A TikTok caption sits on the screen while the video is already playing, competing with the footage for the same half second of attention. It’s not describing what’s happening, the viewer can already see that. It works better as a hook: a reason to keep watching, a question, a setup line the video then pays off.
That’s the difference from a caption on a still photo. Short works, but short and pointed works better. If the caption just restates the video, it’s wasted space.

How to pick one
Pick the hook that matches the first three seconds of footage, not the whole video. If your opening shot is confusing on its own, the caption should clarify just enough to keep someone watching, not explain the entire clip. Questions and unfinished thoughts (“wait for it,” “you won’t guess”) work because they create a reason to stay, so lean on those over flat descriptions. Keep it short enough that it doesn’t cover the action on screen, and check the exact length with a TikTok character counter if you’re running long. When you’re blanking on a hook entirely, an AI TikTok post generator is a fast way to get a handful of options to react to.
