First three seconds self-test
Review the opening you already have. Ten concise questions assess first-frame clarity, cold-viewer context, momentum, caption timing, and payoff readiness. The tool runs entirely in your browser, requires no login or email, and does not upload your video or call an AI service.
This checklist does not predict views, retention, reach, or virality. It turns your own observations into prioritized edit checks.
How to run the test
Open the cut you are about to publish and scrub to the first frame. Answer each question against what is actually on screen, not what you intended to put there. The most useful answers come from watching the opening twice: once with sound, once muted.
Muting matters because you already know what the video is about. Removing the audio removes some of the context you carry as its maker, which is the closest you can get to a cold viewer without showing it to one.
What the five dimensions mean
- First-frame clarity
- Whether the opening image places the subject, the tension, or the result without the viewer having to guess.
- Cold-viewer context
- Whether someone who has never seen your account can follow what is happening in the first second.
- Momentum
- Whether the opening moves toward something, rather than spending attention on activity that reveals nothing.
- Caption timing
- Whether on-screen text arrives with the moment it explains, or one beat after the confusion it was meant to prevent.
- Payoff readiness
- Whether the viewer can tell, roughly, what they are staying for, and how far away it sits.
The ten questions
What this test cannot tell you
The score is a sum of your own answers, weighted consistently. It has no access to your account, your platform analytics, or any recommendation system, and it cannot know how real viewers will respond. Two videos with identical scores can perform very differently, because distribution, topic, timing, and audience all sit outside the edit.
What it can do is make an opening’s structural weak points explicit while the timeline is still editable. For a fuller pass across the whole cut, read how to check your hook before posting, or see how the hook review works.
