Seedance 2.5 4K is billed per video token, exactly as Seedance 2.5 is, at the 4K tier. Tokens = output width x height x frame rate x duration / 1024, so a 4K second is about 4x a 1080p second.
With a reference video, the whole request is billed at the lower video-input rate, and every reference video is billed for its full length on top of the output, counted at the output's 4K resolution (whatever the clip's own resolution).

How the charge works
- On request: a temporary hold is placed on your credits.
- On completion: you are charged for the tokens the render used; the rest of the hold is released.
- Failed or moderated renders are not charged.
Tips
- Render drafts on seedance-2.5 at 480p and use 4K only for the final shot.
- 4K renders take several minutes: use the async API (POST /v2/seedance-2.5-4k) and poll.
