, and ambience, balancing all of it, and mastering the result to a delivery loudness. Begins only after the picture is locked.

B

B-roll — Supplementary footage shot to lay over and around the main footage (the A-roll): the cutaways, inserts, sequences, and atmosphere that show what is being talked about, cover the cuts in the main footage, and give the piece somewhere else to look. In an interview-driven piece it is what makes the interview cuttable at all.

B-roll-driven narrative — A piece whose story is carried by the interview audio (the spine) and told by the B-roll laid over it: the voice leads, unbroken, while the picture roams over the work, the place, and the person — hiding every cut (the L-cut, Ch.28) and showing what the words describe (show-don't-tell, Ch.17). The structural principle of interview-driven documentary, testimonial, brand film, explainer, and oral history.

B-story — A secondary thread that runs alongside the main story (the A-story) and deepens it — usually the personal, emotional, or thematic "why" beneath the surface "what." The A-story informs; the B-story moves; the strongest nonfiction braids them.

Bins — The folders inside an editing project that hold and organize clips (as opposed to folders, the directories on disk where the media physically lives). The name is a holdover from film editing, when trimmed strips of film hung over a cloth-lined bin. Bins hold pointers to media, so a clip can appear in several bins without being copied.

Bit depth — The number of bits used to record each color channel of each pixel, which sets how many distinct tonal steps (from black to white) the file holds per channel: 8-bit = 256 steps, 10-bit = 1,024, 12-bit = 4,096. It is the resolution of tone. More steps means more room to grade before smooth areas (skies, walls, skin) break into visible banding; 8-bit is fine to watch but fragile under a heavy grade, which is why serious grading and Log want 10-bit.

Bitrate — The amount of data a camera records for each second of video, measured in megabits per second (Mb/s). It is the throttle on compression: a higher bitrate keeps more data per second (generally higher quality, larger files), a lower one throws more away (smaller files and, past a point, permanent artifacts like banding, macroblocking, and smearing). Not to be confused with card write speed, quoted in megabytes per second (MB/s); since 8 bits = 1 byte, Mb/s ÷ 8 = MB/s.

Black point — The brightness of the darkest part of the image, set on the waveform (via lift) down to about 0% without crushing shadow detail into the floor.

Blocking — The deliberate arrangement and choreography of where people stand, sit, and move within a scene, and where the camera goes in relation to them, planned together as one decision so that the staging serves the story, lands the subject in the right composition, and hands the edit its coverage. Made concrete with marks (a spot on the floor, a chair, a piece of tape) so a performer lands in frame, in focus, and in the light, take after take. Inherited from the theater (where directors staged actors with wooden blocks); film adds the camera, because staging the people and staging the lens are one act. Blocking determines the 180-degree line (Ch.7) and is what makes matching action (Ch.9) possible.

Board feed — A direct copy of the venue's mixed audio, handed to you from the sound desk (mixing board) as a clean electrical signal, free of room echo, crowd noise, and distance. The single best audio decision at most events, because the venue already placed close mics on the speakers — a board feed borrows those ideal positions ("maximum proximity"). Always paired with a scratch/room-mic backup and monitored on headphones (it fails silently). Ask for a mult/split so your copy doesn't affect the house mix. (Not on any chapter's reserved ledger; introduced fully in 24.6.)

Bokeh — The aesthetic character of the out-of-focus parts of an image (from the Japanese for "blur/haze") — not merely that the background is blurred, but how it blurs: creamy vs. busy, round vs. edgy, smooth vs. nervous. Good bokeh turns background points of light into soft glowing orbs and is a large part of what people call "cinematic."

Boom — The long pole (a boompole) a mic is mounted on so an operator can hold it just out of frame and inches from the action — and, by extension, the technique of "booming" a scene. A shotgun or supercardioid on a boom, angled down at the mouth, is the backbone of professional dialogue: directional (rejects room) + close (great ratio) + out of frame (invisible). Full technique with a partner is Ch.15.

Boom shadow — The telltale bar of shadow a boom pole/mic casts when it crosses a (usually hard) light; killed by working the subject's shadow side, keeping the boom out of the key's throw, angling the pole, or softening the key.

Bounce / reflector — Any surface used to redirect existing light back into the shadows to fill them (additive shaping): white = soft/neutral, silver = brighter/specular/cooler, gold = warm. A fill light you did not plug in — a card, foamcore, a wall, sand, snow.

Brand guidelines — A client's rules for how their brand presents itself: logo usage, exact colors, typefaces, tone of voice, and imagery style, often as a "brand book" or style guide. They are the rails your creativity runs on — a constraint, like the 180° line, that makes the work cohere and stay recognizable. Extract the handful that touch your video (a "brand kit"), and stay on-brand on set (light, palette, wardrobe, movement) as well as in post (grade, titles, music). On-brand-and-competent beats off-brand-and-brilliant.

Budget — The plan for the resources a production will consume, denominated in three currencies — money, time, and favors — listing what the project needs and what each line will cost. Even a zero-dollar shoot has a budget; it is simply paid in hours and goodwill.

Burned-in captions (open captions) — Caption text rendered permanently into the video's pixels — part of the picture, always visible, not toggleable, one language. Used where visibility must be guaranteed: sound-off vertical social and muted-autoplay video.

Buyout — A pricing arrangement in which the client pays (usually more) to own the raw footage and/or project files outright, rather than only licensing the finished video. (§38.2, §38.5)

C

Call sheet — The one-page document issued to everyone on a production (usually the night before) that tells them where to be, when, and what is being shot, plus every vital detail of the day: the location and address, weather and light (sunrise/sunset), the hour-by-hour schedule, the full crew and cast contact list with individual call times, and the address and route to the nearest hospital. The public, everyone-gets-it face of the producer's private schedule.

Call time — The specific time a given person is required to be present, set up, and ready to work — not "heading over," but there and ready. Call times are staggered (crew earlier to build, talent later, catering to match) so the right people arrive at the right moment; there is also a planned wrap time so the crew can pace the day.

Call to action (CTA) — The specific next step a commercial video asks the viewer to take: buy now, book a demo, sign up, visit the site, call, apply, subscribe, learn more. The most important and most often forgotten element of commercial video — the reason it exists. Rules: exactly one CTA (not five); match it to the viewer's funnel stage (awareness → "learn more"; consideration → "see how"; conversion → "buy now"); and deliver it spoken + on-screen + by platform mechanic, front-loaded on short social.

Camera height (eye-level, high angle, low angle) — Where the lens sits relative to the subject's eyes. Eye-level is the neutral, honest default (meets the subject as an equal). A high angle looks down and tends to make a subject smaller, weaker, or observed. A low angle looks up and tends to make a subject bigger, more powerful, or dominant. Height must be motivated by what the scene means.

Career paths (in video production) — The recognizable sequences of roles a person grows through as their skill, judgment, and responsibility increase — from supporting others' work (production assistant), to operating one craft's gear reliably (operator), to authoring a craft's decisions (DP or editor), to being responsible for the whole video (producer/director). Framed as a landscape crossed in many orders, not a fixed ladder — the underlying judgment transfers across roles. (The individual crew roles — DP, gaffer, grip, AC, PA — were first-defined as on-set jobs in Chapter 18 §18.1; Chapter 40 extends them into a career progression.)

CBR / VBR / 2-pass — CBR (constant bitrate) spends the same data every second (simple, wasteful); VBR (variable bitrate) lets data float to the hard parts (better quality per size). VBR is 1-pass (encoder guesses live) or 2-pass (encoder analyzes the whole video first, then spends its budget on the hard parts — better quality at a given size, doubled render time). Used for finals.

Change order — A short written add-on to the SOW describing new (out-of-scope) work, its price, and its effect on the timeline; reframes a new ask from a favor-conflict into a priced choice the client makes. (§38.3)

Chroma subsampling — The practice of recording an image's full brightness (luma) detail but only part of its color (chroma) detail, exploiting the fact that human vision is far sharper at brightness than color. Written as a three-number ratio: 4:4:4 (full color), 4:2:2 (half the horizontal color detail), 4:2:0 (a quarter — color halved horizontally and vertically). Invisible when simply watching; it matters for green-screen keying, heavy color grading, and fine colored detail, where 4:2:0's coarse color gives soft, blocky results.

Client brief — The written statement of what a commercial video is supposed to achieve: the business goal, the audience, the single key message, the call to action, and the constraints (budget, deadline, brand, platform, length, must-includes, approvals). The commercial cousin of the treatment (Ch.16), but oriented around the outcome the client needs rather than the film you want to make. Read a vague one by interviewing the client (Ch.19); always write it back and get it confirmed.

Clipping (audio) — What happens when a signal exceeds 0 dBFS: the recorder cannot represent it, so the top of the waveform is chopped flat into permanent, uncorrectable distortion. The core reason to protect headroom.

Close-up (CU) — A framing that fills the screen with a face (head and shoulders). Its job is emotion — the eyes, the flicker of a decision, the thing not said. The close-up is the visual language's exclamation point; a cut to one is an instruction to the viewer: look here, feel this.

Codec — The compression method (an algorithm) a camera uses to encode video when recording and a computer uses to decode it on playback; the word is short for coder–decoder / compressor–decompressor. It decides how small the file is and how easy it is to edit. Examples: H.264 and H.265 (small, hard-to-edit "delivery" codecs that compress between frames), and Apple ProRes and Avid DNxHR (large, easy-to-edit "editing" codecs that compress each frame on its own). How the picture is packed — distinct from the container that holds it.

Color correction — The technical work of balancing an image to a neutral, accurate, consistent baseline: setting real black and real white, removing any color cast so whites are white and skin looks natural, and matching every shot in a scene. Correction has an objective, scope-verifiable right answer; it comes before grading.

Color grading — The creative stage of color after correction, where you deliberately shape the color and contrast of an image to build mood and give a piece a consistent visual identity. A motivated departure from a neutral baseline, not a fix: correction asks "is it right?", grading asks "what should it feel like?"

color temperature — The warmth or coolness of a light source, expressed in kelvin (K). Counterintuitively, low kelvin numbers are warm (orange; candle ~1900K, tungsten ~3200K) and high numbers are cool (blue; daylight ~5600K, shade ~7500K+).

Compositing — The craft of combining two or more image layers into a single shot so they read as one photographed image.

Constant-quality mode — An export bitrate mode where you name a quality level and let the encoder spend whatever bitrate each moment needs (more on hard frames, less on easy ones); often smartest for one's own uploads. Contrasted with restrict-to-bitrate (naming a target Mb/s), used when a spec dictates a number or a file size.

Container — The video file itself: the wrapper that bundles the compressed video, the audio, and the metadata into one package, identified by the file extension (.MOV, .MP4, .MXF, .MKV, .AVI). The box. Critically, the extension names only the container, not the codec inside — a .MOV can hold H.264 or ProRes or others — which is why "the file won't import" is almost always a codec problem, not a container one.

Content ID — YouTube's automated system that scans uploads against a database of copyrighted music and video and can mute, block, monetize-for-the-owner, or claim a video automatically — even a legitimately licensed one, which is why license records are kept to dispute false claims. Named as the best-known example of platform content-matching. (§38.5)

Continuity — The consistency of every visual and audible detail from shot to shot, so that separately-filmed fragments — shot at different times, from different positions, in different takes — read as one continuous, unbroken event. It has five faces: spatial (geography and screen direction), temporal (action and time moving forward), detail (props, wardrobe, hair, consumables), performance (energy and emotion), and audio (room tone and background). It is a promise the shoot makes to the edit: break it and the cut breaks, and it usually cannot be repaired in post.

