How This Glossary Is Organized
Terms are grouped into ten categories, ordered roughly from modern to foundational. AI and agentic editing come first, because that's what most people are searching for in 2026. Then cutting, footage, captions and audio, color, formats and export, social platforms, workflow, motion and effects, and analytics. Within each category, terms run from most to least common.
AI and Agentic Editing Terms
AI video editing: Using artificial intelligence (speech recognition, computer vision, language models) to automate editing tasks like cutting, captioning, and reframing. See our beginner's guide.
Agentic editing: A workflow where an AI agent autonomously plans and executes multi-step edits from a natural language goal, rather than assisting one task at a time.
Natural language editing: Editing by typing or speaking instructions ("remove all silences") instead of manipulating a timeline directly.
Prompt-driven workflow: A production process in which prompts to an AI, not manual operations, are the primary way edits get made.
Automated editing: Software applying predefined or AI-planned editing operations without human intervention per edit.
Visual understanding: A model's ability to recognize faces, objects, scenes, actions, and composition within footage. It's the perceptual foundation of AI editing.
Content-type detection: AI classification of footage (podcast, tutorial, vlog, keynote) so the editor can apply genre-appropriate treatment automatically.
Scene detection: Automatically finding cut points where the visual content changes: shot boundaries, location changes, slide transitions.
Speaker detection: Also called speaker diarization. Identifying who is speaking when, which enables automatic multicam switching and per-speaker captions.
Speech-to-text (ASR): Automatic speech recognition. Converts spoken audio into time-coded text, the substrate for captions and text-based editing.
Silence removal: Automatically cutting dead air and long pauses from a recording.
Filler word removal: Automatically detecting and cutting "um," "uh," "like," and other verbal filler.
Highlight clip generation: AI scoring of a long recording to find its most engaging moments and cut them into standalone short clips.
Generative AI for video: Models that create new video, imagery, music, or sound effects from text descriptions, used for B-roll and fill.
Text-to-video: Generating video footage directly from a written prompt.
Text-based editing: Editing video by editing its transcript. Delete a sentence, and the corresponding footage is cut.
AI agent: Software that pursues a goal by planning, acting, observing results, and iterating. In editing, it's the entity that executes your creative direction. See agentic video editing explained.
Multimodal model: An AI model that processes multiple input types (video frames, audio, text) at once. It's what lets an editor "watch" footage.
Auto-reframe: AI cropping that keeps the subject centered while converting between aspect ratios.
Virality score: A predicted engagement rating AI tools assign to candidate clips when ranking highlights.
Cutting and Timeline Terms
Timeline editor: The classic editing interface, with horizontal tracks holding clips in time order.
Cut: Any instantaneous transition between two shots. The atomic unit of editing.
Rough cut: The first assembled version of a video, with correct order and content but unpolished pacing.
Fine cut: A later revision with tightened pacing and near-final timing.
Final cut (picture lock): The finished edit. No further changes to timing or structure.
Jump cut: A cut between two similar framings of the same subject, creating a visible "jump." Stylistic in vlogs, an artifact everywhere else.
J-cut: Audio from the next shot starts before its picture appears.
L-cut: Audio from the current shot continues over the next shot's picture.
Match cut: A cut linking two shots through matching composition or action.
Cutaway: A shot inserted away from the main action (a reaction, an object), often used to hide edits.
Hard cut: A plain cut with no transition effect.
Trim: Adjusting a clip's start or end point.
Ripple edit: A trim that shifts everything after it to close or open the gap.
Roll edit: Moving the boundary between two adjacent clips without changing total duration.
Slip edit: Changing which portion of a source clip plays without moving the clip's position.
Slide edit: Moving a clip along the timeline while its neighbors adjust around it.
Razor / blade tool: The tool that splits a clip in two at the playhead.
In point / out point: Markers defining the start and end of a selection in source footage or on the timeline.
