Vidu Motion Sync
[Core Function] Vidu Motion Sync is a video-to-video motion transfer model. [Strengths] It excels at accurately extracting physical motion from a source video (e.g., a dancing person) and applying it to a target character image, preserving the target’s identity. [Best For] Highly recommended for: creating dance videos with custom characters, transferring complex choreography, and replicating specific physical actions onto avatars. [Limitations] Do NOT use this model if you want to change what a character is saying (use Lip Sync). It requires both a reference video for motion and a target image for appearance. [Routing] Use this model specifically when the user wants to copy the body movements or actions from one video onto a different character.