Contract — A written agreement, signed by both parties, that sets out what will be delivered, for how much, by when, and on what terms; its real purpose is to make both sides share the same picture of the job so the dispute it would settle never arises. Protects the relationship, not just the maker.

Copyright — The automatic legal right of a creator to control the copying, distribution, and use of their original work (music, footage, images, fonts, graphics, writing). Key facts: it is automatic on creation (no symbol or registration needed to exist); "publicly available" is not "free to use"; and credit is not permission.

Coverage — The complete set of shots of a scene — from enough sizes and angles, with enough overlap — that gives the editor everything needed to assemble the scene and to cut around problems. Coverage is the physical practice of shooting for the edit: gathering the specific pieces the timeline will require.

Creative Commons (CC) — A family of standardized licenses creators voluntarily apply to let others use their work under set conditions — BY (credit), NC (non-commercial only, unusable in client work), SA (share-alike, as this book uses), ND (no derivatives). (§38.5)

Crew roles — The named jobs on a production, each owning a specific department of the work so that no task falls through the cracks and no two people fight over the same decision. On a large shoot each role is a different person; on a small shoot one person wears several hats; on a solo shoot one person does them all, one at a time. The roles do not disappear when the crew shrinks — they collapse onto fewer shoulders.

CRI — Color Rendering Index: a 0–100 score of how accurately a light source renders the colors of objects compared to a reference source of the same color temperature. CRI 90+ is the floor for faces; 95+ is the target. Measures color accuracy, not brightness or warmth; a low-CRI light renders colors badly no matter the grade.

Crop factor — A number describing how much a smaller sensor "crops in" on the scene compared with a full-frame sensor, changing how wide or tight a given lens appears (APS-C ≈ 1.5×, Micro Four Thirds 2×, 1-inch ≈ 2.7×). A 50mm lens on a 2× sensor frames like a 100mm lens on full-frame — the basis of "full-frame-equivalent" focal lengths.

Cross-cutting — Also called parallel editing: intercutting between two or more separate lines of action so the audience understands them as parallel action — happening at the same time — even though the two lines are never in the same shot. The alternation alone creates the simultaneity; shortening the shots as the sequence proceeds quickens the rhythm and builds tension toward a collision or connection.

Crossing the line — Shooting a scene from both sides of the 180-degree line (Ch.7's "line") so that screen direction reverses between shots — a continuity error that flips the geography and disorients the viewer. It reads as a subject suddenly reversing direction or two people who were facing each other appearing to look the same way. Legitimately overcome only by carrying the viewer across: a visibly moving shot, the subject's own turn, a neutral head-on shot, or a cutaway that resets the spatial map.

Cut — The instantaneous join between two shots: the last frame of one followed immediately by the first frame of the next, with nothing in between. Both a noun (the join) and a verb (to make it). The fundamental unit of editing; a well-made cut is invisible because it mimics the natural jump of human attention. The cut is a thought — a decision about where the viewer's mind goes next — not a mechanical splice.

Cutaway — A shot of something other than the main subject or action, still belonging to the world of the piece — a shot the editor can cut away to (the room, a listener, the street, the thing being described, the result). Used to establish, to cover an interview cut, and to compress time. (Points the camera elsewhere.)

Cutting on action — Placing a cut inside a movement — a reach, a turn, a stand, a throw — and continuing that same movement across the cut into the next shot, so the motion carries the viewer's eye over the seam and the cut disappears. Requires the overlap (matching action, Ch.9) to have been shot in each size, and depends on matching the moving thing's position and screen direction across the cut. Its failure mode is the jump cut (cutting on a still frame instead of on motion).

D

Day rate — A fixed price for a day (or half-day) of your time and labor, the unit crew and shooters most commonly quote by; it prices you, usually including your basic kit, with extras (more gear, a second shooter, travel) billed on top. Varies enormously by market, role, experience, and region — no universal figure.

dBFS / clipping / headroom (as used here) — (§14.5) dBFS = decibels relative to full scale (0 dBFS = the digital maximum). Clipping = exceeding 0 dBFS, which chops the peak flat and destroys it permanently. Headroom = the safety gap between normal peaks and 0. dBFS/clipping introduced here for setting gain; "levels/headroom (audio)" is a Ch.15-owned cluster — used lightly here and deepened there.

De-esser — A frequency-specific compressor that clamps down only on harsh, spiky sibilance (roughly 5-8 kHz) when it spikes.

De-hum — A tool that notches out a steady electrical hum at its exact frequency (50/60 Hz) and its harmonics.

De-reverb — A tool that reduces (never fully removes) room echo smeared into a recording.

Deepfake — Synthetic media that replaces or synthesizes a real, identifiable person's likeness or voice so convincingly it can be mistaken for genuine footage.

Deliverable — The finished, exported video file (or set of files) handed to a viewer, platform, or client, cut and formatted to spec.

Deliverable (as used here) — A compressed, platform-matched copy made for a specific destination and meant to be re-made from the master as needed. (Term owned by Ch.1; used, not redefined.)

Delivery bitrate — How much data, in megabits per second (Mb/s), the export spends per second of the finished video — how hard it compresses on the way out. The mirror of Chapter 3's capture bitrate: too low reintroduces banding, blocking, and smearing into the delivered file even when the timeline was clean.

Delivery codec — The codec you encode a finished export into for its destination — the compression scheme applied on the way out, chosen to fit the home rather than the camera. H.264/H.265 to ship to viewers and platforms; ProRes/DNxHR for a master. The capture-side codec families of Chapter 3, turned to face outward.

Demo reel — A short edited montage (typically 60–90 seconds, sometimes as tight as 30) of your strongest shots and moments, cut to music, whose single purpose is to prove quickly what you can do. It is a curated argument, not a complete record — distinct from any single finished video.

Deposit — A portion of the fee paid up front to book the date and begin work; often non-refundable because booking means turning down other work. Paired with releasing the master only on final payment. (§38.2)

Depth of field — The distance range, front to back, in which the image looks acceptably sharp — the zone of focus around the plane you focused on. Shallow depth of field is a thin zone (subject sharp, everything else blurred); deep depth of field is a thick zone (near to far all sharp). Made shallower by three stacking levers: open the aperture, use a longer focal length, and get the subject closer to the lens.

Despill — Removing the green (or blue) light that contaminated the subject's edges from spill, so the edge doesn't glow against the new background; the decisive cleanup step.

Dialogue — The recorded speech of the people in a video (interview answer, piece to camera, delivered line). Usually the most important sound, because it carries literal meaning; viewer tolerance for unclear dialogue is near zero.

Dialogue cleanup — The process of removing everything from a recorded voice that is not the voice — hums, hiss, clicks, thumps, rustle, and room ring — so what remains is intelligible and clean. Reduces problems; cannot resurrect a buried or echo-swamped recording.

diffusion — Any translucent material (tracing paper, a bedsheet, frosted plastic, a dedicated diffusion sheet) placed between a light source and the subject to scatter its rays and enlarge its effective size, making the light softer; the lit surface of the material becomes the new, larger source.

Direct-to-reverberant ratio — (§14.1) The proportion of clean, direct sound (straight from source to mic) to smeared, reflected room sound; excellent up close and terrible far away, which is why closeness beats price. Explanatory concept, not a reserved term.

Directing non-actors — The craft of getting a natural, believable presence from people who are not trained performers (interview subjects, real customers, business owners, experts, yourself) by removing self-consciousness rather than adding technique. The inversion of directing actors: with actors you add (feed intentions and let their craft translate); with non-actors you subtract (get them to stop watching themselves and simply be). Achieved by directing actions and circumstances — never results ("be sad" fails; "tell me about the last time you saw her" works) — and by redirecting the subject's attention outward to a person, a task, or a memory.

Dissolve — A transition (also cross-dissolve / cross-fade) in which one shot fades out as the next fades in, the two overlapping so both are briefly visible together. Signals "time has passed" or "these two things are connected." Requires handles — extra frames beyond the cut point — which only exist if the camera rolled before and after the action. A fade is a dissolve to or from a solid color (usually black).

Documentary — A nonfiction film that shapes real events, people, and places into a story: it presents reality — selected, ordered, and framed on purpose — rather than staging or inventing it. Grierson's phrase, "the creative treatment of actuality," still summarizes the genre's central tension (creative and actual).

Double-system sound — Recording the picture on the camera and the audio on a separate device (a recorder, mixer, or second phone), to be married to the picture in the edit; contrasted with single-system sound. Chosen for cleaner preamps, mic independence, and redundancy.

DP (director of photography / cinematographer) — The crew role that owns the image: the camera, the lens, exposure, framing, and the lighting plan. Translates the director's intent ("this should feel warm and hopeful") into concrete lens, aperture, and lighting decisions. On a small crew the DP is also the camera operator.

Drift (sync) — The gradual loss of sync over a long take when the camera's and recorder's clocks run at slightly different speeds; perfectly aligned at the clap, visibly off by the end. Fixed by re-clapping/syncing in shorter chunks, or by shared timecode.

Drone / UAV — A remotely piloted flying camera platform (an unmanned aerial vehicle), usually a small multi-rotor aircraft carrying a stabilized camera on a gimbal. Legally it is an aircraft operating in shared airspace, not a camera accessory — which is why it carries registration, licensing, airspace, line-of-sight, and safety obligations that vary by jurisdiction and must be checked with the local civil-aviation authority before every flight.

Ducking — Automatically or manually lowering the music (or another bed) a few dB under each line of dialogue and lifting it back in the gaps, so the voice stays clear.

Dynamic range — The span between the darkest and brightest parts of a scene a camera can capture in a single exposure while still holding real detail at both ends, measured in stops (each stop is a doubling or halving of light). Many real scenes (a person against a bright window) contain more range than a camera's roughly 12–15 stops can hold, forcing a choice of which end to protect; a Log profile or a wider-range camera holds more of both.

E

Encoder — The software or hardware that compresses a program feed into a stream small enough to send over the internet, using a delivery codec (H.264/H.265) at a chosen bitrate. The link where bitrate is set; too high for your upload and the stream stutters. (Introduced 24.4; delivery codecs owned by Ch.3/Ch.36.)

EQ (equalization) — The tool that raises or lowers specific frequency bands of a sound to shape its tone: rolling off low rumble, cutting the "mud" in the low-mids, boosting the "presence" that makes a voice intelligible, adding "air" up top. Worked subtractive-first (cut problems before boosting good parts).

Event coverage — The craft of capturing a real, unrepeatable event — a wedding, ceremony, conference, concert, graduation, or live broadcast — as it actually unfolds, with no ability to stop it, re-stage it, or ask for another take. The subject is reality on its own schedule; the job is to be positioned, exposed, focused, rolling, and recording clean sound before each moment arrives. Built on three pillars: a run-of-show, redundancy, and "roll early, stop late, never chase."

Export / render — Performing every instruction in a finished timeline — edits, color, titles, and mix — and writing the result as one new, self-contained video file that plays anywhere, without the project's original clips or software. "Render" emphasizes the frame-by-frame work; "export" emphasizes the file leaving the project. The same button.

Exposure — The overall brightness of the image: how much light the camera collected and how strongly it amplified that light. An image can be underexposed (too dark, shadows collapsing to black), overexposed (too bright, highlights burning to white), or correctly exposed for the story.

