Know These Terms: The Film and TV Editor Glossary
If you think you know editing, then you should know all these definitions.

‘Bohemian Rhapsody’
What amazes me about film and TV editors is how much jargon they have memorized. There are so many different cuts, keyboard tricks, and ideas. And the best ones make it look so easy and speak it so fluently that I always feel a step behind.
That's why I assembled this list of terms you should know if you're an editor or talking to an editor.
These should keep you up to speed and allow you to have conversations about scenes and choices in an educated manner.
Let's dive in.
The Editor Glossary
Editing Without Borders: Sustaining Creative Excellence RemotelyCredit: Skye StudiosI. The Cutting Room Basics
The fundamental language and tools used to organize and build a project.
- Non-Linear Editing (NLE): Modern digital editing software (like Premiere Pro, DaVinci Resolve, or Avid) that allows editors to access any frame of video instantly and non-destructively, meaning the original files are never altered.
- The Timeline: The heart of the NLE. It is a visual, horizontal representation of your project where video and audio clips are arranged in chronological order.
- Dailies (or Rushes): The raw, unedited footage captured during a day of filming. Editors review these immediately to ensure there are no technical glitches or performance issues before the sets are struck.
- Assembly Cut: The "fat cut" or first pass. All scripted scenes are placed in order. It is often much longer than the final film and is used to check the basic logic and structure of the story.
- Rough Cut: A refined version of the assembly where the editor begins to address pacing and performance. It looks like a movie, but it lacks final sound design, visual effects, and color grading.
- Fine Cut: The version where every frame is meticulously polished. Once the director and producers approve this, the film reaches "Picture Lock," meaning no further timing changes can be made.
- Source vs. Program Monitor:
- Source: The window used to preview raw clips and select specific "In" and "Out" points.
- Program: The window that displays the sequence currently being built on the timeline.
II. Types of Cuts & Transitions
Transitions are the "punctuation" of film, dictating how the audience perceives the flow of time and space.
- Hard Cut: The most common transition; one shot instantly replaces another.
- Jump Cut: A cut between two shots of the same subject that are taken from nearly identical camera positions. It makes the subject appear to "jump" forward in time and is often used to show agitation or the passage of long periods.
- Match Cut: A transition that joins two shots with similar compositions, shapes, or movements. It creates a strong metaphorical or logical link between two different scenes.
- Cutting on Action: A technique where the editor cuts from one angle to another while the subject is in motion (e.g., someone starting to sit down). The movement masks the cut, making it feel invisible.
- L-Cut & J-Cut (Split Edits): * J-Cut: You hear the audio of the next shot before you see it.
- L-Cut: The audio from the current shot continues into the next visual shot.
- Why use them? They make dialogue feel natural and fluid by mimicking how humans look around during a conversation.
- Cross-Cutting (Parallel Editing): Cutting between two or more lines of action occurring simultaneously in different locations (e.g., a phone conversation or a chase scene).
- Smash Cut: A sudden, jarring transition designed to surprise the audience—often moving from a very quiet scene to a very loud one.
III. Narrative, Pacing & Composition
The "Art" of the edit. This is where the editor shapes the performance and the emotional "breath" of the film.
- The Kuleshov Effect: A film theory that demonstrates that viewers derive more meaning from the interaction of two sequential shots than from a single shot in isolation.
- The 180-Degree Rule: A spatial guideline that keeps the camera on one side of an imaginary axis between characters. This ensures that Character A always looks "Right" and Character B always looks "Left," preventing audience disorientation.
- B-Roll: Supplemental footage (landscapes, close-ups of objects, hands moving) used to hide cuts in an interview, provide context, or add visual interest to the primary footage (A-Roll).
- Continuity: The process of ensuring that details stay consistent from shot to shot (e.g., a character’s cigarette being the same length, or their hair being tucked behind the same ear).
- Pacing: The rhythm of the film. High-intensity scenes often have "fast" pacing (many short cuts), while emotional or atmospheric scenes have "slow" pacing (long, lingering takes).
- Reaction Shot: A cutaway to a character’s face to show their silent emotional response to what another character is saying or doing. This is often where the most important acting happens.
IV. Technical & Post-Production Specs
The "Science" of the edit. These terms cover the finalization and delivery of the project.
- Color Correction vs. Color Grading:
- Correction: The technical process of making footage look "accurate"—balancing whites, fixing exposure, and matching colors across different cameras.
- Grading: The creative process of applying a "look" or mood (e.g., the desaturated greens of The Matrix or the warm yellows of Mad Max: Fury Road).
- Frame Rate (fps): The number of images displayed per second. Standard cinema is 24fps, while high-motion content (like sports or some TV) is often 30fps or 60fps.
- Codecs & Containers: * Codec: (e.g., H.264, ProRes) The software used to compress the video file so it isn't massive.
- Container: (e.g., .MP4, .MOV) The "wrapper" that holds the video, audio, and metadata.
- Offline vs. Online Editing:
- Offline: Editing with low-resolution "proxy" files to keep the computer running fast.
- Online: Relinking the edit to the original, high-resolution 4K or 8K files for final color and export.
- Room Tone: A recording of the natural "silence" of a location. It is used by editors to bridge gaps in dialogue and create a seamless background noise floor.
- Lower Third: A graphic placed in the lower area of the screen, typically used to display a person’s name and title in documentaries or news.
Hopefully, this all helps your editing journey!
