Model-specific parameters

Parameter	Type	Default	Description
`seedanceParams.duration`	integer	`8`	Video duration in seconds, any integer from `4` to `15`
`seedanceParams.resolution`	string	`"720p"`	Output resolution: `"480p"` or `"720p"`
`seedanceParams.aspect_ratio`	string	`"16:9"`	Aspect ratio: `"21:9"`, `"16:9"`, `"4:3"`, `"1:1"`, `"3:4"`, `"9:16"`, or `"adaptive"`
`seedanceParams.start_image`	string	—	URL or `asset://{assetId}` for the first frame
`seedanceParams.end_image`	string	—	URL or `asset://{assetId}` for the last frame
`seedanceParams.reference_image_urls`	string[]	—	Up to 9 reference image URLs or asset URIs
`seedanceParams.reference_video_urls`	string[]	—	Up to 3 reference video URLs or asset URIs
`seedanceParams.reference_audio_urls`	string[]	—	Up to 3 reference audio URLs or asset URIs
`seedanceParams.generate_audio`	boolean	`true`	Enables synchronized audio generation. Audio is included in the base price.
`seedanceParams.return_last_frame`	boolean	`false`	Returns the last frame of the generated video
`seedanceParams.web_search`	boolean	`false`	Enables web search grounding for the prompt
`seedanceParams.seed`	integer	—	Optional random seed for reproducible generations
`seedanceParams.camera_fixed`	boolean	`false`	Locks the camera for more static motion

Asset references

Reference fields (start_image, end_image, reference_image_urls, reference_video_urls, reference_audio_urls) accept both direct URLs and asset URIs in the format asset://{assetId}. Use the Assets API to pre-upload media and obtain asset IDs.

Credit cost

Pricing is per second of output. The total credit cost is credits-per-second × duration. Reference images and audio do not affect cost; only reference_video_urls does (it shifts pricing to the *-refvid rate because reference video changes the upstream generation mode).

Variant	Credits / sec
`480p`	7
`720p`	16
`480p-refvid`	9
`720p-refvid`	19

Examples: a 5-second 720p clip costs 16 × 5 = 80 credits; a 15-second 720p-refvid clip costs 19 × 15 = 285 credits.
