Hook
A hook is the opening of a short video — usually the first one to three seconds — that makes a scrolling viewer decide to keep watching. It has a visual part (the first frame: a face mid-sentence, a result, something in motion) and a verbal or text part (the first line spoken or shown on screen). Common hook types: a bold claim, a specific question, a visible result shown before the explanation, a mistake or warning, or a story dropped in at the most tense moment. A good hook makes a promise the rest of the clip keeps. A clickbait hook that the clip does not pay off may win the first second and lose the rest, which shows up as a cliff in audience retention.
In a HypeNest pass
HypeNest looks for self-contained moments in a long recording and starts each clip candidate as close to the point as possible. During review, check the first two seconds with sound off: is it clear who this is for and what they will get? If the clip opens on a greeting or a setup question, trim to the line that carries the idea.
FAQ
- How long is a hook on YouTube Shorts or TikTok?
- Treat the first one to three seconds as the gate. There is no official length; the retention curve shows where viewers actually leave.
- Should the hook be spoken or on-screen text?
- Both, ideally. Many people scroll muted, so a short text line that matches the spoken opening covers both cases — placed inside the safe zone.
- Can AI write the hook?
- It can propose lines. You still pick the one that matches the visual and the clip’s real payoff. That is what review before publish is for.
