Specifications
Seedance 1.5 Pro is ByteDance's first Seedance model to generate sound and picture together. On SeedVideo AI it makes 4 to 12 second clips from a text prompt, a first frame, or a first and last frame, with voices, effects and music in the same pass, at 480p, 720p or 1080p. It has the lowest list price of any video model on the site: 0.6 credits per second at 480p, 1.2 at 720p and 2.6 at 1080p, about $0.03 to $0.18 per second at 480p and 720p depending on plan. The free plan runs it at up to 720p. Pick Seedance 2.0 Mini for 15-second clips and reference images, or Seedance 2.5 for 30 seconds.