Exposure triangle (video) — The classic ISO/aperture/shutter relationship, but with the shutter pinned by the 180° rule (Ch.2). Because the shutter is spoken for, video exposure is balanced with ISO, aperture, and a fourth control the video shooter adds — the ND filter. A relationship diagram of trade-offs, never an equation.

Eyeline — The direction a subject is looking, and, in coverage, the imaginary line from their eyes to whatever (or whoever) they are looking at off-screen. A matched eyeline — the two subjects' looks opposite, crossing at consistent heights, aimed where the other person really is — fuses two separately-filmed shots into one conversation.

Eyeline direction — The deliberate control of where a person looks — to the lens (direct address: the viewer is being spoken to; host/vlog/testimonial), off the lens (to an interviewer beside the camera: the "overheard" documentary look; Ch.19), or into the scene (a character unaware of us; the Café reaction) — chosen for the relationship it creates with the viewer and matched across shots for continuity. Builds directly on the eyeline (Ch.7 §7.4) and eyeline continuity (Ch.9 §9.5); includes controlling lens height, which sets the power reading (Ch.7 §7.2). Directed by giving the eyes a specific, real target to rest on — never "look over there."

F

f-stop — A number expressing the aperture size as a ratio of focal length to the width of the opening (f/1.8, f/2.8, f/8), in which — counterintuitively — a smaller number means a bigger opening and more light. Each full stop halves or doubles the light of the neighbouring one; the exposure meaning of "a stop" is developed in Ch. 5.

Fair use / fair dealing — A narrow, fact-specific, jurisdiction-dependent exception allowing limited use of copyrighted work for purposes like criticism, commentary, news, or parody; a case-by-case defense, not a reliable blanket permission — especially risky for commercial work. (§38.5)

False color — An exposure overlay that recolors the entire image according to brightness, mapping each brightness level to a specific color so the frame becomes a heat-map of exposure. Best for placing skin precisely. The palette is not standardized, so the shooter must learn their own camera's key colors (clipping, correct skin, noise floor).

Feature vs. benefit — A feature is a fact about a product ("stainless steel, 500ml"); a benefit is what that fact gives the viewer ("hot coffee at 3pm"). Commercial video should show the benefit — "sell the hole, not the drill" (§22.4).

File naming — A deliberate, consistent scheme for naming files, clips, and folders so that each asset's identity — the project, the date, its source, its content, and its version — is legible from the name alone and sorts correctly on any machine.

Fill light — A secondary, softer, lower-intensity source (or a bounce/reflector) placed opposite the key that raises the brightness of the shadow side to control contrast — how deep the shadows go. A good fill lifts the existing shadow without creating a second, competing set of shadows. The key-to-fill difference is measured in stops (≈2 stops under = the standard flattering interview look).

Flag — Any opaque, dark surface used to block or cut light off part of a scene; placed against a subject's shadow side it becomes negative fill. (Introduced in Ch.13 §13.5; not a reserved ledger term.)

Flesh-tone line — The vectorscope reference (older gear labels it the "I-line") running from the center outward toward roughly the 11 o'clock position, between the red and yellow targets and closer to red. Correctly balanced human skin of every complexion falls along it; complexions differ in saturation (distance out along the line) and luma, not in the angle.

Focal length — The property of a lens, measured in millimetres, that determines how much of the scene it takes in and how large distant objects appear — in short, how "wide" or "telephoto" the lens is. A small number (16mm) is wide and takes in a broad angle; a large number (200mm) is long and magnifies a narrow slice. Because sensor size changes what a given millimetre number frames, this book quotes focal lengths as full-frame-equivalent when it matters (see crop factor, Ch. 2).

Focus pull (rack focus) — The act of changing focus during a shot, shifting the sharp plane from one subject to another while the camera rolls, so the viewer's eye is led from the first to the second. "A cut you don't have to make." On a film set it is important enough to be a dedicated job — the first assistant camera, or "focus puller."

Folder structure (project-wide) — The complete, top-level organization of all of a project's assets — media, project files, documents, exports, deliverables, and the eventual archive — arranged in one consistent shape that is reused identically for every job, from the brief to the archive. (Extends the edit-only folder tree of Chapter 27 §27.2 to the whole life of a project.)

Foley — Everyday human sounds (footsteps, cloth movement, handling) performed and recorded in sync to picture; a subset of spot effects.

Footage — Raw, unarranged shots straight off the camera; the potential material from which a video is edited.

FPV — First-person view: a style of drone flying (and a class of drone built for it) in which the pilot wears goggles showing the camera's live feed and flies as if riding inside the aircraft, capturing fast, fluid, acrobatic shots that fly through spaces. High skill and crash risk; carries every legal duty of ordinary drone flight and often more, because flying through spaces at speed frequently breaks the visual-line-of-sight requirement many jurisdictions impose.

Frame rate (fps) — How many still frames the camera captures each second (24, 30, 60 fps). It determines the feel of motion — 24 fps reads as cinematic, 60 fps as smooth and "live" — rather than the "quality" of the image.

Frankenbite — (industry/reality-TV slang) A soundbite stitched together from words a person said at different times, to make them appear to say a sentence they never actually said. The canonical example of fabrication built entirely from "real" fragments — dishonest because meaning lives in arrangement.

Freelance — A way of working in which you sell your skill and time job to job, as an independent business, to many clients — finding your own work, setting your own rates (Chapter 38), and carrying your own risk, gear, and dry spells in exchange for freedom and variety.

G

Gaffer — The chief lighting technician; the crew role that owns the practical execution of the DP's lighting plan and the safe running of power. Places, powers, and shapes the lights so the image looks the way the DP wants. Rule of thumb: if it makes light, it's the gaffer's.

Gain — The amount by which a recorder or camera amplifies the weak incoming microphone signal to a usable recording level, set manually before recording. Too low → you boost it in post and raise the hidden hiss (noise floor); too high → the signal clips at 0 dBFS and distorts permanently. Set so dialogue peaks around -12 dBFS with headroom below 0.

gel — A thin, colored, translucent sheet placed in front of a light to change the color of its output — either a correction gel (e.g. CTO, CTB, minus-green) to make mismatched sources match, or a creative gel to add a saturated, motivated color.

Generation loss — The compounding, permanent quality damage from encoding an already-encoded (lossy) file: a lossy encoder cannot distinguish real detail from prior-encode damage, so each re-compression loses again and adds new artifacts. Caused by deriving one deliverable from another (e.g. the vertical cut from the finished horizontal file); avoided by deriving every deliverable from a near-lossless master or the timeline.

Getting hired — The craft of converting attention into paid work: being found (presence), proving you are good (the reel and portfolio), and making it easy to say yes (a fast, clear, low-friction conversation). Most work comes from relationships and referrals rather than cold applications.

Gimbal — A motorized stabilizer that uses motors and motion sensors to hold the camera level and steady, isolating it from the operator's footsteps so the camera appears to float through space. Reads as smooth, elegant, controlled, dreamlike. The affordable modern descendant of the Steadicam, a body-mounted mechanical stabilizing rig (widely credited to inventor Garrett Brown). Must be physically balanced before it is powered on.

Golden hour — The roughly one hour after sunrise and one hour before sunset when the low sun gives warm (~3000–4000K), soft-edged, directional light — the most flattering natural light for faces and landscapes; loosely extended (as "magic hour") to the brief glow just after the sun drops below the horizon.

Graphic match — A match cut in which the shapes of the two shots line up (a circle becomes a circle, a horizon becomes a horizon), so the eye, locked on the form in the first shot, glides across the cut to find the same form in the second. The most literal kind of match cut.

Green screen (chroma key) — A solid, evenly-lit colored backdrop (usually green, sometimes blue) shot behind a subject so its color can be identified and made transparent in post. "Chroma key" is the technique of keying on that color.

Grip — The crew role that owns everything the camera and lights sit on, move on, or are shaped/blocked by — the rigging and support (tripods, dollies, sliders, stands, flags, sandbags). Works closely with the gaffer; rule of thumb: if it shapes, blocks, or rigs, it's the grip's.

H

Handheld — The camera held in the hands or braced against the body with no mechanical stabilizer, so it carries the natural micro-motion of a human holding it. Reads as immediate, raw, subjective, urgent, present — the language of documentary and of "you are here." The instability is expressive content, not a flaw; the operator chooses how much energy it has.

Handheld mic — (§14.2) A rugged visible "stick" mic held at the mouth (reporting, hosting, stages, vox pops). Named in the outline's §14.2 but not a reserved ledger term.

Hard light — Light from a source that is small or far away relative to the subject; its near-parallel rays produce crisp, sharply defined shadow edges and high contrast. Examples: direct midday sun, a bare bulb, a phone LED. Dramatic and unforgiving.

Hardware encoder — A dedicated chip (in many CPUs/GPUs) that encodes H.264/H.265 far faster than software; a menu choice that speeds up rendering without changing the delivered file's essential quality — a time saving, not a purchase.

Headroom — The space between the top of a subject's head and the top edge of the frame. Too much (a wide band of empty ceiling) is the most common beginner error; too little crops the skull. The professional's rule that replaces it as shots tighten: put the eyes on the upper-third line and let headroom fall out naturally.

Headroom (audio) — The gap, measured in dB, between the loudest recorded peaks and the 0 dBFS ceiling — the safety margin that keeps an unexpected loud moment from clipping. Location dialogue keeps roughly 6–12 dB.

High-pass filter (low-cut) — A switch on many mics/recorders that rolls off very low frequencies (typically below ~80 Hz), where rumble and handling noise live but the voice mostly does not; turned off if it thins a deep voice.

High-speed / slow motion — Footage captured at a high frame rate and played back at a normal frame rate, so motion expands into slow motion (slow factor = capture fps ÷ playback fps; e.g. 120 fps → 5× slow at 24 fps). Reveals what's too fast to see, confers emphasis and grace. Hungry for light (each frame gets a shorter exposure), and deliberately uses a fast shutter — the one place the 180° rule is abandoned on purpose.

Hyperlapse — A moving timelapse: the camera itself travels a set distance between each captured frame, so the finished clip flies through space and time at once (teleporting down a street, up a stairs). The moving cousin of the static timelapse; framed by choosing a fixed target point and keeping it centered as the camera moves. Effectively the walk-and-talk (Ch.8) executed one frame at a time.

I

In-house — A way of working in which you are employed by a single organization to make its video, doing everything from planning to delivery for that one "client" (your employer) in exchange for a steady salary and deep knowledge of one brand, at the cost of variety and creative control.

Ingest — Getting your footage and audio off the cards and into your editing project — copied, verified, and imported — so it is organized and ready to cut. Has two halves: the offload (the physical copy from card to drive) and the import (bringing the copied media into the editing software). The offload comes first; it protects the footage.

Insert — A close-up shot of a specific detail within the main action, inserted into it (the hands on the tool, the finger on the button, the cup on the saucer, the phone screen). Shows the thing too small to read in the wider shot and gives the editor a place to hide a trim. (Points the camera closer.)

Integrated loudness — The average loudness over an entire program; the number you master to. Contrasted with momentary (~0.4 s) and short-term (~3 s) windows.

ISO — How much the camera amplifies the signal captured off the sensor before writing the image. Higher ISO makes the picture brighter but also amplifies noise; it does not collect more light. Measured in whole numbers (ISO 100, 800, 3200), each doubling being one stop.

ISO (isolated) recording — Each individual camera's own full-length angle, recorded to its own card independent of any live cut. Recording every ISO under a live switch is what makes a missed live cut recoverable in post — you still have every angle in full. (Introduced 24.3.)

