What this model accepts
Every value below is read from the same configuration the generator validates against, so this page cannot drift from what the API accepts. The upstream ID is a BytePlus public catalog name.
| Duration | 4–15s |
|---|---|
| Resolution | 480P / 720P / 1080P / 4K |
| Aspect ratios | 16:9 9:16 1:1 4:3 3:4 21:9 adaptive |
| Reference images | 9 |
| Reference videos | 3 |
| Reference audio | 3 |
| Reference video length | 2–15s per clip, 15s combined |
| Audio-only input | No |
| First / last frame | Up to 2 |
| Upstream model ID | dreamina-seedance-2-0-260128 |
| Credits / second | 11.4 |
Credits per second are quoted at 480P so they stay comparable with the table on Models. The generator shows the exact cost for your settings before anything is charged.
Need clips longer than 15 seconds, or audio-only references?
Seedance 2.5 runs 4–30s, accepts audio-only input, and quotes 16.6 credits/sec at its lowest resolution. It does not output 4K.

What this model is for
Seedance 2.0 is the cheaper, higher-resolution half of the pair. The numbers come from the same configuration the generator validates against.
The only model that outputs 4K
Resolutions run 480P / 720P / 1080P / 4K. Seedance 2.5 stops at 480P / 720P / 1080P, so anything that has to be delivered at 4K has to be generated here.
Lower per-second rate
At each model's lowest resolution the quote is 11.4 credits/sec here against 16.6 on Seedance 2.5 — roughly 31% less per second of output.
Where it gives ground
Clips cap at 15 seconds against 30, reference material caps at 9 images and 3 videos, and audio-only input is rejected. Those three are the reason to pay more for Seedance 2.5.
What this model rejects, and what to do instead
These are the rejections that actually happen in production, not a generic policy summary. Credits frozen for a rejected job are released automatically.
Photos of real people
Every Seedance model refuses to animate a recognizable real face, including your own and including images you hold the rights to. Switching models does not help — the check is upstream of both. The compliant path is to create a character under Assets from that image, then reference the character instead.
Reference video under 2 seconds
A motion reference shorter than 2 seconds is rejected on submission. This is about the reference clip's own length, not the length of the video you are generating.
Deleted or still-processing assets
A reference to an asset that was deleted after you selected it fails upstream, and retrying will never succeed. Reopen the character picker and select again — stale selections are dropped automatically when it reloads.
Prompts that trip content review
Prompt-level rejections name the prompt, not your reference material. Rewording usually clears it. Review on Seedance 2.5 is tighter than here, so a prompt rejected there may pass on this model unchanged.
