The authors analyzed bidirectional cross-attention in joint video-motion and video-audio diffusion transformers.
Reciprocal attention regularization improves alignment in joint video generation
RecCAR strengthens how motion and audio constrain generated video by aligning the model’s weaker cross-modal attention pathway with its stronger reciprocal pathway.
