Input

videoContent requirements
- Everything is reviewed
The prompt, the reference files and the finished clip all go through content review, picture and sound alike.
- No charge if rejected
A rejected job is not charged; the credits held at submit are refunded in full.
- The finished clip is reviewed again
Some jobs are rejected at submit; others only when the finished clip is reviewed, anywhere from a few minutes to over half an hour later.
- Sound is reviewed too
Spoken lines, narration and lyrics in your prompt are voiced or sung, and reviewed together with the picture. If you need no voices, leave out lines and lyrics. This model always adds a soundtrack; it cannot be turned off. Uploaded reference audio is reviewed as well.
- Commonly rejected
Sexual content or nudity; gore, self-harm and violent injury such as gunshot wounds; firearms, explosives and drugs; minors shown with alcohol, tobacco or in danger; politicians, celebrities and other public figures, in looks or voice (look-alikes included); copyrighted characters.
- One bad shot fails the whole clip
If a single shot in a long storyboard script breaks the rules, the whole clip is rejected. Resubmitting the same input is rejected again; fix that part or replace the reference, then retry.
About Seedance 2.0 Fast
Seedance 2.0 Fast is the low-latency tier of the Seedance family, built for quick turnaround. It is the low-latency tier of Seedance 2.0: any integer 5-15 seconds, 480P / 720P, five aspect ratios (16:9 / 9:16 / 1:1 / 4:3 / 3:4), optional generated soundtrack (1080P lives on seedance-2.0). 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 is kept for 7 days (far longer than the upstream CDN link), so download it or copy it to your own storage before then.
Use cases
Quick turnaround — generate a batch of candidates and pick by hand.
Prove the shot list and camera moves here before spending on a pricier model.
Reference images pin down the subject, wardrobe and scene, so product shots and character sheets come alive; name them @Image1 / @Image2 in the prompt and the identity carries through.
audio is on by default, so clips ship with ambient sound.
How to choose
Start here when budget or volume comes first. Move to seedance-2.0 for more visual headroom or 1080P, to seedance-2.5 for more than 15 seconds, or to minimax-h3 for 1080P with native audio.
