Deliverable: beat sheet (Chinese OK) + segmented H3 prompts. No compositing work.
Pre-writing information
- Material facts that can go into the visuals: LOGO/product/interface/claim/CTA (do not imitate without authorization; mark as concept)
- Duration (usually 15–30s), aspect ratio, audience, copy language (follow the brand and platform, not the chat language mechanically)
Narrative spine (write into each segment's style sentence)
| Type | Spine |
|---|---|
| SaaS/AI | Intent→planning→capability→execution→output→proof→LOGO |
| Entity | Hero→interaction→close-up→scene→result→LOGO |
| Service | Background→process→evidence→outcome→promise→LOGO |
15s≈5–8 beats; 30s≈8–12 beats.One primary action per beat.
Beat draft
| Time | Visual lead | Action | Proof point | Copy | Intent (setup/impact/brake) |
|---|
Transitions preferred: product action, interface flow, edge match; avoid fake HUDs and unverified metric walls.

15s: multi-segment prompt + linking sentences; hard cuts land at action completion or copy line changes.
