Video scripting glossary

Short definitions of the terms creators, editors and marketers use when planning short-form and long-form videos, each with a practical example. Use it to brief an editor, read analytics or understand why a script is structured the way it is.

Hook
The opening seconds of a video, built to stop the scroll and give the viewer a reason to keep watching. It can be a spoken line, a visual, on-screen text, or a mix.
Example: A cooking video opens on a burnt pan with the line, "I ruined this dish three times before I found the fix."
Related: Hook rate, Cold open, Re-hook
Retention rate
The percentage of viewers still watching at a given point in a video, or on average across the whole video. Platforms usually show it as a graph that falls over time.
Example: Your retention graph drops sharply at 0:03 where a logo animation plays, so you cut the logo and start on the first sentence.
Related: Watch time, Completion rate, Re-hook
Pattern interrupt
A sudden change in visuals, sound, or pacing that breaks a viewer's autopilot and pulls their attention back to the video.
Example: Halfway through a talking-head explanation, you cut to a close-up with a quick sound effect and a new camera angle.
Related: Hook, Jump cut, Re-hook
Open loop
A question, promise, or unfinished idea that you raise early and resolve later, giving viewers a reason to stay until the answer arrives.
Example: "There's one caption setting that makes most videos look amateur. I'll show you at the end."
Related: Payoff, Hook, Retention rate
CTA (call to action)
A direct prompt telling viewers what to do next, such as follow, comment, save, or visit a link. It works best when it is a single, specific ask.
Example: At the end of a editing tutorial you say, "Comment 'checklist' and I'll send you the one I use."
Related: Payoff, On-screen text, Completion rate
Watch time
The total amount of time people spend watching a video, or all your videos. It reflects both how many people watch and how long each one stays.
Example: A 20-second video watched 100 times at an average of 10 seconds each adds up to 1,000 seconds of watch time.
Related: Retention rate, Completion rate, Loop
B-roll
Supplementary footage that you cut to while the main footage or audio continues. It adds context, variety, and visual interest.
Example: While you describe your morning routine on camera, the edit cuts to clips of coffee pouring and a laptop opening.
Related: A-roll, Voiceover, L-cut
A-roll
The primary footage of a video, usually the speaker or main subject on camera delivering the core message.
Example: You film yourself explaining three lighting tips straight to camera, then add other clips on top as B-roll.
Related: B-roll, Jump cut, J-cut
Jump cut
A cut between two clips of the same subject and framing that creates a visible skip in time. Creators use it to remove pauses and tighten pacing.
Example: You trim every breath and "um" from a talking-head clip so each sentence lands right after the last one.
Related: A-roll, Pattern interrupt, Beat
Caption safe zone
The part of a vertical frame that stays clear of app interface elements like usernames, buttons, and platform captions. Text placed inside it stays readable.
Example: You move your subtitles up from the very bottom of the frame so the platform's caption and like button don't cover them.
Related: On-screen text, Thumbnail, CTA (call to action)
J-cut
An edit where the audio of the next clip starts before its video appears. The viewer hears what's coming before seeing it.
Example: You hear a keyboard clacking over your face on camera, then the picture cuts to the laptop screen.
Related: L-cut, A-roll, B-roll
L-cut
An edit where the video switches to the next clip while the audio from the previous clip keeps playing. It's common when cutting to B-roll during speech.
Example: You keep talking about a product while the picture cuts to a close-up of the product itself.
Related: J-cut, Voiceover, B-roll
Re-hook
A second hook placed mid-video to win back viewers whose attention is starting to drift. It often introduces a new question or a surprising turn.
Example: Around the midpoint you say, "But here's the part almost everyone gets wrong," and cut to a new visual.
Related: Hook, Retention rate, Open loop
Payoff
The moment a video delivers on what the hook or open loop promised. A clear payoff makes the video feel worth finishing.
Example: After teasing a faster export method, you finally reveal the exact setting and show the time difference on screen.
Related: Open loop, Hook, Punchline
Beat
The smallest unit of a script or story: one idea, action, or shift, usually paired with a single visual. Short videos are often planned as a sequence of beats.
Example: Your 30-second script has six beats: hook, problem, step one, step two, result, and CTA.
Related: Storyboard, Rule of three, Jump cut
Voiceover
Narration recorded separately from the on-camera footage and laid over visuals. It lets you explain things the picture alone can't show.
Example: You record a voiceover for a screen recording of your editing workflow and add B-roll of your desk.
Related: B-roll, On-screen text, L-cut
On-screen text
Words displayed over a video, including captions, titles, labels, and key phrases. It helps viewers who watch without sound and reinforces the main point.
Example: You show "3 mistakes to avoid" as a title in the first second, then label each mistake as you mention it.
Related: Caption safe zone, Hook, CTA (call to action)
Loop
A video built so the ending flows back into the beginning, making a replay feel seamless. Viewers may watch again without noticing the restart.
Example: Your last spoken words complete the sentence you started in the opening line, and the final frame matches the first.
Related: Watch time, Completion rate, Callback
Completion rate
The percentage of views in which the viewer watches the video through to the end. It is easier to raise on shorter videos.
Example: You cut a 45-second video to 28 seconds by removing a slow explanation, aiming for more viewers to reach the ending.
Related: Retention rate, Watch time, Loop
Hook rate
The share of people who keep watching past the first few seconds after the video appears. Definitions vary by platform, but it is often views past 3 seconds divided by impressions.
Example: You test two openings of the same video and keep the one with the higher hook rate.
Related: Hook, Retention rate, Thumbnail
Thumbnail
The still image that represents a video in a feed, profile grid, or search result. On short-form platforms it may be a chosen frame or an uploaded cover.
Example: You pick a frame with your face clearly visible and add a three-word title inside the caption safe zone.
Related: Hook rate, On-screen text, Caption safe zone
Cold open
Starting a video in the middle of the action or with its most interesting moment, before any intro, greeting, or title.
Example: A travel clip begins with you mid-jump off a pier, then rewinds to explain how you got there.
Related: Hook, Payoff, Pattern interrupt
Punchline
The final line or moment of a joke or point, which delivers the twist or surprise the setup was building toward.
Example: After describing a perfectly organized editing folder, you cut to your real desktop covered in files named "final_final2".
Related: Payoff, Rule of three, Beat
Rule of three
A writing pattern that groups items in threes. The first two set a pattern and the third completes or subverts it, which feels satisfying and memorable.
Example: "Wake up, make coffee, and open 47 browser tabs."
Related: Punchline, Beat, Callback
Callback
A later reference to something said or shown earlier in the same video. It rewards viewers who stayed and ties the script together.
Example: You joke about your messy desk in the opening, then end by revealing it's still messy after the "organized" makeover.
Related: Loop, Punchline, Rule of three
Storyboard
A sequence of sketches or frames that plans each shot of a video before filming. It helps you decide framing, order, and pacing in advance.
Example: You sketch eight simple frames for a 20-second video, noting the shot type and any on-screen text for each.