J

J-cut — A split edit in which the sound of the next shot begins before its picture — you hear the incoming scene while still seeing the outgoing one. Named for the rough letter J the audio and video blocks trace on the timeline (the incoming audio reaches back under the outgoing picture). Used to enter a new place, scene, or speaker so the change feels inevitable rather than abrupt, because the ear leads the eye in.

Jump cut — A cut between two shots of the same subject that are so similar in size and angle that the subject appears to "jump" abruptly within the frame rather than being seen from a genuinely new view. It arises from cutting time out of a single static framing, or from coverage shots that are too alike. It is an error when accidental in a scene pretending to be continuous, and a legitimate device when deliberate and consistent — the native grammar of vlogs and talking-heads, and a stylistic rupture in narrative film (see Breathless, 1960). Intent and consistency decide which it is.

K

Ken Burns effect — A slow, motivated push-in or drift across a still photograph to give a flat image motion and time; named for filmmaker Ken Burns, who used it distinctively (e.g. The Civil War, 1990). Ethical/craft rules: move only toward a story-relevant point, vary the moves, and scan stills well above delivery resolution.

Key light — The primary, dominant light source in a setup; it establishes both the subject's exposure and the direction the light comes from. Every other light is placed in relationship to the key. Its position — horizontal angle (≈45° off the lens axis is the flattering default) and height (slightly above the eyeline, angled down) — is a storytelling decision, not a fixed rule.

Keyframe — A marked point in time where a property's value (position, scale, opacity, rotation) is set and pinned; the software calculates the frames between two keyframes automatically (interpolation). Two keyframes with different values make a move.

Keyframe interval / RTMP / SRT — Streaming technicals (24.4, 🔬 The Tech box): the keyframe interval is how often the codec sends a full anchor frame (live platforms commonly want one every ~2 s); RTMP is the long-standing common ingest protocol; SRT is a newer protocol built to survive unreliable connections. Recorded here as inline technical vocabulary, not reserved terms.

Keying — The post-production process of generating a matte from footage — most often by selecting the chroma-key color and making it transparent — and refining the matte until the subject's edges are clean.

Kill fee / cancellation fee — What the client owes if they pull out after booking (having caused you to turn down other work for the date). (§38.2)

Kinetic type — Text that moves and changes in time as the designed element itself, rather than as a label on top of footage — words that appear, scale, and slide, synchronized to speech or a musical beat so the typography becomes the picture.

L

L-cut — A split edit in which the sound of the current shot continues after its picture ends — you keep hearing this scene while already seeing the next. Named for the letter L the blocks trace (the outgoing audio extends forward under the incoming picture). The most common professional cut in nonfiction: it is what lets B-roll or a cutaway lay over a continuing voice, hiding the picture cut under the unbroken sound.

Lavalier (lav) — A tiny clip-on microphone worn on the person, typically 6–8 inches below the chin on the sternum, so it stays close to the mouth regardless of camera position. Usually omnidirectional. Comes wired (cheap, reliable, tethered) or wireless (a body-worn transmitter to a receiver on the camera — buys movement, not better sound). The phone-first shooter's highest-return tool.

Lead room — The space left in front of a moving subject, in the direction of travel, so they move into the frame rather than off its leading edge. On a moving shot it must be actively maintained as the subject travels (see Ch.8).

Leading lines — Lines within the frame — real (a road, a rail, a counter edge, a hallway) or implied (the direction of a gaze) — that draw the viewer's eye along them, usually toward the subject or into the depth of the shot. Perspective makes parallel receding lines converge, turning them into powerful arrows; aim that convergence at the subject with your feet.

LED panel — A flat array of light-emitting diodes used as a video light; the modern low-budget default because it is dimmable, often bi-color (adjustable kelvin) or RGB (any color), cool-running (safe to gel), and frequently battery-capable.

Levels — How loud a recorded audio signal is, read on a meter in dBFS (decibels relative to full scale), where 0 dBFS is the absolute digital ceiling; location dialogue is aimed to average around −12 dBFS.

Licensing — Obtaining permission — a license — to use someone else's copyrighted work under stated terms, usually for money or under conditions; a license is permission to use, not ownership. The terms that matter: what use, where, how long, how many projects, and whether attribution is required.

lighting ratio — The difference in brightness between the key-lit (bright) side of a subject and the fill/shadow side, expressed in stops or as a ratio (1 stop ≈ 2:1, 2 stops ≈ 4:1, 3 stops ≈ 8:1). The primary control for mood: low ratio = high-key/open, high ratio = low-key/dramatic.

Live streaming — Broadcasting video and audio in real time over the internet to viewers who watch it as it happens, with no edit between the camera and their screen. Raises the stakes of event work one more notch: no second take and no edit — whatever leaves the switcher goes straight to the audience. Its whole discipline is the signal chain (cameras → switcher → encoder → upload → platform → viewer) and its weak links (upload speed, bitrate) — plus one rule: always record the program locally too.

Location sound — The craft of capturing usable audio in real, uncontrolled spaces (rooms, cafés, streets, events) as opposed to a treated studio — managing the world's noise and reverberation rather than eliminating it, through proximity, absorption, rejection, and timing.

Locked-off — Working term for a static shot: the camera perfectly still, mounted on a tripod (its legs are "sticks"), with the pan and tilt tightened so nothing moves. The strong default of the craft — it reads as stable, objective, and calm, and lets the performance and composition carry the frame. A still camera is not a still frame: movement within the frame keeps a locked-off shot alive.

Log — Short for logarithmic; a picture-profile recording curve that stores the sensor's full captured range as a deliberately flat, low-contrast, desaturated image, distributing tones logarithmically so that far more of the camera's stops (especially highlights and shadows) survive into the file. Log is not a look but an information container designed to be graded: ungraded, it looks grey and "wrong" on purpose. It must be graded, wants 10-bit (8-bit Log bands badly), and needs careful, slightly-bright exposure to keep shadow noise down.

Long-GOP — (Concept from Ch.3; named here for the proxy rationale.) A codec that stores mostly the differences between frames, so displaying one frame requires decoding a group of surrounding frames — space-efficient but hard to scrub. Contrasted with all-intra (intraframe), which stores every frame whole (bigger files, effortless playback). A proxy is essentially a small all-intra copy.

Loudness — How loud a program feels to a listener over its whole duration — its sustained perceived level, not its momentary peaks — measured in LUFS.

Loudness range (LRA) — A measure of how much a program's loudness varies across its duration; large = big dynamics, small = consistent loudness.

Lower third — A graphic in the lower portion of the frame that identifies a speaker or subject — typically a name line and a smaller role line — laid over the picture without blocking the face. Also called a name super (superimposed name).

LUFS (Loudness Units relative to Full Scale) — The unit of perceived loudness, weighted to match human hearing across frequencies; the scale you master a finished program to (e.g. about -14 LUFS for streaming). Distinct from dBFS, which measures instantaneous peaks. (LKFS is the same measurement under another name, used in North American broadcast.)

LUFS mastering — The final audio-post step: adjusting the entire mix so its integrated (whole-program) loudness hits the destination platform's target while keeping true peaks below a safe ceiling (typically -1 dBFS). You master to the target, not past it, because platforms normalize loudness.

LUT (Look-Up Table) — A preset that maps every input color to a fixed output color in one blind step. Technical/conversion LUTs perform a standardized transform (e.g., Log→Rec.709) and belong in correction/output; creative/look LUTs impose a saved style and belong after correction, on their own node, at reduced strength — a starting point, never a grade by itself, and never anything selective.

M

M&E (music-and-effects) version — A deliverable of the full mix minus the dialogue, so a piece can be re-voiced in another language.

Mask — A shape drawn to isolate a region of the frame, to include or exclude it (a garbage matte is a mask; a power window from Ch.32 is the same idea).

Master (delivery master) — The single highest-quality, self-contained export of a finished piece — full resolution and frame rate, least compression affordable (typically ProRes 422 HQ or DNxHR HQX in a .mov) — kept and archived as the authoritative copy, and the source from which every deliverable is derived. Kept clean (no burned-in captions). Distinct from the project file: a master is one flat video with no software dependencies. (Paired with Chapter 1's deliverable, which is not redefined here.)

Master shot — A wide take that runs the entire scene from start to finish in one continuous take, capturing all the action and dialogue. It is the spine and safety net of the master-and-coverage method: shoot the master first, then re-shoot the scene for the tighter sizes, each pass overlapping the full action.

Match cut — A cut between two shots deliberately joined by a strong shared link — a shape, a composition, a movement, or an idea — so that the first image seems to become the second and the join produces a meaning neither shot holds alone. Meant to be felt, not hidden; used rarely, only when the two things truly are connected. Its most literal form is the graphic match (a shared shape); its deeper form matches two shots on a shared idea (e.g., 2001's bone → craft).

Matching action — The practice of shooting the same physical action more than once, across different sizes or angles, performed the same way each time and with enough of the movement repeated in each shot (overlap) that the two versions can be joined mid-motion in the edit. It is the shooting half of the edit's "cutting on action" (Ch.28): because motion draws the eye and briefly blinds it to the cut, a cut placed on a matched movement is invisible. Requires consistent pace, specifics, start/end marks, overlap, and screen direction.

Matching shots — Making every shot in a scene share one consistent color and tone so cutting between them is invisible and the scene reads as one continuous place and time. The method: pick a hero shot, then match every other shot's tone, then color, then skin to it.

Matte — The alpha channel viewed as a black-and-white image: white = fully opaque (keep the foreground), black = fully transparent (show the background), grey = partial transparency (soft edges — hair, motion blur, glass).

Media management — The discipline of keeping every asset in a project — footage, audio, music, graphics, project files, and exports — organized, findable, and safe, from the first offload all the way to the final archive. Runs on two mirrored layers: folders on disk and bins in the project.

Medium shot (MS) — A framing of a person roughly from the waist up: the conversational default, close enough to read expression and wide enough to see gesture and posture. Much dialogue lives here.

Microphone — A device (a transducer) that converts the pressure changes of a sound wave reaching one point in space into a matching electrical signal a camera or recorder can store. Because it captures only the sound that reaches it — voice, room echo, and noise baked together and unseparable — where you place it and which way it faces decide the result far more than its price.

Mixed light — A scene lit by two or more sources of different color temperature at once (classically cool daylight plus warm tungsten/LED practicals), which no single white-balance setting can neutralize. Handle by killing one source, matching them (gels/re-bulb), embracing it (balance for the key, let practicals glow), or correcting in post.

Model release — A signed document in which a person who appears identifiably in a video grants the producer permission to use their image, likeness, and voice for stated purposes; the paper that converts footage of a person into footage you can legally publish, sell, or advertise with. A parent/legal guardian must sign for a minor.

modifier — Anything attached to or placed in front of a light to change the quality, shape, spread, or intensity of its output — diffusion frames, softboxes, umbrellas, grids, barn doors, snoots, and reflectors are all modifiers.

Monitoring — Actively listening to the recorded signal — the actual output of the recorder or camera, through closed-back headphones — while recording, so you hear what is being captured to the file (including faults a level meter cannot show) rather than what the room sounds like to the naked ear.

Montage — A sequence of short, chosen shots — usually carried by one continuous piece of music rather than dialogue — that compresses time and conveys a process, a change, or a mood by showing a series of representative moments instead of a continuous scene. Its craft is selection and ellipsis: each shot shows a different stage of a change, and the viewer reads the difference between shots as elapsed time. (Distinct from the broad theoretical sense of "montage" = the idea that meaning is created by joining shots.)

