InfiniteTalk Video-to-Video (motion + lip-sync)

Audio-driven lip-sync applied on top of a driving motion clip. Loads a source video (e.g. a subject dancing/twirling from a t2v/i2v run), encodes its motion, and re-samples it to lip-sync a voice line while preserving the body motion (Wan 2.1 I2V backbone + InfiniteTalk/MultiTalk). Use this instead of infinitetalk_i2v when you want real body motion, not just a talking head.
