Henge is an open-source studio for motion transfer and character swaps on MiniMax H3
Henge is a free, open-source video studio that takes one guide video and a few pictures and gives the performance to a new character, swaps a character or only a head, or sharpens the footage. It runs MiniMax H3 through ComfyUI on your own GPU, on a rented RunPod machine, or from your PC with RunPod Serverless doing the rendering.
What it does
Each mode uses its own trained LoRA from the author's BFS collection (Character Swap v1.1, Motion Transfer v1.0, TARA v1.0, Head Swap v1.0 and Little More Sharpness v1.0), and the guide video's latents share the output's frame grid, so pose, camera and timing stay locked to the original. Long clips are split at camera cuts or at a fixed length and each shot can be previewed, redone and downloaded on its own. You can mark people with SAM 3.1 tracking and bind each one to its pictures, mask so the rest of the frame stays untouched, or add a new background that follows the original camera. A built-in assistant (Claude, OpenAI or a local model) or your own AI client over MCP can run the studio, and every job downloads as the exact ComfyUI graph it ran.
Worth knowing
Running it fully locally needs an NVIDIA card with 32 GB of VRAM and 64 GB of RAM (the README names an RTX 5090), plus about 125 GB of models; RunPod is the option without such a card. The demos in the README ran at 480p, with Sharpness taking results to 1080p. The app is MIT-licensed, while the Motion Transfer LoRAs use the BFS Motion Transfer licence. The author, Alisson Anjos, also made the TARA node already in this directory.
