UNDERBOSS MEDIA · THE GROWTH VAULT · SWIPE FILE

The Short-Form Hook Library

A swipe-able bank of proven opening lines for consumer short-form video. The first one to two seconds decide whether your video gets watched or scrolled past. A strong hook opens a real gap in the viewer's mind or breaks the pattern they expected. A weak one warms up, explains, and dies before the point lands.

Use this like a swipe file. Pick a pattern, drop your product detail into the [fill-in] slot, and say it inside the first second. Every pattern below is copy-and-fill ready.

Rules of the Hook

A hook earns the next two seconds. It does not summarize the video, set context, or thank anyone. It creates tension and refuses to resolve it immediately.

What makes a hook work:

  • It opens a gap. The viewer needs to know what comes next and cannot guess it.
  • It is specific. Real numbers, real objects, real moments beat abstractions every time.
  • It has stakes. There is a cost, a payoff, or an identity on the line.
  • It hits in the first second. The strongest words go first, not after a wind-up.
  • It speaks to one person. A hook for everyone lands on no one.

What kills a hook:

  • Slow setup. "So I've been thinking about this for a while…" The clock already ran out.
  • Throat-clearing. "Hey guys, welcome back to my channel." Nobody opened a gap.
  • No stakes. If nothing is gained or lost, there is no reason to stay.
  • Abstraction. "Productivity is important." Vague claims give the eye nothing to hold.
  • Front-loaded context. Backstory belongs after the hook, never before it.

*Run this yourself: write five hooks for your next video using five different patterns, then pick the one that opens the widest gap. If you want this built on your actual product — your real users, your real moments, the openers that fit your category — the 20-minute diagnostic is open.*