Mood (in color) — The emotional temperature a color treatment creates (warm/inviting, cool/isolating, desaturated/bleak, rich/nostalgic) — the feeling color puts under a scene before anything is said. The color-stage extension of the lighting mood introduced in Chapter 12.

Motion graphics — Designed, moving graphic elements — text, shapes, logos, and simple illustrations — added on top of a video to deliver information, brand it, and guide the viewer's eye. They form an information layer over the picture, never a replacement for it.

Motivated light — Lighting arranged so that every source appears to come from a believable origin within the scene (a window, a lamp, a screen, the sun), even though the actual instrument is hidden. The opposite, unmotivated light, comes from nowhere in the frame and reads as artificial or "TV-lit." The lighting cousin of motivated movement (Ch.8).

Motivated movement — A camera move the audience feels a reason for: it follows a subject, reveals new information, redirects attention, or matches an emotional beat. Its opposite is arbitrary movement, which drifts for no reason the viewer shares and so calls attention to itself as camerawork. Motivation is the line between a look and an accident, and the governing rule of the chapter: if you can't say what a move is for, don't make it.

Multicamera — Capturing the same event or subject with two or more cameras running simultaneously from different angles, so a single continuous, unrepeatable moment can be cut between angles — in the edit or live on a switcher. The defining technique of event work: if one camera always holds a clean safe frame, the others are free to reframe and hunt reactions, and every angle is the same moment seen from another place. Also called "multicam."

Murch's Rule of Six — Walter Murch's ranked list (from In the Blink of an Eye) of the six things a cut can serve, in order of importance with the weights he assigns: emotion (51%), story (23%), rhythm (10%), eye-trace (7%), the two-dimensional plane of the screen / screen direction (5%), and the three-dimensional space of the action (4%). When a cut cannot satisfy all six, protect the top and sacrifice from the bottom; emotion alone (51%) outweighs the other five combined.

Music bed — A piece of music laid underneath the dialogue and picture to set mood, energy, and pace — sitting low in the mix and ducking under the voice, supporting the scene rather than competing with it. Must be properly licensed.

N

Narrative arc — The line of meaningful change a story travels from beginning to end, such that something is different at the finish than at the start (a person, a situation, or the viewer's own understanding). If nothing changes, there is no story.

Native ISO (base ISO) — The specific ISO at which a sensor performs best, delivering its cleanest image and widest dynamic range. It is not always the lowest number on the dial (many cinema cameras base at ISO 800); some cameras have two (dual native ISO).

ND filter — A "neutral-density" filter: dark glass placed in front of the lens that removes light evenly across all colors, without changing color, motion, or focus. It is the video shooter's essential tool because, with the shutter pinned by the 180° rule, ND is the only way to darken a bright scene while keeping the chosen shutter and aperture. Rated in stops removed (ND8 = 3 stops; ND64 = 6 stops).

Negative fill — The subtractive technique of placing a dark, opaque surface near the shadow side of a subject to absorb ambient light, deepening that shadow and restoring contrast and shape; the outdoor fix for light that is too flat. (Introduced in Ch.13 §13.5; not a reserved ledger term.)

Negative space — The deliberate empty or unoccupied area of the frame around the subject. Used on purpose it isolates a subject, sets mood (solitude, scale, calm), creates tension and anticipation, and — critically for video — reserves the clean area where titles, lower thirds, and captions will live in the edit.

Net terms (net-15 / net-30) — Payment due within 15 or 30 days of the invoice; standard invoice terminology. (§38.6)

Niche — The specific, narrow kind of work you are known for and choose to pursue — defined by subject, client type, format, or a combination. Narrowing a niche tends to widen opportunity, because the specialist is the obvious, lower-risk call for their one thing.

NLE (non-linear editor) — The software you edit in: a program that lets you arrange clips in any order and freely rearrange, trim, or replace them without redoing everything downstream. "Non-linear" (versus the old tape-to-tape method of building strictly front to back) is what makes trying things — and therefore real storytelling — free.

Node — One self-contained, reversible step in a grade: a single adjustment that takes the image, changes it, and passes it to the next step. DaVinci Resolve arranges nodes in a node tree; layer-based tools (Lumetri, Final Cut, etc.) stack the same idea as adjustment layers. The universal principle: build a grade as several separate, named steps, not one giant adjustment.

Noise floor — The quietest sound a recording system produces on its own (its inherent hiss); dialogue must sit well above it so it stays clean when raised in post.

Noise reduction — The tool at the center of cleanup: it identifies steady, unwanted background sound (drone, hum, hiss, the constant character of a room) by learning a "noise print" — ideally from recorded room tone — and subtracts that fingerprint from the whole clip, lowering the noise while leaving the voice. Modest amounts (≈8-10 dB) only; overdone, it makes the voice sound "underwater."

Nose room (looking room) — The space left in front of a subject's gaze — the direction they are looking. A face looking off-screen with no room in front of it feels trapped; the eye wants somewhere for the look to go. Place the subject on the third opposite their look so the space opens in front of them.

O

Off-axis eyeline — The standard nonfiction-interview convention in which the subject's gaze is directed slightly off the lens axis, at an interviewer seated just beside the camera, so the viewer becomes an observer of a real conversation rather than being addressed directly.

Offload — The physical act of copying media files from a card to a drive; the first, protective half of ingest. Distinct from the import (linking media into the project). Cards are transport, not storage — offload before you edit, always.

Open captions (burned-in) — On-screen caption text rendered permanently into the picture, seen by everyone in the style the maker designed. The short-form default, because it guarantees the muted-autoplay majority reads the words and the maker controls the look and placement. Contrast with closed captions — a separate, toggleable/auto-generated text track (increasingly auto-created by platforms, but error-prone and requiring proofreading).

Open shade — An outdoor area shielded from direct sun but still open to the bright sky, lit softly and indirectly by cool skylight (~7000–8000K); the go-to soft, flattering light on a harsh sunny day. Gains direction at the edge of the shade, facing the open sky.

Over-the-shoulder shot (OTS) — A framing of one person shot over the near shoulder of the other, so the listener's presence is felt in the foreground; a workhorse of shot-reverse-shot. The near shoulder should match that person's side of the frame from the wide.

Overcast / diffused daylight — Sunlight scattered by cloud so the entire sky becomes one enormous, soft, nearly shadowless source — the largest softbox there is. Soft, even, and consistent all day, but flat (no modeling), cool, and top-heavy.

P

Pacing — The rate and rhythm at which shots change and information arrives — how long each shot is held and how quickly cuts come. The video's pulse: quick, short cuts raise energy and tension; long holds add calm and weight. The hold (choosing not to cut) is pacing's most powerful tool. First assemblies are almost always too slow.

Pan — A horizontal pivot of the camera in place: the camera stays in one spot and rotates left or right, like turning your head to follow something across a room. A rotation, not a translation — the camera does not travel through space. (Short for "panorama.")

Parallel action — Two (or more) lines of action understood by the audience to be happening simultaneously; what cross-cutting depicts. The "meanwhile" that only editing can speak.

Performance — What a person does in front of the camera that a viewer reads as truthful or false — their behavior, delivery, energy, and presence in the moment. Not limited to acting: a testimonial, a how-to, and a reaction to a text message all have a performance. It is simply behavior the camera believes. Small, specific behavior reads as true; big, manufactured behavior reads as fake, because the viewer's radar for false human behavior is instant and merciless.

Personal brand — The consistent impression your work and presence leave on the people who encounter them: your recognizable look, your voice and values, and the feeling clients associate with working with you. It is built through consistency, not claimed in a bio, and is distinct from a client's brand guidelines (Ch.22).

Platform delivery spec — The complete set of technical requirements a destination expects a finished file to meet: resolution, frame rate, codec, container, bitrate, loudness, aspect ratio, caption format, and sometimes length or file-size limits. The answer key for the export dialog, and the generalization of Chapter 23's "platform specs" to every home (web, social, broadcast, client). Changes constantly — always confirmed at the source (Appendix H / the platform).

Platform specs — The technical delivery requirements a given platform imposes or prefers for a given kind of video: aspect ratio, resolution, frame rate, allowed length, loudness normalization target, file/codec, and caption format. Match them and the video plays as intended; miss them and the platform crops, compresses, or turns the work down. Specs change constantly and should always be verified against the current platform guidance (Appendix H/J).

Polar pattern — The map of a microphone's directional sensitivity — which directions it hears loudly and which it rejects. Main patterns: omnidirectional (all directions, most lavs), cardioid (front + sides, rejects rear), supercardioid/hypercardioid (tighter front, small rear lobe — best for interiors), and shotgun/lobar (narrow front lobe, long reach). Knowing the pattern lets you aim the sensitive ("on-axis") zone at the mouth and the deaf ("off-axis") zone at the noise.

Portfolio — The fuller body of full-length finished work behind the reel — your individual pieces, watchable in full by anyone the reel has convinced. The reel is the door; the portfolio is the house.

Post-production — The third stage ("post"): everything after the shoot — ingesting and organizing footage, editing, color correction and grading, sound mixing, titles and graphics, and export.

POV shot (point-of-view shot) — A shot taken from where a character's eyes are, so we see what they see. It works only when paired with a shot of the person looking, which supplies whose view it is; the view shot alone does not.

Power window — A shape or mask (circle, rectangle, oval, or freely drawn) that limits a grade to a region of the frame, and that can track a moving subject. Resolve's term; layer-based tools call it a mask or shape. Isolates by shape.

Practical light — A light source that actually appears within the frame (a table lamp, a neon sign, a candle, a laptop or TV screen, café counter pendants) and lights the scene at the same time. Practicals motivate other lights, add depth and interest to the background, and can themselves serve as a key or rim.

Pre-production — The first stage: everything before the camera rolls — idea, story, script, storyboard, shot list, schedule, budget, location scout, gear check. The cheapest stage in which to solve a problem.

Presence range — Roughly 2-5 kHz, the region whose modest boost adds consonant clarity and lets a voice "cut through" a mix.

Pricing — The deliberate craft of deciding what your work is worth and how you charge for it — built from your real costs, the time a job takes, your market, and the value the finished video creates for the client, rather than a figure plucked from the air. You should be able to say out loud why the number is the number.

Primary correction — Adjustments that affect the whole frame at once (global exposure, contrast, and color balance), as distinct from secondary correction, which isolates and changes only part of the frame (Chapter 32).

Prime lens — A lens with a single fixed focal length; to change framing you move the camera. Usually optically simpler, so often sharper, faster (wider maximum aperture), lighter, and cheaper at a given quality — and its one focal length is secretly a teacher, forcing you to commit to a perspective.

Product video — A video whose subject is the product itself — showing what it is, what it looks like, how it works, and why it matters, to make a viewer understand and want it. Comes in two often-combined flavors: the hero (the beauty film that makes the thing desirable — form, texture, craft) and the demo (the functional piece that shows it working and the benefit it delivers). The product-on-a-table setup; its central challenge is controlling reflections, and its central discipline is selling the benefit, not the feature.

Production — The second stage: the shoot itself, when the camera rolls and footage, light, sound, and performance are captured.

Program feed — The single selected output of a switcher: the "live cut" — the one stream of what the audience is seeing at any instant (often labeled PGM / program). The rhythm of live switching is preview it, then take it to program. Distinct from a board feed (which is audio from the venue's mixing desk).

Project handoff — Packaging a project so it can be opened and continued on a different computer, or by a different person — with every piece of media, every dependency (fonts, LUTs, plugins, source graphics), and the project file itself traveling together and relinking cleanly on the other side.

