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

Seedance 2.0 is the standard tier of ByteDance's Seedance family. Duration is any integer 4-15 seconds, currently 720P, six aspect ratios, with an optional generated soundtrack; omit the reference image for text-to-video, include one (first frame by default) for image-to-video. 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

Standard short-form production

4-15 seconds covers most social and ad asset lengths.

Image-to-video

Animate a still while keeping the subject consistent, using the reference as the first frame.

Multi-ratio delivery

Run the same prompt at 16:9 / 9:16 / 1:1 to reuse one idea across platforms.

Clips with sound

audio is on by default, so clips ship with ambient sound and skip a separate audio pass.

How to choose

2.0 and 2.0 Fast have identical envelopes (duration, resolution, ratios and reference limits all match) — they differ only in speed and price, and Fast wins on both. Unless you specifically want the standard tier's look, use seedance-2.0-fast. For more than 15 seconds, use seedance-2.5.

FAQ

Why 720P only?

The upstream currently serves 2.0 at 720P only; any other resolution returns a clear 400 rather than silently downgrading. We will follow as soon as more tiers open.

How is it different from 2.0 Fast?

Same envelope; Fast renders quicker and costs less. In our testing Fast held up just as well on motion, so prefer it when cost matters.

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.
