What is a hook in a video?
Also called Video hook, Opening hookUpdated
From Clyper, the AI clipping tool that turns long videos into captioned vertical clips for TikTok, Reels and Shorts.
Get startedHook, defined
A hook is whatever makes someone keep watching once a video starts: the first line that's said, the first words on screen and the first frame. On TikTok, Reels and Shorts it has a second or two to work, because the next video is one swipe away, and the apps rank videos partly on how many people stay.
Why the hook decides a video's reach
The apps measure the first seconds directly, and say so:
- YouTube Shorts ranks Shorts using the share of viewers who chose to view (rather than swipe away), average view duration and average percentage viewed. The first is decided almost entirely by the hook.
- TikTok says a strong signal, like whether someone watches a longer video from beginning to end, is weighted more than weak ones in the For You feed. Nobody finishes a video they left in the first second.
- Long YouTube videos get an intro score in YouTube Studio: the share of viewers still watching after 30 seconds.
A hook has three layers, and the strongest clips use all three at once:
| Layer | What it is | What it does |
|---|---|---|
| Spoken | The first line said | Makes a promise the clip keeps: a question, a claim, a story already going |
| On screen | A text hook at the top | Tells people with the sound off why to stay |
| Visual | The first frame | A face mid-reaction, movement, something happening, not a pause before it |
The main kinds of hook, with examples
| Kind | Example |
|---|---|
| Curiosity | “Nobody talks about what happens after you quit your 9 to 5.” |
| A bold claim | “Walking is the most underrated workout there is.” |
| A question | “Would you take $1 million to never use your phone again?” |
| A number or list | “3 things I wish I knew before my first job.” |
| A warning | “Don't sign a lease until you watch this.” |
| A story already started | “So this happened at my cousin's wedding.” |
| The result first | “From 200 subscribers to 20,000 in a year. Here's how.” |
| A contrarian take | “Unpopular opinion: breakfast is overrated.” |
Every one of them makes a promise, and the clip has to keep it: a curiosity hook with no payoff gets people to the second second and loses them at the third. Templates for each kind, and which fit which videos, are in hook examples for short videos; the free hook generator fills 48 formulas with your topic.
Finding the hook in a clip of a long video
A clip of a podcast, stream or interview can't script its hook: it's somewhere in what was already said. The work is choosing where the clip starts.
- Start on the line itself, not the lead-in. Cut “so, yeah, I think the thing is…” and begin on the sentence that makes the claim.
- Start in the middle of the story, at the moment it gets interesting, and let the setup come out as it goes.
- Lead with the answer when the question is slow, then let the explanation follow.
- Add the hook on screen when the first words can't carry it: a line of text that says what's coming.
Questions
What is a hook in a video?
The first few seconds that make someone keep watching: the first line said, the first words on screen and the first frame. On short videos it has a second or two before viewers swipe.
How long should a hook be?
As short as it takes to make the promise: usually one sentence, said in the first two or three seconds, with a matching line of text on screen for people watching with the sound off.
What makes a good hook?
A clear promise the rest of the video keeps: a question viewers want answered, a claim they want to hear defended, a story already under way, or the result before the explanation. And no slow start before it.
What's the difference between a hook and a text hook?
A hook is everything in a video's first seconds that holds attention. A text hook is one part of it: the line of text shown on screen at the start, for viewers watching on mute.
What is a hook score?
A prediction an AI clipping tool makes for each clip, before you post, of how well its opening will hold viewers. Clyper's runs from 0 to 100, and is strict: 90 or more is rare.
