For five weeks we would not say how our presenter’s talking footage is made. Here is the whole chain: LongCat for the body, MuseTalk for the mouth, Duix to clean up what that leaves, and MuseTalk again for the visemes. Why the order matters more than any single model.
Duix (formerly HeyGem) is the open-source HeyGen clone, it clones a face from a short video and re-lip-syncs it to any audio, offline on an NVIDIA card. We installed it and ran it. Here’s the honest result.
LongCat animates a whole body, gestures, lean, face, mouth, from audio, locally, for free. Long takes in one job. It’s our pick for a full-body local host, with two honest caveats: a quiet background, and drift on very long takes.
