- Uses hierarchical architecture to solve motion drift in long sequences

## The update

Alibaba Tongyi Wanxiang has officially open-sourced Wan-Dancer, a music-driven model for generating portrait dance videos. By simply providing a portrait photo and a music track, users can create dance videos with precise beat synchronization and natural, fluid body movements. This technology breaks through the performance bottlenecks traditional models face when generating long-sequence videos, capable of stably producing coherent 720p HD footage ranging from 15 seconds to 3 minutes in duration, covering various dance styles. Technically, Wan-Dancer employs a hierarchical architecture that combines global keyframe planning with local temporal refinement. This structure effectively addresses the common issue of motion drift in long-sequence video generation, ensuring action consistency and visual stability for characters throughout extended dance routines, thereby providing creators with a high-quality video generation tool.
