## Prompt tips

- Prompt cap is 1800 chars; be specific about subject, action, style, and setting. No native audio — plan sound as a separate pass.
- Durations 5 or 10s with a hard trade-off: 10s cannot be 1080p, 1080p cannot exceed 5s — pick per deliverable.
- Text runs REQUIRE an aspect ratio (16:9/4:3/1:1/3:4/9:16); image runs IGNORE it — the input image dictates output dimensions.
- Image-to-video treats the image as the anchor frame: describe motion and camera, not the still.
