Seedance 2.0 Video Generation

Seedance 2.0 supports text-to-video, image-to-video, first-last-frame generation, multi-reference generation, and compatible edit or extension modes. New integrations should use the new create task page, not the deprecated old task interface.

Billing Notes

Seedance billing depends on the selected model tier, output resolution, duration, and whether reference media or audio generation is used. Final billing should follow the platform settlement record.

Sending more than 9 reference images.
Sending more than 3 reference videos or reference videos whose total duration exceeds 15 seconds.