Three-point editing: The classic technique of using any three of source in/out and timeline in/out to place a clip precisely.
Playhead: The moving indicator that shows the current time position on the timeline.
Footage and Production Terms
A-roll: Primary footage. The interview, the talking head, the main performance.
B-roll: Supplementary footage cut over A-roll to illustrate, pace, or hide edits.
Master shot: A wide take covering an entire scene, used as the structural backbone.
Coverage: All the angles and shot sizes captured for a scene.
Take: One recorded attempt at a shot or line.
Dailies / rushes: Raw footage reviewed right after shooting.
Room tone: The ambient "silence" of a location, recorded to smooth audio edits.
Scratch audio: Temporary audio used during editing, replaced before delivery.
Slate / clapperboard: The marked board clapped on camera to sync audio and label takes.
Talking head: A framed shot of a person speaking to camera. The staple of podcasts and interviews.
Multicam editing: Editing synchronized footage from multiple cameras, switching angles on one timeline.
VOD: Video on demand. Also shorthand for an archived livestream recording.
Log footage: Flat, low-contrast footage that preserves dynamic range for grading.
Screen recording / screencast: Captured screen output, standard for tutorials and demos.
Caption, Subtitle, and Audio Terms
Auto-generated captions: Captions produced by speech recognition rather than typed by hand. Modern systems handle dozens of languages.
Video transcription: Converting all speech in a video to text, with or without timestamps.
Closed captions (CC): Captions the viewer can toggle, delivered as a separate track or file.
Open captions (burned-in): Captions rendered permanently into the video image.
Subtitles: Text translating or transcribing dialogue. Distinct from captions, which also describe non-speech sound.
SDH: Subtitles for the deaf and hard of hearing. They include speaker labels and sound descriptions.
SRT / VTT: The two dominant subtitle file formats: plain-text time-coded blocks (SRT) and the web-native WebVTT (VTT).
Karaoke captions: Word-by-word highlighted captions synchronized with speech, dominant in short-form video.
Caption grouping: How transcribed words are broken into on-screen lines. Modern systems break at natural pauses. See how Loopdesk rebuilt multilingual captions.
Speaker diarization: See speaker detection. Attributing each spoken segment to the right person.
Ducking: Automatically lowering music volume while someone speaks.
Voiceover (VO): Narration recorded over footage.
ADR: Automated dialogue replacement. Re-recording dialogue in post.

Normalization: Adjusting audio to a target level.
LUFS: Loudness Units Full Scale. The loudness standard platforms use (YouTube targets about -14 LUFS).
Noise reduction: Removing hiss, hum, and background noise from audio.
Voice isolation: AI separation of speech from background sound.
Color Terms
Color grading: The creative shaping of a video's color and tone. Its "look."
Color correction: The technical fix that comes first: neutral whites, accurate skin tones, matched shots.
LUT: Lookup table. A preset transformation that maps colors to a new look in one step.
White balance: Adjusting color temperature so whites read as white.
Exposure: Overall image brightness.
Contrast: The spread between an image's darkest and brightest values.
Saturation: Color intensity.

Frequently Asked Questions
What are the most important video editing terms for beginners?
Start with ten: timeline, cut, rough cut, B-roll, transition, keyframe, aspect ratio, bitrate, captions, and export preset. Those cover 90% of what tutorials assume you know. From there, learn the AI vocabulary (agentic editing, silence removal, auto-reframe), because that's where the tooling is heading.
What is the difference between video editing terms and video editing jargon?
Terms are the shared technical vocabulary (codec, LUT, J-cut). Jargon is the informal shorthand editors use around them (picture lock, "gate check," "punch in"). This glossary covers both, and flags informal usage where it matters.
How many video editing terms are in this glossary?
Over 150 terms across ten categories: AI and agentic editing, cutting and timeline, footage and production, captions and audio, color, formats and export, social platforms, workflow and business, motion and effects, and analytics.
