Hook for a generated video: what must be in frame 1 when a model draws it

Write the hook shot for a generated short video about {topic}, as a standalone 4-second generation prompt. The viewer decides on frame 1 (about 0.1 to 0.5 s for younger audiences, 1 to 2 s for older ones, per the creator-growth skill), so the hook shot is generated separately, judged at thumbnail size, and only then is the rest of the video made.

Frame 1 rules for a model:
- The subject is already in frame at full size and already mid-action: 'a hand already lifting the lid', not 'a hand reaches for the lid'. Models ramp motion from a still; write the action as in progress.
- One strong motion that reads at thumbnail size: steam, pouring, a door opening, a page turning, a cursor moving. Name it; do not ask for 'dynamic'.
- Close-up or medium close-up. Wide shots have nothing to look at in 0.5 s.
- Light from one named side so there is a bright and a dark half; flat light reads as a render.
- No on-screen text, no logos, no subtitles in the generation; the hook text is added in the editor in the platform font, so it stays sharp and editable.
- 4 seconds, 9:16, the camera static or a slow push in. No orbit, no whip pan on the hook shot.

Write the hook shot in this shape: subject already {mid-action}, {setting}, {medium close-up / close-up}, {static / slow push in}, {light from one side}, {style}, {ambient sound}, 4 seconds, 9:16, no on-screen text, no logos.

Then: the hook TEXT line to add in the editor (max 7 words, upper third), and a 2-line note on what to check at thumbnail size before generating the other shots (is the motion visible, is the subject identifiable, does the bright half hold the subject).

Topic: {topic}
What the first second must show: {the subject and the motion}