Project rate (flat/fixed bid) — One price for the whole deliverable regardless of hours; predictable for the client, but you eat any overage if you underestimate — hence the need for a tight scope (§38.1–38.2).

Property release — The equivalent of a model release for places and things: permission from an owner (or authorized manager) to depict recognizable private property, a distinctive private location, or protected artwork/logos in published work. Formalized for a shoot as a location agreement.

Proxy — A lightweight, easy-to-play stand-in copy of a heavy original clip (lower resolution, lower bitrate, an easy all-intra codec). You edit with the proxy for smooth playback and switch back to the full-quality original only at export. Proxies are disposable and regenerable; the originals are the master and are never deleted.

Public domain — Work whose copyright has expired or been waived, genuinely free to use; but terms vary by country, and a new recording/edition of a public-domain work can carry its own fresh copyright. (§38.5)

Push-in — A move in which the whole camera physically travels toward the subject, so the framing tightens as if you stepped closer — made on a dolly, slider, gimbal, or a braced step. Its reverse is a pull-out (the camera travels away, opening the frame). Distinct from a zoom: a push-in moves through space and produces parallax (near and far objects shift relative to each other), so the viewer feels themselves approaching, whereas a zoom only magnifies optically from a fixed spot.

Q

Qualifier — A key that isolates a grade by selecting a color/hue/saturation/luma range, so the adjustment touches only matching pixels wherever they appear in the frame. Isolates by color; the workhorse of skin protection.

Question design — The craft of writing and sequencing interview questions so they produce usable, story-carrying answers: open rather than closed, specific rather than vague, and phrased to invite a full-sentence reply.

Quote / estimate — A written, itemized statement of the price and terms sent to the client before work begins; the seed of the contract, and a first defense against scope creep via its INCLUDED / NOT INCLUDED block. (§38.1)

R

RAW — A recording that keeps the sensor's near-unprocessed readings — the raw per-photosite brightness values captured before demosaicing reconstructs full color and before a picture profile bakes in contrast, color, or a fixed white balance — so the image is reconstructed in post. It offers the maximum latitude in all of capture (white balance becomes a nearly free post decision; maximum dynamic range and bit depth survive) at the maximum cost (enormous files, a demanding storage/computer/grading pipeline), and is a deliberate specialist choice, not a default.

Repurposing (horizontal → vertical) — Turning a video shot in one aspect ratio (usually 16:9) into another (usually 9:16) so it feels made-for-the-format. Three honest methods: crop-and-reframe (keyframe the crop to follow the subject), stacked/letterbox (preserve the whole frame and use the freed space for text), and blur-fill (a fallback). Best avoided by "shooting for the crop" — composing horizontal subjects centered and loose so a vertical crop survives.

Resolution — The number of pixels in the image, given as width × height (1920×1080) or by a shorthand name (1080p, 4K). Physically, how many of the sensor's "buckets" are used to hold the picture; more pixels means more detail and more reframe headroom, at the cost of storage and computer load.

Retainer — An ongoing arrangement where a client pays a set amount each month for a set amount of work, converting unpredictable project income into recurring, predictable income. (§38.6)

Retention / watch time — The measure of how much of a video people actually watch: average view duration, the percentage of the video the typical viewer sees, and the shape of the retention curve (how many viewers remain at each second). It is the primary signal platforms use to decide whether to show a video to more people, because it is the clearest evidence the video holds attention. Diagnosed by curve shape: an early cliff = a weak hook; a mid-video sag = a dull stretch; a late bump = rewatches/a clean loop.

Revision round — One consolidated set of client feedback (a single list of notes), not each comment as it arrives; the unit a revision policy caps. (§38.3)

Revision vs. new request — A revision refines the agreed deliverable (a fix, covered by included rounds); a new request is a different/additional thing (new work, billed via change order). (§38.3)

RGB parade — A scope showing three brightness traces side by side — one each for the Red, Green, and Blue channels — used to spot and fix color casts: on a neutral area the three should sit at the same heights; a channel riding high or low reveals the cast and where in the tonal range it lives.

Rhythm (in the edit) — The felt pattern of shot lengths and cut timing — the pulse of a sequence — including whether each individual cut lands on the right frame. Distinct from pacing (the overall speed of a piece, Ch.26): pacing is how fast the piece moves; rhythm is the pattern of the beats within that speed.

Riding the levels (automation / clip gain) — Manually raising quiet moments and lowering loud ones over time by drawing volume changes on the timeline; the most transparent way to even out dialogue dynamics.

Rim/back light (also back light, hair light, kicker) — A light placed behind and usually above the subject, pointing back toward the camera, that skims the subject's edges (hair, shoulders) to create a bright outline separating them from the background and restoring depth. It reads only when the background is darker than the lit edge.

Rolling shutter — The skew, wobble, or "jello" distortion that appears when a subject or the camera moves fast, caused by most sensors reading their photosites line by line (top to bottom) rather than all at once — so the bottom of the frame is captured a moment later than the top, and straight lines lean. Reduced by slower camera moves; eliminated only by a (rare, costly) global shutter.

Room tone — The ambient sound of a location when no one is talking and nothing is happening (fridge hum, HVAC hiss, faint traffic, the character of the air). Every room has one; true digital silence sounds dead. Used in the edit to smooth cuts and blend takes. (Term first-defined in Ch.14 §14.1; the practice of always recording it is owned by Ch.15.)

Roto (rotoscoping) — Drawing a mask and animating it frame-by-frame (with keyframes) to follow a moving subject or object that cannot be keyed; the manual alternative to a chroma key.

Rough cut / first cut — The first complete, watchable version of an edit: every beat present and in order, roughly the right length, but not yet trimmed to the frame or polished. Sits on the editorial ladder above the string-out (which has no story shape yet) and below the fine cut (Chapter 29's polished, precise version).

Royalty-free — A licensing model in which you pay once (or subscribe) and owe no ongoing per-use royalties; you still obtain the license and use the asset within its terms. NOT the same as "free." (§38.5)

Rule of thirds — A composition guideline: divide the frame into a 3×3 grid with two evenly spaced vertical and two horizontal lines, and place important elements along those lines or on the four points where they cross (the "power points"), rather than dead-center. It is the correct default for placing a subject, not a law — symmetry and centering are deliberate exceptions.

Run-of-show — The written order of an event (processional, vows, kiss…; or doors, keynote, panel, award…) with rough timings and the shooter's must-get moments marked; the "script" for a thing you don't control. (Used inline in Ch.18 §18.1; developed as an event tool here in 24.1.)

S

Safe zones — The region of a vertical frame that stays reliably visible and uncovered by platform interface and cropping. The platform's own graphics — username and caption (bottom-left), the like/comment/share/save button stack (right edge), the progress bar (very bottom), and the app header (top) — cover the edges, so faces, key action, and on-screen text must sit inside the action-safe center column. (Previewed lightly in Chapter 6 §6.5; formally defined here.)

Safety track (backup track) — A second recording of the same mic set noticeably lower (often ~−12 dB), so a surprise clip on the main track is captured clean on the safety; standard insurance for unrepeatable moments.

Schedule — The plan for how a shoot's available time will be spent: the order in which shots are captured and the time allotted to each, turning a shot list into a timed plan for the day. Built in efficient (grouped) order rather than story order, around fixed points (light, quiet, availability), with buffer, and with must-have shots front-loaded.

Scope creep — The gradual, unbudgeted expansion of a project beyond what was agreed — extra deliverables, versions, revisions, "small" additions — each request individually reasonable-sounding, all of them together fatal to time and profit. Defended with a specific SOW, a capped revision policy, and change orders. (Previewed in Ch.22 §22.6; owned here.)

Scopes — Real-time graphs that measure the actual signal in footage and display it as objective numbers, immune to the eye's adaptation and a monitor's quirks. The three essential scopes are the waveform, the RGB parade, and the vectorscope.

Scratch track (reference track) — A rough reference recording from the camera's own mic, kept rolling on a double-system shoot for sync (it carries the clap spike) and as a backup; never used in the final mix.

Screen direction — The consistency of left, right, and facing across a scene that the line preserves (a subject moving screen-left-to-right keeps moving that way across cuts). Introduced here as the reader's compass; its full continuity treatment — including what breaks when it is violated — belongs to Chapter 9.

Screen replacement — Replacing what appears on a phone, laptop, TV, or monitor in a shot with a controlled image, via a corner-pin/planar track and added glow/reflection/glare.

Script — The written blueprint of a video's content: what is said and what is seen, laid out in sequence. The two forms most used in practical (nonfiction) video are the two-column (audio/video, or A/V) script — VIDEO in the left column, AUDIO in the right — and the outline script, which plans the beats, questions, and B-roll for interview-driven work whose words cannot be written in advance. (The screenplay, or master-scene format, is the tool for invented dialogue performed by actors.)

SDH (Subtitles for the Deaf and Hard-of-hearing) — The fullest form of same-language captions: dialogue plus meaningful non-speech sound cues ([phone rings], speaker changes). Contrasted with translation subtitles, which render dialogue in another language and typically omit sound cues.

Secondary — A color adjustment applied to only part of the frame — a region, a shape, or a specific color range — as opposed to a primary, which affects the whole image (Ch.31). Isolated with a power window (by shape) or a qualifier (by color).

Select — A clip, or (far more often in an interview) the good part of a clip, that you have marked as a keeper and set aside to use. In an interview a select is almost always a single soundbite: one self-contained sentence or thought, carved out of a long take with an in-point right before the first word and an out-point right after the last, on the breath. Gathered into a Selects bin and labeled by content, not take number. (Previewed in Ch.27 §27.5; given its full formal definition here as owner.)

Sensor — The flat, light-sensitive silicon chip at the heart of a digital camera that converts the light falling on it into an electrical signal, which the camera turns into a grid of brightness numbers — a picture. Its grid of light-catching photosites is where resolution and exposure physically originate.

Sensor size — The physical dimensions of the sensor, from a fingernail-sized phone sensor to full-frame (~36×24 mm) and larger. Distinct from resolution; it chiefly affects low-light performance and how easily the camera produces shallow depth of field, and it is a set of trade-offs (light and blur vs. size, weight, and cost), not a quality ranking.

Sequence — A coherent series of shots of a single action, covered from different sizes and angles — classically wide, medium, and detail — shot so they cut together into one complete, compressed rendering of that action. Coverage (Ch.7) applied to a process instead of a conversation; the highest-value B-roll you can shoot.

Set etiquette — The customary rules of conduct and communication on a shoot that keep it efficient, respectful, and — above all — safe: the verbal protocol of a take ("rolling," "action," "cut," "that's a wrap"), quiet and stillness while rolling, staying in your lane, clear communication of hazards, respect for the chain of command and for people, and the distributed authority for anyone to stop the shoot for safety. Part manners, part protocol, part safety code.

Shock mount — An elastic suspension that floats a mic in its cradle so vibration and handling noise cannot travel into it.

Shot list — An itemized, ordered list of every shot to be captured, each with its size, angle, subject and action, and notes on movement, lens, audio, location, and priority; used on set as a checklist so nothing is forgotten. The single most valuable pre-production document for a working shooter, and where "shoot for the edit" becomes a line you cross off.

Shot sizes — The standard vocabulary for how much of the subject fills the frame, measured by long convention against the human figure — from an extreme wide (a person a speck in a landscape) to an extreme close-up (a single eye filling the screen). A shot size is a decision about attention: the more a subject matters to the story at that moment, the larger it should be in the frame.

