# Frame 0 is the thumbnail

Story / Hook / Visual hooks and animations. Checked 2026-11-13.

The first frame already says what the video is about, in the feed and on the profile grid.

- Use when: Every video that will be judged by its cover.
- Phrase: the hook line in large type behind the speaker's head, readable on the very first frame

## Watch out

- Show only the first frame for two seconds and ask what it is about. No answer means the visual hook fails. (practitioner; Director Chair field notes on hooks and ideas)
- Eight of the nine measured reference edits start the first spoken word at 0.0 seconds. (measured; Director Chair measurements of published shorts (measured 22 and 23 Oct 2026))
