MiniMax H3 Digital Humans in ComfyUI: One Presenter, Two Characters, One Audio Lock

MiniMax H3 introduces new ComfyUI workflows focusing on digital humans and video upscaling. The digital human release features two graphs using the ref2va checkpoint and VoxCPM, enabling both single-character presentations and two-character dialogues with synchronized audio. Additionally, six upscaling graphs are provided, including five MiniMax H3 routes and one LTX 2.5 detailer to regenerate video detail while maintaining motion. These releases are based on saved graphs without specific claims regarding VRAM, timing, or quality.
