Short-Form Video Glossary

Plain definitions of the editing, format, and platform terms behind short-form video.

Shots & framing

A-rollA-roll is the primary footage in a production, typically the main interview, on-camera narration, or principal action that carries the story forward.B-rollB-roll is supplemental footage intercut with the primary footage (A-roll) to add visual context, cover edits, and maintain viewer interest.Close-upA close-up is a shot that fills most of the frame with a single subject, typically framing a person from the shoulders to the top of the head.Establishing shotAn establishing shot is a wide or extreme-wide shot placed at the opening of a scene to show the audience where and sometimes when the action takes place.HeadroomHeadroom is the space between the top of a subject's head and the top of the video frame.Medium shotA medium shot frames a person from roughly the waist up, splitting the difference between a close-up and a wide shot.Over-the-shoulder shotAn over-the-shoulder shot places the camera just behind one person's head and shoulder while focusing on the person facing them, so both subjects appear in frame.POV shotA POV shot positions the camera to represent exactly what a specific character or subject is seeing, giving the audience a first-person view of the scene.Rule of thirdsThe rule of thirds is a composition guideline that divides the frame into nine equal parts using two horizontal and two vertical lines, then places the main subject along those lines or at their four intersection points.Talking headA talking head is a shot framing a person from roughly the shoulders or chest up while they speak directly to the camera.Two shotA two shot frames two people within the same shot, whether side by side or at different depths in the frame.Wide shotA wide shot frames the full figure of a person or object within its surroundings, giving the viewer a clear sense of location, scale, and spatial context.

AI video editing

AI avatarAn AI avatar is a synthetic, human-like digital character generated and animated by AI, capable of speaking, gesturing, and delivering scripted content on screen.AI B-rollAI B-roll is supplementary footage generated or automatically matched by AI to accompany a primary video, based on the script or narration.AI captionsAI captions are automatically generated subtitles produced by speech-recognition software that transcribes and timestamps spoken audio across a video.AI music generationAn AI music generator composes original audio tracks from a text prompt or a set of parameters such as mood, style, and tempo, producing royalty-free music without requiring musical skills.AI voiceoverAn AI voiceover is a narration track generated by a text-to-speech model, producing a human-sounding voice from a typed script without a recording session.Auto reframeAuto reframe is an AI editing feature that automatically changes a video's aspect ratio while keeping the main subject centered in the new frame.Auto-clippingAuto-clipping is an AI feature that scans a longer video, identifies the most engaging or relevant moments, and exports them as shorter, trimmed clips ready for publishing.Background removalAI video background removal uses machine learning to isolate the subject in each frame of a video and remove or replace the surrounding background, without requiring a physical green screen.DubbingDubbing is the replacement of the original spoken audio in a video with a new voice track, most often in a different language.Eye contact correctionEye contact correction is an AI video effect that adjusts a speaker's gaze in the final footage so they appear to be looking directly at the camera, even when they were reading a script or looking at a second screen during recording.Filler word removalFiller word removal is an automated editing process that uses speech recognition to detect verbal hesitations such as 'um,' 'uh,' and 'like' in a recording and removes them from the audio and video tracks.Highlight detectionHighlight detection is an AI process that analyzes video content to automatically flag the moments most likely to hold audience attention, such as clear takeaways, strong opinions, or emotionally charged language.Lip syncLip sync is the alignment of visible mouth movements in a video with the spoken audio, so the two appear to originate from the same person at the same moment.Scene detectionScene detection is the automated process of identifying cut points and scene boundaries within a video file by analyzing changes in color, lighting, and visual content between consecutive frames.Script to videoScript-to-video is an AI workflow that takes a written script and produces a complete video draft, adding visuals, voiceover, subtitles, and music automatically.Silence removalSilence removal is an automated editing feature that detects and trims gaps and dead air from an audio or video recording.Smart cutA smart cut is an automated editing feature that scans a video recording, identifies sections with no speech or with filler words, and removes them in a single action.Text to videoText-to-video is an AI process that generates video footage from a written description, producing moving images without any filming or traditional animation.Text-based editingText-based editing is a video editing approach where the software generates a transcript of the video and lets the editor work on that transcript like a document.Video summarizationVideo summarization is an AI process that analyzes a video's content and compiles a condensed version, either as a short text summary with key points and timestamps or as a shorter video made from the most important segments.Video upscalingVideo upscaling is the process of increasing a video’s resolution, converting low-resolution footage to a higher pixel count.Voice cloningVoice cloning is an AI process that analyzes a short audio sample of a person's voice and creates a synthetic replica that captures their tone, pitch, and speech patterns.

