LongCat Video Avatar: Audio-Driven Long-Form Generation
LongCat Video Avatar is the audio-driven lane of the LongCat stack: one portrait plus one audio track becomes a talking-head clip with synced lip motion. It runs locally β the LongCat video avatar guide documents the Avatar-1.5 checkpoint and the commands, and our hosted browser tool is image-to-video only: it takes a still image and a motion prompt, and it has no audio input.
