Editing

Cross-cutting alternates between two or more lines of action happening in different places, usually at the same time, so each strand builds tension or meaning against the other.

A cutaway briefly leaves the main action for something else — a detail, a bystander, an object elsewhere — then returns, adding information, a joke or a way to hide a cut.

The Kuleshov effect is the finding that viewers read the same neutral face differently depending on the shot cut next to it — food, a coffin, a child — so meaning comes from the edit, not the single shot.

A montage is a sequence of short shots, usually set to music, that compresses time or builds an idea — weeks of training, a relationship, a city waking up — in a minute or two.

A dissolve blends one shot into the next: the first fades out while the second fades in over the same frames, briefly overlapping — often to mark passing time or link two ideas.

Transitions are the ways one shot or scene gives way to the next — the plain cut, dissolve, fade, wipe, match cut and hidden or stylised moves like whip and mask transitions.

In a J-cut the sound of the next shot starts before its picture, so we hear the new scene or speaker a moment before we see it.

A jump cut joins two shots of the same subject from nearly the same angle, so time visibly skips forward and the cut itself becomes noticeable — used for energy, unease or elapsed time.

In an L-cut the sound of a shot continues after the picture has cut to the next one — we still hear a line or a room while already seeing the reaction or the new scene.

A match cut joins two different shots through a shared shape, movement, composition or sound — the bone that becomes a satellite in 2001 — so the cut draws a link between them.

Match on action cuts in the middle of a movement — a door opening, a punch, a glass raised — and continues it in the next shot from another angle, so the cut hides inside the motion.

A smash cut jumps abruptly from one scene to a sharply contrasting one — loud to silent, calm to chaos, a promise to its opposite — for shock or comedy.

A fade gradually brings the picture up from black (fade in) or takes it down to black or another colour (fade out), marking the start or end of a scene or a big jump in time.

A cut is the instant change from one shot to the next with no transition effect — the basic unit of editing, from invisible continuity cuts to jarring jump and smash cuts.

A seamless transition hides the cut inside matching motion, a camera move, a dark object crossing the lens or a shared shape, so two shots play as one continuous action.

A freeze frame holds a single frame on screen so the action stops dead — to end a film, introduce a character, underline a moment or cue narration.

Split screen divides the frame into two or more panels showing different shots at once — two ends of a phone call, parallel actions or perspectives — a signature of Brian De Palma and of 500 Days of Summer's expectations-vs-reality scene.

A trailer is a 1–3 minute promotional cut of a film's best moments — usually a three-act mini-structure of setup, escalation and a button — built from picture, music and sound design to sell the film without spoiling it.

A shot is one uninterrupted run of the camera, a scene is a continuous action in one place and time built from shots, and a sequence is a group of scenes forming one dramatic unit — the three building blocks of film structure.

Editing a dialogue scene means choosing when to show the speaker, the listener or both, and where to cut on lines, pauses and reactions so the conversation keeps its rhythm and subtext.

An eyeline match cuts from a character looking off-screen to what they are looking at, with the gaze direction matched so the audience instantly reads the second shot as their view.

Fast cutting strings together many very short shots in quick succession to create energy, chaos or overload — common in action, trailers and music videos.

In-camera editing means shooting shots in their final order and length, or building transitions physically on set, so the film is effectively cut during the shoot rather than afterwards.

Juxtaposition places two contrasting images side by side — in one frame or across a cut — so their collision creates a meaning neither has alone.

Pacing is how fast a film feels to the viewer — set by shot length, how much happens per scene and how long the edit lets moments breathe.

The rough cut is the first shaped version of the film after the assembly: scenes are trimmed and ordered for story, but pacing, sound, music and effects are still temporary.

A wipe replaces one shot with the next by a moving edge or shape travelling across the frame — a line, a clock hand, a closing iris — a stylised transition famous from Star Wars.

Archival footage is previously shot material — newsreels, home movies, TV broadcasts — cut into a new film as historical evidence, texture or counterpoint, usually keeping the look of its original medium.
