# Writing a Hook for Short-Form Video Ads

> Learn how to write hooks that stop the scroll in the first 2-3 seconds, then produce multiple variations fast using Captions AI Ads.

The first 2-3 seconds of your video determine whether someone keeps watching or scrolls away. A strong hook is the single highest-leverage thing you can improve in a short-form ad, and testing multiple hooks is the fastest way to find what works for your audience.

## What makes a hook work

Every effective hook does at least one of these things:

* **Pattern interrupt:** say or show something the viewer wasn't expecting
* **Address a pain directly:** "If you're struggling with X, keep watching"
* **Make a bold claim:** "I doubled my revenue with this one change"
* **Ask a question:** "Are you making this mistake?"
* **Visual contrast:** open with a before/after or unexpected image in the first frame

The audio hook and the visual hook work together. What's on screen in the first frame matters as much as what you say.

## The four hook types

**1. Problem hook:** state a problem your viewer is already experiencing. They recognize themselves and keep watching to find the solution.

**2. Curiosity hook:** tease information they want but don't give it away. "The reason most people fail at X has nothing to do with X."

**3. Contrarian hook:** challenge a belief your audience holds. "Stop doing X. Here's what actually works."

**4. Result hook:** lead with the outcome. Show or state the result first, then explain how.

Write at least 3-5 hook versions before you start producing. Each hook type reaches a different segment of your audience.

## Producing hook variations in Captions

<Steps>
  <Step title="Write your hook variations">
    Write 3-5 different hooks for your script before opening Captions. Keep each hook under 3 seconds when spoken aloud. Avoid starting with "Hey guys," your name, or your brand name. Get to the hook immediately.
    <Tip>Test your hook by reading it out loud with a timer. If it takes longer than 3 seconds, cut it down.</Tip>
  </Step>

  <Step title="Open AI Ads">
    From the Captions home screen, tap **AI Ads**. You can paste a product URL to auto-generate ad content, or write your own script with one of your hook variations at the top.
  </Step>

  <Step title="Generate your first ad">
    Paste or type your script, starting with your first hook, and generate the ad. Review the output before moving to the next variation.
  </Step>

  <Step title="Create variations for each hook">
    Use the **Ad Variations** feature to generate multiple versions quickly. Swap in each hook version as the opening line of your script and generate a new variation. Each variation becomes a separate project in your library.
    <Tip>Keep everything after the hook identical across variations so you're testing only the hook, not other variables.</Tip>
  </Step>

  <Step title="Export and test">
    Export each variation and post them on the same day or in the same campaign. Compare watch time and retention in your platform analytics. The hook with the highest average watch percentage is your winner.
  </Step>
</Steps>

## Tips

* Hooks under 3 seconds perform best on TikTok and Instagram Reels
* Don't start with your brand name, "Hey guys," or any greeting. Every word counts
* The visual hook (what's on screen at frame one) matters as much as the audio
* Contrarian and problem hooks tend to outperform result hooks in cold audiences
* Once you find a winning hook, write 3 variations of that hook type for your next batch
