Key Parameters and Limits

Seedance 2.5 Lite Text to Video shares the full 2.5 contract with the discount routes — 4–30 second clips with native audio-video joint generation — and differs only in billing tier and resolution: special-offer billing, 720p-only output.
  • Text prompt: For Chinese, keep it under 500 characters; for English, under 1,000 words.
  • Duration: 4–30 seconds per clip (default 4s).
  • Resolution: 720p only — 480p, 1080p, 2K and 4K are not supported on this route.
  • Aspect ratio: adaptive (default), 16:9, 9:16, 1:1, 4:3, 3:4, 21:9.
  • Native audio: generated with the picture and on by default (generate_audio=true); disable per request if not needed.
Special-offer billing applies and only successful tasks are charged — see the pricing page for live rates. This is a full-capability route: media URLs are submitted to the asset review service before the task is submitted by default (real_person=true); set real_person=false only when the materials are confirmed face-free to pass media URLs through as-is, so plain public URLs always work in requests.
