BWhat changed
Integrated dual-branch audio/video diffusion with cross-modal coupling, staged data curation and multidimensional post-training rewards to generate synchronized visual and audio sequences.
Scientific scope
Integrated dual-branch audio/video diffusion with cross-modal coupling, staged data curation and multidimensional post-training rewards to generate synchronized visual and audio sequences. Seedance video backbone, diffusion, RLHF and distillation are inherited. New jointly generated audio is the scoped system delta rather than a mere size/version bump. Lip synchronization and inference speed are source-reported; no audio/video was generated or evaluated here.

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