Shot-reverse-shot — The pattern of alternating angles in a two-person exchange: a shot favoring one person, then the reverse favoring the other, back and forth, every setup shot from the same side of the line. The most common structure in narrative video.

Shot-size extensions (EWS/ELS, MLS, MCU, ECU) — The full ladder around the three anchors: extreme wide / extreme long (subject tiny, place is everything); medium long (MLS, mid-thigh up, the "cowboy"); medium close-up (MCU, chest-and-head, the talking-head/interview standard); extreme close-up (ECU, one isolated detail — an eye, a phone, a hand). Abbreviations are defined on first use and used freely thereafter.

Shotgun mic — A long, narrow, highly directional microphone that hears a tight zone straight in front and rejects much of the sides and rear, using an interference tube to cancel off-axis sound. Excellent outdoors and on a boom; still obeys close-is-king (directional, not "telephoto for sound"). Indoors in a small room its tube can gather reflections and sound roomy — a supercardioid often does better there.

Show-don't-tell — Conveying meaning through image, action, and behavior that lets the viewer draw the conclusion themselves, rather than stating the conclusion in words. Works because a conclusion a viewer reaches from evidence is one they own and believe.

Shutter speed / shutter angle — How long each individual frame is exposed to light, written as a fraction of a second (1/50 s) or, in cinema terms, as an angle (180°). It controls motion blur: a longer shutter blurs moving subjects; a shorter one freezes them into stuttery, staccato motion.

Sidecar captions (closed captions) — Caption text stored in a separate timecoded file (.srt, .vtt) that the player or platform overlays on demand; toggleable, multi-language, searchable, screen-reader-friendly, and correctable after upload. Used for YouTube, broadcast, client work, and the archived master.

Sidechain — Using one signal (the dialogue) to control a processor on another (a compressor on the music), most commonly to duck music under speech automatically.

Single-system sound — Recording the audio inside the camera, in the same file as the picture (the way a phone does by default); simple, with nothing to sync, but tied to the camera's electronics and position.

Skin-tone line — The specific direction on the vectorscope, between the red and yellow targets (about 11 o'clock), along which healthy human skin of every complexion falls; complexion changes how far out along the line the trace sits, not the angle.

Slate — The board (traditionally a clapperboard, or "sticks") shown to camera at the head of a take that identifies the shot (production, scene, take, date, roll, often director and DP) and, when it claps, gives the editor a matching picture-frame and audio-spike to sync picture to separately recorded sound. It does two jobs at once: it labels the take so the edit can find it, and it syncs it. Solo version: hold a hand in frame, say the shot and take number aloud, and clap once ("self-slate").

Social proof — The persuasive principle behind the testimonial: people trust the experience of a peer over a seller's own claims. A prospect discounts what a brand says about itself but believes someone who was in the same situation (§22.3).

Soft light — Light from a source that is large or close relative to the subject; its many-angled rays produce soft, gradual shadow edges that wrap gently around the subject. Examples: an overcast sky, a big window, bounced light. Flattering and natural. (The single variable that sets hard vs soft is the apparent size of the source as seen from the subject.)

softbox — A modifier consisting of a fabric enclosure that mounts over a light so the source shoots through a front diffusion panel, turning a small hard emitter into a large, controllable soft rectangle; black sides keep the light from spilling where it isn't wanted.

Sound effects (SFX) — Added, non-musical sounds that either sync to an on-screen action or fill the world off-screen. Two kinds: a continuous ambience bed (establishing place, often looped room tone) and discrete spot effects (a door, a cup, footsteps) placed frame-accurately against the picture.

Sound-off viewing — The default consumption mode of a social feed: autoplay starts muted and a large share of viewers (often the majority on the first pass) never unmute. It requires that a short-form video be fully understandable from picture and on-screen text alone, with audio rewarding — not gating — comprehension.

Split edit — The umbrella technique for any cut where the audio and video edits do not fall on the same frame; the J-cut and the L-cut are its two forms (sound leading or sound lingering). Made by unlinking audio from video and trimming one edge past the other.

Spot effect — A discrete sound effect tied to a specific moment or action (a door bell, a cup, a chair), placed frame-accurately against the picture.

Statement of work (SOW) — The part of a contract (or its own document) that spells out exactly what will be delivered — the specific videos, lengths, formats, revision rounds, and what's included and NOT included; the fence around the job. (§38.2)

Stems — Grouped tracks in a mix, one group per kind of sound (dialogue, music, effects, ambience); kept separate to control each independently and to deliver a music-and-effects (M&E) version.

Stock elements — Pre-made, licensed image/footage assets composited into a shot rather than filmed: skies, backgrounds, particles (smoke, fire, rain), atmospheric overlays (haze, god rays, light leaks, lens flares), textures, clips.

Stop (of light) — One doubling or halving of the amount of light in the image. It is the shared unit of every exposure control (aperture, ISO, shutter, ND), which is what makes them interchangeable: a stop is worth the same amount of light no matter which control provides it.

Story beat — A single unit of story: one moment where something turns — new information lands, or a question opens or closes. A beat is not a shot or a sentence; a single beat may span several shots, and one shot may contain several beats.

Storyboard — A sequence of simple drawings, one per shot or key moment, that shows the framing, composition, and action of a video before it is shot: a comic strip of the film. Drawing skill is irrelevant — stick figures and boxes are standard; the purpose is to make framing, coverage, and cutting decisions on paper, where they are free to change.

String-out — Selects laid end to end on the timeline in a rough, first-pass story order — not trimmed to the frame, not covered with B-roll, not scored. Its interview form is the radio string-out: the soundbite spine as playable audio, tested by listening with the eyes closed. (Previewed in Ch.27 §27.5; given its full formal definition here as owner.)

SubRip (.srt) / WebVTT (.vtt) — The two universal sidecar caption file formats. .srt is minimal (number, HH:MM:SS,mmm --> HH:MM:SS,mmm timecode range, text, blank line, repeat); .vtt is its web-oriented cousin with more styling. Both are plain text, hand-editable in any text editor.

Switcher — A device (hardware or software) that takes multiple live camera inputs and lets you cut, dissolve, or wipe between them instantly, sending out one selected feed. Also called a vision mixer. Comes at every price including free (OBS Studio is the standard free software switcher). Most switchers show a preview (PVW) of the next angle beside the live output so you can line up a cut before taking it.

Sync — Aligning separately-recorded audio to its picture so that lips and sound match again; made trivial on set by a clap (a sharp transient spike that appears in both files) or by shared timecode.

Sync (in the edit) — The editorial act of aligning your separately recorded (double-system) audio to its picture on the timeline so the two play back as one. Done three ways, most manual to most automatic: by the clap/slate (align a shared transient spike by hand), by waveform auto-sync (the software matches waveforms), or by timecode (clips share a clock and snap into place). (Builds on Chapter 15's general definition of "sync" — Ch.15 owns the on-set/practice sense; Ch.27 adds the edit-action facet.)

Sync license / master-use license — The two rights needed to use a specific recording of a song in a video: a sync license for the composition (song), and a master-use license for the sound recording; both are required, which is why hit songs are expensive/slow to clear and royalty-free libraries bundle both. (§38.5, 🔬 The Tech)

Synthetic media — Imagery, video, or audio generated or substantially altered by software (increasingly AI) rather than captured from reality — a swapped face, a cloned voice, an invented "person."

T

Testimonial — A video in which a real customer, client, patient, employee, or user tells their genuine story — the problem they had and how this product/service/organization solved it — in their own words, to build trust and persuade a peer. Mechanically it is the interview (Ch.19) aimed at persuasion; it works by social proof and persuades on specifics, not applause. Structure it Problem → Solution → Result; steer the structure but never script the content.

The 180-degree rule — The rule that you keep every camera on one side of the line for all shots in a scene (within the 180-degree arc on that side). Doing so keeps each subject in a consistent screen position and looking in a consistent direction across every cut, so all the angles cut together. (Not to be confused with the 180-degree shutter rule of Chapter 2, which concerns motion blur, not camera position.)

The 180-degree shutter rule — The convention that a natural-looking shutter is roughly one over double the frame rate: shutter ≈ 1 ÷ (2 × frame rate). At 24 fps that is 1/48 (set 1/50); at 30 fps, 1/60. Named for the half-open (180°) rotating disc of film cameras; it records the amount of per-frame motion blur the eye reads as natural.

The 30-degree rule — The guideline that, when cutting between two shots of the same subject, the camera should move at least about 30 degrees around the subject between setups (and ideally change shot size), so the two framings read as two distinct viewpoints rather than one view with a jump in it. Less than ~30° and the brain reads the cut as a glitch; ~30° or more, especially with a size change, and it reads as a clean, motivated new perspective. Not to be confused with the 180-degree rule: the 180° rule governs which side of the line you stay on; the 30° rule governs how far you move between shots on that side.

The assembly — The first pass of an edit: laying your chosen ("keeper") shots onto the timeline in story order, end to end, so the whole piece exists and can be watched start to finish for the first time. Deliberately rough — no polished trims, no B-roll, no transitions, no color, no mix — because its only job is to make the scene watchable whole so you can judge and shape it. Also the shoot's most honest report card.

The brand kit — The working subset of brand guidelines a video actually uses (logo, colors, type, tone, visual style, casting, music), extracted and confirmed before a brand shoot (§22.2, FIGURE 22.2).

The coverage plan — A B-roll shot list, drawn directly from the story beats, that names every cutaway, insert, and sequence the edit will need and lets you tick each one off as you get it. The specialized, documentary-facing form of the shot list (Ch.16) and the coverage checklist (Ch.7); the pre-production guarantee that you leave a location with enough.

The director's role — Owning the answer to two questions — what is this scene about? and how should it feel? — and serving that intention through two halves: decisions (keeping every choice consistent with the why, and killing choices that have no reason behind them) and tone (setting the emotional safety of the set so a performance can happen). Most of the role is communication, not camera; the performance you capture is capped by the safety you create. On a solo shoot you hold the role even if you never say the word "director."

The dolly — A wheeled platform the camera rides on to travel smoothly, historically along laid track (hence a "dolly in/out," and "tracking"). Any traveling camera shot is loosely a "dolly shot." A slider is a short rail (often only a foot or two) for small, smooth push, pull, or lateral moves without a full dolly. On a budget, the "dolly" can be a wheelchair, office chair, skateboard, or the operator's braced body.

The emotional cut — A cut made to serve what the audience should feel at that instant, placed ahead of logic, information, or continuity. The top priority of the Rule of Six; often a decision to hold (cut in on the feeling, hold past comfort, leave before it resolves).

The fine cut — The stage of the edit after the rough cut and assembly where you refine the timing of every cut, frame by frame, toward a locked version — trimming the fat, adjusting rhythm, and protecting the emotion — until nothing can be removed without the piece getting worse.

The frame — Everything the camera captures at a given instant: the rectangle of the image and every choice about what is included in it and what is deliberately left out.

The funnel (awareness → consideration → conversion) — The viewer's journey from stranger to customer; each stage wants a different video and a different CTA. A wrong-stage CTA ("buy now" to a stranger) wastes the video (§22.5).

The hook — The opening of a video, usually the first few seconds and at most the first ten, whose job is to earn the viewer's attention and make a promise about why the next minute is worth their time. The most valuable seconds in the piece.

The interview setup — The repeatable physical arrangement of subject, camera, interviewer, light, and microphone for a sit-down interview — framing, eyeline, and the interviewer's position relative to the lens — built before the conversation starts.

