promptstring必需
Text prompt (3-2500 chars)
media_urlsstring[]可选
Reference media URLs. Supports images, videos (MP4/MOV) and audio (MP3/WAV); detected by file extension. Video and audio are billed per second by their length, which is measured when you submit.
image_urlsstring[]可选
Image-only reference URLs. media_urls takes precedence when both are provided.
input_imagestring可选
Deprecated. Alias for image_urls[0]
aspect_ratiostring可选默认 16:9
"1:1", "21:9", "4:3", "3:4", "16:9", or "9:16" (default: 16:9)

durationstring可选默认 4
"4" through "15" seconds (default: 4)
resolutionstring可选默认 720p
"720p" or "1080p" (default: 720p). These API values produce native 480p and 720p output respectively; billing is unchanged. Mini does not support 4k.

seedinteger可选
-1 to 4294967295. Fixes the generation seed for reproducibility. Supported by explicit "standard", "real", and "wild" modes, including real-mode asset:// inputs. When mode is omitted, the parameter is accepted but ignored. Set "mode" explicitly for reproducible results.

Seedance prompt guide

Seedance prompts work best as concrete director instructions. Describe the subject, action, scene, camera motion, visual style and constraints, then say what each reference file is for.

For image-to-video, the first image is the opening frame and an optional second image is the closing frame. For reference media, pass images, videos and audio in media_urls.
Describe each reference's role in the prompt in plain words ("the supplied cup", "the camera move from the supplied video"); do not refer to files by number or id.
For edits say "strictly edit the supplied source video"; to continue a clip say "continue from the supplied previous clip".
For complex scenes, list the shots in order, then a style and constraint package: stable faces, natural motion, no deformation, no watermark, no logo and no subtitles unless intended.

status

pending: Accepted and waiting to start. Keep polling.
processing: Running. Keep polling.
completed: Finished. Read video_url; output holds the full result.
failed: Ended without a result. error_message says why and credits_refunded shows what was returned.

Poll every 5 to 10 seconds and stop at completed or failed, or register a webhook to be notified instead. Failed tasks are refunded automatically.

Example pricing for text/image inputs. Resolution rows use the API values: 720p produces native 480p output and 1080p produces native 720p output. Standard and wild modes share the same rate; the real mode is billed slightly higher. Video or audio reference inputs incur additional per-second billing.