Audio

Audio duckingAudio ducking is a technique that automatically lowers the volume of background music or ambient sound whenever a primary audio track, such as dialogue or voiceover, becomes active.Beat syncBeat sync is the editing practice of aligning cuts, transitions, or visual changes to the beats of a music track so that the rhythm of the edit mirrors the rhythm of the audio.Noise reductionNoise reduction is the process of identifying and removing unwanted background sounds from an audio recording, such as hum, hiss, wind, or room echo.Room toneRoom tone is the ambient sound present in a location when no intentional noise is being made, capturing the acoustic character of the space, including hums, air movement, and distant sounds.Sound designSound design is the craft of building the complete audio experience of a video by selecting, creating, and combining dialogue, music, sound effects, ambient noise, and any other audio elements.Sound effectsSound effects are audio elements, distinct from dialogue and music, added to a video to create a specific impression, reinforce what is happening on screen, or establish atmosphere.Sync soundSync sound is audio recorded at the same time as the video footage it accompanies, so that the sound and picture are aligned in time from the start.VoiceoverA voiceover is narration recorded by a speaker who does not appear on camera, played over video footage to explain, comment on, or tell a story about what viewers are seeing.

Captions & on-screen text

Auto captionsAuto captions are text captions generated automatically by speech recognition software, synchronized to the audio track without manual transcription.Caption burn-inCaption burn-in is the process of permanently rendering caption text into the video frames at the pixel level, producing what are also called open captions or hard-coded captions.Closed captionsClosed captions are a text track synchronized to a video's audio that viewers can turn on or off through the player's settings.Kinetic typographyKinetic typography is an animation technique in which text moves, transforms, or changes in sync with audio or a visual rhythm to communicate an idea or tone.Lower thirdA lower third is a text or graphic overlay positioned in the lower portion of the video frame, used to display identifying information such as a person's name, title, or location.Open captionsOpen captions are text permanently embedded into the video image so they are always visible and cannot be turned off by the viewer.SRT fileAn SRT file (SubRip Subtitle file) is a plain text file that pairs subtitle text with start and end timecodes, telling a video player when to display each line of text on screen.SubtitlesSubtitles are lines of text displayed on screen that represent spoken dialogue, primarily to translate content from one language into another.Title cardA title card is a screen that displays printed text within a video, used to convey information such as a date, location, speaker name, or narrative context.

Platform features

Capcut templateA CapCut template is a pre-built video project that includes preset transitions, effects, music timing, and sometimes text overlays, so a creator can produce a finished short-form video by swapping in their own clips or photos.CarouselA carousel is a social media post format that packages multiple images, videos, or a mix of both into a single post that viewers swipe or click through.For you pageThe For You Page (FYP) is TikTok's default home feed, a personalized stream of videos selected by the platform's recommendation algorithm based on signals like watch time, interactions, and content type.Going liveGoing live is the act of broadcasting video in real time to followers on a social media platform, with viewers able to comment and react as the stream happens.HashtagA hashtag is a word or phrase preceded by the # symbol that categorizes a post so it appears in search results and topic feeds for that term.ReelsReels are Instagram's short-form video format, supporting multi-clip vertical videos with music, effects, voiceovers, and other creative tools.ShadowbanA shadowban is when a platform quietly reduces a creator's content visibility, limiting reach on discovery feeds, hashtag pages, or recommendations, without notifying the creator.ShortsYouTube Shorts is YouTube's short-form video format, consisting of vertical videos up to 3 minutes long that are accessible through a dedicated Shorts feed on the YouTube app and website.Spark adsSpark Ads is a TikTok ad format that lets advertisers promote an existing organic post as paid media, so all engagement on the ad, including likes, comments, shares, and follows, accumulates on the original post.StoriesStories are short-lived posts on platforms like Instagram and Snapchat that disappear after 24 hours and display in a vertical, full-screen format separate from a creator's main profile or feed.Text-to-speechText-to-speech (TTS) is a feature in video editing apps that converts written text into a synthesized spoken voice, which can be added to a video as a voiceover.The algorithmThe algorithm, in the context of short-form video platforms, refers to the recommendation system that decides which videos each user sees in their personalized feed.TikTok shopTikTok Shop is an e-commerce feature built into TikTok that lets sellers list products and buyers complete purchases without leaving the app.TrendA trend on social media is a piece of content, a behavior, a sound, or a hashtag that is spreading rapidly across the platform at a given moment, typically surfaced by the algorithm to users who engage with related content.

