Create a Seedance 2.5 video asynchronously. Use POST /v1/videos with a billing key: sd2.5-480p, sd2.5-720p, or sd2.5-1080p. On success you get a task_id. Poll Query video task and read result.video_url when the task completes.

Models

`model`	Notes	Duration	Resolution
`sd2.5-480p`	Billing key: 480p	5–30 seconds	`480p`
`sd2.5-720p`	Billing key: 720p	5–30 seconds	`720p`
`sd2.5-1080p`	Billing key: 1080p	5–30 seconds	`1080p`

Billing mode is per_second. Cost = the resolution unit price × requested seconds. Live prices come from the model catalog and the cost field on the response.

Modes

Mode	How to call
Text to video	Omit `images` / `videos` / `audios`, or send empty arrays
Reference generation	Pass reference images, videos, and/or audio

First and last frames are not supported.

Reference limits

Type	Max count
Images	9
Videos	3
Audio	1

Reference files must be publicly readable URLs.

Request fields

Field	Type	Required	Notes
`model`	string	yes	`sd2.5-480p` / `sd2.5-720p` / `sd2.5-1080p`
`prompt`	string	yes	1–5000 characters
`duration` / `seconds`	int \| string	no	5–30. Defaults to 5. Numeric strings such as `"10"` are accepted
`aspect_ratio` / `ratio`	string	no	`16:9`, `9:16`, `1:1`, `4:3`, `3:4`. Default `9:16`
`images` / `reference_images`	string[]	no	Up to 9 image URLs
`videos` / `reference_videos`	string[]	no	Up to 3 video URLs
`audios` / `reference_audios`	string[]	no	Up to 1 audio URL
`smart_queue`	bool	no	Default `false`. When `true`, a very low recent success rate keeps the task `queued` until recovery (up to about 2 hours). See Smart queue
