Watch: Seedance 2.0 generating native synchronized audio - no post-production required
Native Audio-Visual Synchronization
The End of the Silent AI Era
Seedance 2.0 is built on a Dual-Branch Diffusion Transformer that generates video and audio simultaneously via a shared Attention Bridge. Unlike every competing model that adds audio as a separate post-processing step, Seedance 2.0 grows the sound alongside the image. The result is frame-perfect synchronization: glass shattering at the exact millisecond it hits the floor, footsteps matching the surface material, and dialogue aligned with lip movements. This eliminates the entire post-production audio pipeline.
