Build one clear social-video beat with Seedance
Pick the destination ratio before generation, keep the subject inside interface-safe space, and give a five-second clip one visual change. Add precise platform text later in your editor instead of asking the model to render it.

The short answer
A useful social clip is not a tiny film. It is one immediately readable change: a reveal, transformation, entrance, loop or reaction. Generate the motion cleanly, then add exact captions, logos and calls to action in an editor.
- Set 9:16 for Reels and Shorts or 1:1 for square feeds before the request.
- Describe the first visual state and the one change that should complete by the final second.
- Keep faces and products away from the top, bottom and right-side interface overlays.
- Ask for no text and no logo, then add both with deterministic tools after generation.
A five-second prompt with one readable beat
A cobalt-blue paper boat glides through a shallow stream as one warm shaft of sunlight crosses the frame. Low tracking camera, one continuous movement, clear subject in the center safe area, natural water ambience. No text, no logo, no cuts.
For vertical output, replace “center safe area” with the exact placement you need. Do not simply crop a landscape take if the subject will fall under UI controls.
Match the workflow to the destination
| Destination | Ratio | Seedance brief | Finish later |
|---|---|---|---|
| Reels / Shorts | 9:16 | One centered subject and vertical movement | Captions, hook text, CTA |
| Feed post | 1:1 | Balanced central composition | Logo and copy |
| YouTube / site | 16:9 | Wider environment and camera path | Title card and end card |

Frequently asked questions
Should I ask Seedance to add captions?
No for publish-ready text. Ask for no text, then add exact captions in an editor so spelling, timing and accessibility remain under your control.
How long should the first test be?
Five seconds is enough to test the hook, composition and motion at lower cost. Extend only after that beat works.
Can I reuse one clip everywhere?
You can, but a dedicated ratio usually performs better than automatic cropping because platform interfaces cover different parts of the frame.
The example is a first-party paid provider output. Platform specifications and interface safe areas can change; check the destination before publishing.
