About

ByteDance's Seedance 2.0 generates high-quality video from text prompts and multimodal references, with fixed 24 fps output and durations up to 15 seconds.

Full Seedance 2.0 supports T2V, I2V, image+audio-to-video, and V2V workflows, including 1080p and native 4K paths. Mini is the faster, lower-cost 720p tier for iteration. It replaces Seedance 2.0 Fast; legacy Fast model IDs are automatically routed to Mini.