Motion & effects

Chroma keyChroma key is a compositing technique that removes a specific color, typically green or blue, from a video clip and replaces it with a different image or footage.Color correctionColor correction is the technical process of adjusting a clip's exposure, white balance, and color balance to produce an accurate and consistent image that matches how the scene actually looked.Color gradingColor grading is the post-production step of making deliberate creative adjustments to a video's color, contrast, and tone to establish a particular visual mood or aesthetic.Green screenA green screen is a solid green backdrop filmed behind a subject so that the background can be replaced with different footage or imagery in post-production using the chroma key technique.Ken Burns effectThe Ken Burns effect is a post-production technique that applies slow panning and zooming movement to a still image, creating the illusion that a camera is moving within the frame.KeyframeA keyframe is a marker on a video timeline that records the value of a property, such as position, scale, or opacity, at a specific moment.LUTA LUT, or Look-Up Table, is a file that remaps the color and tone values of footage from one set of values to another, functioning as a reusable color grade that can be applied in a single step.MaskingMasking is a video editing technique that defines a specific region of the frame using a shape or drawn path, allowing effects, color adjustments, or compositing to be applied only within that area.OverlayAn overlay is a video, image, or graphic element placed on a separate layer above the base footage in an editing timeline.Punch-inA punch-in is a tighter framing created by digitally cropping or enlarging an existing shot, so the viewer sees a closer view without a separate close-up having been filmed.Slow motionSlow motion is a technique that makes action appear to move more slowly than it did in reality by recording footage at a higher frame rate than it will be played back.Speed rampA speed ramp is an editing technique where the playback speed of a single clip changes continuously within that clip, shifting between normal speed, slow motion, and fast motion.Time-lapseTime-lapse is a technique where individual frames are captured at a much slower rate than they will be played back, so that when the footage runs at normal speed, events appear to happen far faster than they did in reality.

Cuts & transitions

Cross dissolveA cross dissolve is a transition in which the outgoing clip gradually fades to transparency while the incoming clip simultaneously fades to full visibility, so both images are briefly visible at once.CutawayA cutaway is a shot inserted into the main footage that briefly shows something other than the primary action, after which the edit returns to the original shot.FadeA fade is a transition to or from a solid color, most often black, where the image gradually darkens until nothing is visible (fade out) or brightens from nothing to a full image (fade in).Hard cutA hard cut is an instantaneous switch from one shot to the next with no dissolve, fade, or other visual treatment applied to the transition.J-cutA J-cut is an edit where the audio from the next shot begins before the picture cuts to it, so the viewer hears the incoming scene's sound while still watching the current footage.Jump cutA jump cut is an edit that removes a section from the middle of a continuous shot and joins the remaining pieces together, making the subject appear to lurch forward in time.L-cutAn L-cut is an edit where the audio from one shot continues playing after the picture has already cut to the next shot, so the viewer hears the first scene's sound while watching new visuals.Match cutA match cut is a transition between two shots that are linked by a shared visual element, action, sound, or theme, so the viewer's eye carries smoothly from one scene to the next.MontageA montage is a sequence of short shots edited together to condense time, summarize a process, or create meaning through the juxtaposition of images that would not carry the same weight shown individually.Smash cutA smash cut is an abrupt, jarring transition from one scene to a drastically different one, timed for deliberate emotional, comedic, or dramatic effect.Whip panA whip pan is a camera movement where the lens rotates horizontally so fast that the image blurs, and that blur is used to disguise a cut between two separate shots.WipeA wipe is a transition in which the incoming shot moves across the frame in a specific direction or shape, replacing the outgoing shot as it travels.

Short-form editing trends

Freeze frameA freeze frame is an editing technique where a single video frame is held as a still image for an extended moment, created by duplicating that frame in the timeline.Glow-up transitionA glow-up transition is a before-and-after video format that shows a significant personal transformation, typically in appearance, confidence, or lifestyle.Invisible cutAn invisible cut is an edit where the transition between two shots is so closely matched in action, composition, and audio that the viewer does not perceive the cut at all.Parallax effectThe parallax effect is an editing technique that simulates depth by separating a flat image into foreground and background layers and moving each at a different speed, so closer elements appear to travel faster than distant ones.Seamless transitionA seamless transition is a motion-based effect, such as a whip pan or cross dissolve, that bridges two clips so the cut between them is hard to spot.Shake transitionA shake transition is a brief frame-vibration effect placed between scenes, timed to a music beat through rapid crop and zoom adjustments.Snap zoomA snap zoom, also called a crash zoom, is an abrupt, very rapid zoom into a subject that is executed in post-production or in-camera, producing a punchy, almost handheld-jitter quality.Text revealA text reveal is an animation where text appears on screen progressively through a wipe, slide, or mask, with words or lines landing one piece at a time.Velocity editA velocity edit is a technique where the playback speed of a single clip is varied at different points, speeding up in some sections and slowing down in others.Zoom transitionA zoom transition connects two clips by zooming into the end of the first shot and zooming back out at the start of the next, so the cut feels like a single continuous push through space.
