  • ByteDance Doubao video generation model
  • Use model parameter to select doubao-seedance-1-0-pro-fast or doubao-seedance-1-0-pro-quality model
  • Supports text-to-video generation
  • Supports first frame / last frame / reference image control
  • Async task management, query results by task ID
Important Change: For better performance and cost control, we no longer support passing base64 image data directly in image_urls. Please use the Upload Image API first to upload images and get URLs, then call this endpoint.
