Why Choose Seedance
General-Purpose Video Model
Seedance is ByteDance's all-round AI video model: people, products, landscapes or animation — with fluid motion and dance among its strongest suits.
Up to 30 Seconds in One Take
Seedance 2.5 renders a single continuous shot of 4-15, 20 or 30 seconds. Seedance 2.0 covers 4-15 seconds per generation.
Native Synchronized Audio
Both generations create sound together with the picture. On Seedance 2.5, a line wrapped in straight double quotes is spoken with matching lip movement.
Two Generations, One Editor
Pick Seedance 2.5 at 480p or 720p, or Seedance 2.0 when you need 1080p. Both accept up to 9 reference images and work from text, an image, a video or a template.
What You Can Create with Seedance
Dialogue Scenes
Put a spoken line in straight double quotes in a Seedance 2.5 prompt and the character delivers it with lip-synced audio — perfect for talking-head clips and short skits.

Up to 30 seconds in one continuous Seedance 2.5 take — enough for a complete scene with a beginning, a turn and an ending, without stitching clips.
