Asset and Scene Limits

Seedance 2.5 Lite reference-material mode is a special-price full-capability route with a built-in asset library, no facial distortion, a 100% pass rate for real-person content, and long-term stability. It bills at special-offer rates and only successful tasks are charged — see the pricing page for live rates.
  • Text prompt: For Chinese, keep it under 500 characters; for English, under 1,000 words.
  • Image input: Supports jpeg, png, webp, bmp, tiff, gif, heic, and heif formats; each image under 30 MB; aspect ratio range (0.4, 2.5); width and height range (300px, 6000px).
  • Image count: No more than 30 images.
  • Video input: Each video 2–30 seconds; up to 10 reference videos; total video duration must not exceed 30 seconds.
  • Audio input: Each clip 2–30 seconds; up to 10 reference audio clips; total audio duration must not exceed 30 seconds.
  • Audio input restriction: Audio cannot be provided on its own; at least one reference image or reference video is required.
  • Resolution: 720p only — 480p, 1080p, 2K and 4K are not supported on this route.
