Watch a breakdown, read a tutorial, talk shop with another creator, and the jargon flies past: L-cut, match cut, MacGuffin, chiaroscuro. Knowing these words is not pedantry — naming a technique is what lets you reach for it on purpose instead of by feel. This is a working glossary of the terms that actually come up when you dissect real videos, grouped into nine areas, each with what it is and when to use it.
How to read this: terms are grouped into nine areas — editing, shot size & angle, camera movement, composition, lighting, color, sound, narrative, and psychology. Each entry gives a one-line meaning and when to use it. Not exhaustive — only the terms that actually come up when you dissect footage, write a script, or talk to an editor.
1. Editing & Transitions: Start with J-Cut and L-Cut
Short video is 99% hard cuts, but which frame you cut on is the difference between smooth and clumsy. The first thing worth mastering here is the split edit — where sound and picture do not cut on the same frame — namely the J-cut and the L-cut.
Term
What it is
When to use it
J-cut (audio leads)
The next shot’s audio comes in before its picture
To smooth a transition or foreshadow the next scene with sound
L-cut (audio trails)
The picture has cut away but the previous shot’s audio keeps playing
Cut to the listener’s reaction while the speaker is still talking
Match Cut
Hard-cut two shots that share a shape, composition, or motion
Time/space jumps, wardrobe swaps, transformations
Match on Action
Cut mid-action, at the peak of a gesture
The brain fills in continuity; the cut goes unnoticed
Jump Cut
Same framing, a jump forward in time
Compress a process, add pace, create unease
Freeze Frame
The image holds on a single frame
Comedic endings; nail the funniest/strongest frame as a memory hook
Speed Ramping
Sudden speed change within one shot
"Fast-slow-fast" punch; slow-mo to enlarge a payoff
Reaction Shot
Shoot the person absorbing the emotion, not the event
Cheapest empathy device — a face tells viewers how to feel
Mnemonic: J = audio arrives early (hook to the left), L = audio lingers (foot extends right) — the names are literally the shape the exposed audio block makes on the editing timeline. A J-cut is also called a "sound bridge," the most common trick for smoothing a hard cut.
2. Shot Size & Angle: How Close, From What Height
Shot size is how close; angle is from what height. Short video loves skipping the middle sizes for impact, and uses low/high angles to encode who holds power.
Term
What it is
When to use it
Shot sizes (wide → ECU)
Six distances from "see the room" to "see the eyes"
No two adjacent shots share a size; the pre-payoff shot is one size wider
Size Jump
Cut straight from wide to extreme close-up, skipping medium
For impact; the middle sizes are the enemy of pace
Low Angle
Shooting upward at the subject
Power, dominance, heroism (the boss enters)
High Angle
Shooting downward at the subject
Smallness/scrutiny; a CCTV top-down is a public-humiliation gag
Dutch Angle
The camera is deliberately tilted
Imbalance, danger, disorientation
POV
The lens is the character’s eyes
Immersion; disguises a staged clip as a candid grab
Foreshortening
An object facing the lens looks compressed
Fist/muzzle at the lens — aggression, puts you in the victim’s seat
3. Camera Movement
Whether and how the camera moves. One counterintuitive rule: with AI or low-budget shoots, lock the camera and let the subject move toward it or objects shift — it is steadier and hides flaws better than actual moves.
Light from behind creates a gold edge or silhouette
Elevate an ordinary person into an icon
Chiaroscuro
Strong light/dark contrast to model volume (from painting)
Bind to power, crisis, political darkness
Practical Light
A real in-frame source (lamp, neon, phone screen)
Use as a state tag — cold screen = illicit, warm lamp = safe
Golden / Blue Hour
Warm gold before sunset / cool blue after
A free filter for healing, beautiful footage
6. Color
Term
What it is
When to use it
Color Temperature
Warm (orange) vs. cool (blue)
The mood engine, and a way to zone the story (warm = memory, cool = now)
Complementary Colors
Two opposite colors side by side (teal & orange)
To pop the subject, give the background its complement
Single Saturated Anchor
A desaturated base with one saturated accent
Lock the focal point (the red scarf in the snow)
Color Grading / LUT
Unify the look in post
A unified high-contrast grade makes mixed-source edits feel seamless
7. Sound
Term
What it is
When to use it
Diegetic / Non-diegetic
Sound characters can hear / cannot (music, narration)
Blending or offsetting them reads as sophisticated
Foley
Everyday sound effects rebuilt in post
Sound is the anchor of realism — the faker the image, the realer the Foley must be
Sound Bridge
Carry sound across a cut to link two scenes (a J-cut)
To smooth a hard cut
Asynchronous Sound
Subtitles/lines and the audio deliberately say different things
Trade the viewer’s inference for information density
Audio Cut
Kill music and ambience right before the payoff
The loudest beat is the one where you remove the music
Beat Matching
Land action accents on the beat or the lyric syllable
Hitting the freeze frame of a move feels best
8. Narrative Structure
Term
What it is
When to use it
Hook
The unresolved gap in the first 0–3s that keeps people watching
The first three seconds decide completion
MacGuffin
A goal object that drives the plot but barely matters and is never explained
Sustain suspense to hold completion
Chekhov’s Gun / Setup-Payoff
An element shown early must pay off later
Plant foreshadowing; build the foundation for a twist
Dramatic Irony
The audience knows the truth before the character does
Creates "I know, he doesn’t" tension and tears
Cold Open / In Medias Res
Cut the setup; open on conflict or the result
Drop the viewer mid-scene, backfill later
Zeigarnik Effect
Unfinished things are remembered better
End on the brink of the payoff to convert completion into a follow
Breaking the Fourth Wall
A character looks at or talks to the lens
Open to hold viewers; close to make them "jurors" and fire up comments
Kuleshov Effect
The same face next to different shots reads as different emotions
Explains why reaction shots and indirect characterization work
9. Psychology & Virality: Why It Works
Term
What it is
When to use it
Uncanny Valley
The unease when something is almost-but-not-quite human
AI clips dodge it with non-human characters, cuteness, micro-expressions
Supernormal Stimulus
Push a signal past its natural extreme
Trim a dog into a perfect circle to trigger the cuteness instinct
Barnum Effect
Vague, universal statements everyone reads as personal
"Are you waiting on a message lately?"
Loss Aversion
Fear of losing outweighs desire to gain
"Skip this and stay poor" beats "grab this and get rich" for engagement
Social Proof
Let other people’s reactions, queues, crowds vouch for you
More credible than praising yourself
Von Restorff (Isolation) Effect
The odd one out in a uniform set is remembered most
One red in the cool palette; one cute thing amid the serious
The fastest way to make these terms stick is to spot them in real footage. Paste any video link you like into VideoLens and it auto-extracts the shot-by-shot structure, hook types, and retention points — you will watch this jargon show up on screen, one term at a time. Reading a glossary against a real breakdown beats memorizing a table.
