Use this file to discover all available pages before exploring further.

Call /video/quote to get a price estimate, then poll /video/retrieve with the returned queue_id until complete. Private models also return a download_url for the finished video. It is a short-lived delivery URL (a few retries are fine if a download drops); see the Video Generation guide for details and optional DELETE for privacy.

​
Seedance 2.0

For seedance-2-0-* models (text-to-video, image-to-video, reference-to-video, plus the -fast-* variants), see the Seedance 2.0 Guide for the four-workflow model (Reference / Edit / Extend / Stitch), canonical prompt patterns, multimodal input limits, and pricing details.

​
Video upscaling

For the topaz-video-upscale model, use upscale_factor (1, 2, or 4) instead of resolution, and provide a video_url. Duration and FPS are detected automatically from the video file. See the Video Upscaling Guide for full details and examples.
