Seedance 2.0 Complete Tutorial: ByteDance AI Video Generation Breaks Through "Audio-Visual Sync" and "Physics Simulation"

Seedance 2.0

Seedance 2.0 is a multimodal AI video generation model launched by ByteDance's Seed Research Team on February 12, 2026.

In the past, using AI for video had three unresolved issues…

What architecture does ByteDance use for audio feature extraction in this model? I tried adjusting the frame rate to 60fps with WAV format, but physics simulation still occasionally clips through objects. I suspect the temporal length setting for motion prediction isn't sufficient.

I tried Seedance via the international version of Jimeng before; the audio-visual sync was better than I expected, but physics simulation still glitches a bit in high-speed motion scenes, possibly related to frame rate selection. Have you tested sync accuracy with different audio formats?
