Reference image role

Reference image URLs (optional, one per line, up to 4)

With multiple references, address them in the prompt as @Image1 / @Image2, e.g. "the character from @Image1 stands in the scene from @Image2". Without tokens the model decides on its own.

Reference audio URLs (optional, one per line, requires a reference image; up to 1)

Reference video URLs (optional, one per line, cannot combine with a reference image; public http(s) only; up to 3)

Rendering takes 2-12 min (longer clips take longer); billed per second, fully refunded on failure. Prompt limit 5000 bytes (about 1666 Chinese characters).

About Seedance 2.0 Fast

Seedance 2.0 Fast is the low-latency tier of the Seedance family, and the fastest and cheapest video model on the station. Its envelope matches 2.0 exactly: any integer 4-15 seconds, 720P, six aspect ratios, optional generated soundtrack. Async job: POST /v1/videos/generations returns HTTP 202 and a job id immediately; poll GET /v1/videos/jobs/{id} until status=succeeded and read data[0].url. That link is an mp4 re-hosted by us — it will not expire the way the upstream CDN link does.

Use cases

Bulk asset production

Fastest and cheapest — generate a batch of candidates and pick by hand.

Fast creative validation

Prove the shot list and camera moves here before spending on a pricier model.

Image-to-video

With the reference as the first frame, subject and scene detail carry through reliably.

Clips with sound

audio is on by default, so clips ship with ambient sound.

How to choose

Start here by default. You only need to move when you want more than 15 seconds (seedance-2.5) or 1440P with native audio (minimax-h3).

FAQ

Does "Fast" mean lower quality?

It is the low-latency tier of the same generation as 2.0, with an identical envelope. On a demanding action prompt it produced mid-air leaps, a rolling camera and a snow-burst impact — holding its own against pricier tiers.

Why 720P only?

The upstream currently serves the 2.0 line at 720P only; anything else returns a clear 400 rather than silently downgrading.

How does image-to-video work?

Pass an image (public URL, data: URI or base64). By default it becomes the first frame, so the clip keeps the reference subject and framing. A second image becomes the last frame; set image_role=reference to switch to subject/style reference mode instead. The first/last-frame and reference modes are mutually exclusive.

How is it billed, and am I charged on failure?

Billed per second: the hold placed at submit is computed from the duration you asked for, and the settle is the exact same number. A failed or timed-out render refunds the whole hold, so you never pay for a clip you did not receive.