The invisible cut — Not a specific cut but the governing principle: a cut disappears when something continuous (sound, motion, form, idea, or held rhythm) carries the eye or ear across it, and announces itself when nothing does. The editor's core question at every seam is "what carries the viewer across?" A visible cut (a deliberate jump cut, a hard cut to silence) is a legitimate choice; the amateur's error is a cut that shows by accident.

The line / axis of action — The imaginary straight line connecting the two subjects of a scene (or the line of a single subject's movement or look). It is the most important line on any set and is carried in the shooter's head, not painted on the floor; it is the reference for the 180-degree rule.

The look — A piece's deliberate, consistent visual signature — its palette, contrast, and color character — that a viewer reads as mood even without being able to name it. A look is a decision applied across a whole piece, not a single graded shot.

The mix — The balanced blend of all sound elements in a video — the act and result of setting every element's level, tone, and placement so they combine into one soundtrack in which nothing fights and, above all, the dialogue is always clear. Built dialogue-first.

The non-answer — A reply that cannot be used as a self-standing statement in the edit — a yes/no, a fragment, an echo of the question, an "it depends," or an evasion — the raw material that becomes mush.

The open loop — A curiosity gap a hook opens but does not immediately close (a question, a promise, a "wait for it"); the viewer stays because leaving means never closing it. The engine underneath most strong hooks; honest when the loop is eventually closed, a cheat (bait-and-switch) when it is not.

The paper edit — The practice of working out a piece's story shape and order away from the timeline — on paper or in a plain document — before cutting, to find the story cheaply. (Introduced here as a general story-finding tool; the interview-specific radio edit, where you cut the spoken words first, is owned by Chapter 30.)

The radio edit — A paper edit built entirely from an interview's audio: you find and order the story using only the spoken words, with your eyes closed to the picture, so the piece works as a piece of radio before a single frame of image is laid over it. The specialized, interview-driven form of the paper edit (introduced generally in Ch.29). Also called a radio cut. Its raw material is a timecoded transcript; if the story holds for the ear alone, the pictures can only improve it.

The reality arc — The beginning, middle, and end a documentary maker discovers in real material and builds in the edit, rather than a plot imposed on it. Same shape as a fiction narrative arc (hook, question, development, turn, resolution, button) but arrived at backward: you shoot the reality, then find the arc inside it. Built from a character with a want and an obstacle, a spine question, and a turn.

The shot — A single continuous run of the camera, from the moment recording starts to the moment it stops. Finished videos are made of shots, arranged.

The social hook — The first roughly two seconds of a vertical video, engineered to stop a scrolling thumb and buy the next few seconds. The short-form cousin of the narrative hook (Chapter 17 §17.3): where the narrative hook has ~10 seconds to hold a committed viewer, the social hook has ~2 seconds to win commitment from a viewer actively scrolling away, competing not with other videos but with the scroll itself. It works the eye (a striking image), the ear (first words on the payoff), and the reader (on-screen text) at once, and opens a curiosity "loop" the viewer must stay to close. It is assembled in the edit — the best two seconds moved to the front — not simply filmed first.

The timeline — The core workspace of an NLE, where clips are laid out in time on stacked tracks. Horizontal distance is time (left is earlier; a clip's width is its duration); vertical position is layers (higher video tracks sit on top of and cover lower ones). Video tracks (V1, V2…) sit above audio tracks (A1, A2…), with a playhead marking the current frame against a timecode ruler.

Three-act structure — The division of a story into a setup (Act 1: the normal world and the inciting problem/question), a development (Act 2: the pursuit and its rising complications), and a resolution (Act 3: the turn/climax and a new normal). The most common dramatic shape; it scales from a 15-second clip to a feature.

Three-point lighting — The foundational lighting setup built from three sources, each with one job: a key (sets exposure and the direction of light — shape), a fill (controls how deep the shadows go — contrast/mood), and a rim/back light (separates the subject from the background — depth). A starting grammar to be learned and then broken deliberately, not a requirement; many strong looks use a single light.

Tilt — A vertical pivot of the camera in place: the camera pivots up or down from a fixed point, like nodding — tilting up to reveal height or scale, tilting down from a face to the hands. Like a pan, it is a rotation around a fixed camera position.

Timelapse — A shot built by capturing frames at a slow, fixed interval (seconds to hours apart) and playing them back at a normal frame rate, so that a long span of real time compresses into seconds and slow motion becomes visible (clouds race, sun sets, crowds swarm). The interval is the central creative decision; it must match the subject's speed, and exposure and focus must be locked.

Title — On-screen text that names or frames the piece or one of its sections: the opening title, a section/chapter card, or the end card. Usually the first designed thing a viewer sees, so it frames how they judge everything after it.

Tracking shot — A traveling shot that moves with a moving subject — keeping pace alongside, ahead of, or behind them so they stay roughly the same size in the frame while the world streams past. The engine of the walk-and-talk. (On a dolly it runs on track; on a gimbal or braced handheld you simply move with the subject.)

Transition — Any way of moving from one shot to the next that takes time, blending or replacing shot A with shot B over some duration rather than in a single frame (dissolve, fade, wipe). Distinct from the cut (a transition of zero length). Each transition carries a meaning; use one only when it is motivated, and default overwhelmingly to the cut.

Treatment — A short prose description (usually one to three paragraphs) of the video you intend to make, written before any script, that fixes the essential decisions: what it is about (the logline/story), who it is for, how long it runs and where it will live, what it feels like (tone), and what the viewer should think, feel, or do at the end. The finished video described as if you had already seen it.

True peak (dBTP) — The actual peak of the reconstructed analog waveform, which can overshoot the highest digital sample; a true-peak limiter (ceiling typically -1 dBFS) predicts and prevents these inter-sample "overs."

Two-mic safety — (§14.4) Recording a lav and a boom on important dialogue so one backs up the other; the concept is deepened for interviews in Ch.19. Not a reserved term.

V

Value-based pricing — Pricing by the value the video creates for the client (the business outcome) rather than by your hours; enabled by understanding the client brief (Ch.22 §22.1). (§38.1)

Vectorscope — A circular scope that shows color only: the direction from center indicates hue and the distance from center indicates saturation. Center is neutral grey (zero saturation). Its skin-tone line (roughly 11 o'clock, between red and yellow) is the target every complexion's healthy skin falls along.

Verified copy (checksum copy) — A copy that re-reads every byte it wrote and confirms it matches the source, catching a silent copy error while the source card still exists — as opposed to a naked drag-and-drop, which can copy a corrupt file without warning.

Vertical video — Video composed for a tall frame — almost always the 9:16 aspect ratio — designed to fill a phone held upright, edge to edge, with no black bars. It is not a horizontal video rotated or cropped; it is a frame you compose for, favoring a single, closer subject and stacking elements top-to-bottom rather than spreading them across the width.

VFX (visual effects) — Any imagery in the final frame created or altered outside the live moment of filming: composites, CGI, set extensions, screen replacements, removals/clean-ups, matte paintings. Distinct from practical/"special" effects, which happen in front of the camera on the day.

Video production — The craft of turning an idea into a finished video through three stages of deliberate decisions: pre-production (planning), production (shooting), and post-production (assembling).

Visual balance — The distribution of visual "weight" across the frame so the composition feels intentional rather than lopsided by accident. Weight is pull, not size (a face, brightness, sharpness, contrast, saturated color, and motion are all heavy). Balance can be symmetrical (equal weight both sides — formal, ordered) or asymmetrical (a subject on a third answered by a smaller weight or considered negative space on the other side — the more common mode).

Voiceover / narration — Recorded spoken commentary laid over the picture rather than spoken on camera. It comes from three sources: a scripted external narrator (the "voice of God"), the filmmaker's own voice, or an interviewee's audio lifted off its sync picture and used over B-roll. Good narration adds only what the pictures and soundbites can't say, then gets out of the way.

Vérité — The observational or "fly-on-the-wall" mode (from cinéma vérité / direct cinema): the camera acts as a witness to real life unfolding and tries to influence it as little as possible — usually no narration and often no interviews. Its power is access and unbroken continuity; its cost is control and high shooting ratios.

W

Waveform (monitor / scope) — A live graph of image brightness, with the horizontal axis matching left-to-right frame position and the vertical axis running from pure black (0) at the bottom to pure white (100) at the top. The main tool for judging exposure objectively; it reveals clipping (trace piled at 100) and crushing (trace piled at 0).

Whip pan — A very fast pan (also "swish pan") in which the image smears into motion-blur streaks. On its own, a jolt of energy; its most powerful use is as an in-camera transition — whip out of one shot and into the next in the same direction, then cut at the blurriest frame, and the two whips fuse into one continuous-looking move that hides the seam.

white balance — The camera setting that tells the sensor which source is "white/neutral," so that whites render white and other colors render accurately; the camera shifts the image opposite the source's color to cancel its cast. Can be set deliberately "wrong" to warm or cool an image for mood.

White balance (in post) — Neutralizing a color cast after the shoot by rebalancing the red, green, and blue channels until something that should be neutral (a white shirt, a grey card) reads neutral. The post-production counterpart to the in-camera white-balance control from Chapter 12.

White point — The brightness of the brightest part of the image, set on the waveform (via gain) up to about 100% without blowing highlight detail past the ceiling.

Wide shot (WS) / long shot (LS) — A framing that shows the whole subject head-to-toe together with their surroundings. Its job is to establish who someone is and where they are — the geography, scale, and body language of a space. The first shot of a scene is often a wide (an establishing shot).

Wild sound — (also nat sound) Audio recorded wild — not synced to a specific line — to be laid under B-roll in the edit (the hiss of the steam, the tap of a knife, a shop's hum). The B-roll cousin of room tone (Chs. 14–15); it makes B-roll feel alive instead of like a silent slideshow. (Introduced as a working term this chapter; not a ledger-owned first-define.)

Wind protection — Shielding a microphone from moving air (which strikes the diaphragm as low-frequency roar and thumps): a foam windscreen for indoor air, breath, and light breeze; a furry cover ("dead cat"/windjammer) for real outdoor wind; plus positioning your body between the wind and the mic. A sock works in a pinch.

Window light — Daylight entering through a window, which behaves as a large, soft, directional source — a free "softbox" installed in nearly every room. Softest and most shaping when the subject stands close and beside the glass; a north-facing window (northern hemisphere) gives soft, indirect, consistent light all day.

Work-for-hire — An arrangement (varying by contract, employment status, and jurisdiction) in which ownership of what you create belongs to the party who hired you, rather than defaulting to you as creator; the copyright-side view of the §38.2 ownership clause. (§38.5)

Wrapper / container (delivery) — The file type you export into, named by its extension (.mp4, .mov, .mxf), that packages the encoded video, audio, and metadata into one shippable object. On delivery the choice is mostly about compatibility: .mp4 to ship (universal), .mov for ProRes masters, .mxf only when a broadcast spec demands it. Chapter 3's "container," seen from the delivery end.

Z

Zebras — An in-camera or on-monitor overlay that paints animated diagonal stripes onto any part of the live image brighter than a set threshold. Commonly set near 95–100% as a clipping alarm, or around 70% as a skin-tone meter (expose until stripes kiss the cheeks).

Zoom lens — A lens that covers a range of focal lengths in one barrel, chosen with a twist of the ring. Buys speed and flexibility (instant reframing without changing glass), at the cost of usually being heavier, optically more complex, and "slower" (rarely opening past f/2.8).
