VideoGrain: Modulating Space-Time Attention for Multi-Grained Video Editing

什么是VideoGrain: Modulating Space-Time Attention for Multi-Grained Video Editing

VideoGrain is an advanced method designed to enhance video editing by providing fine-grained control over video content. It addresses challenges like semantic misalignment and feature coupling within the diffusion model by using space-time attention mechanisms. This zero-shot approach allows for class-level, instance-level, and part-level video editing with impressive precision.

VideoGrain: Modulating Space-Time Attention for Multi-Grained Video Editing怎么用？

Using VideoGrain involves modulating both cross-attention and self-attention within the diffusion model. In the cross-attention phase, local prompts are paired with their respective regions to improve text-to-region control. For self-attention, VideoGrain amplifies the attention within a region and reduces cross-region interference, allowing for greater feature separation and control over the video output.
