ComfyUI-VDN-H3

Ports VDN into ComfyUI for MiniMax-H3, patching attention at runtime - exact softmax for nearby frames, a constant-cost recurrent linear branch for distant temporal context - without touching ComfyUI core. Needs the H3 base weights plus a Qwen3VL-32B text encoder and separate video and audio VAEs. On a single RTX 5090 at int8, 1280x736 and 145 frames it runs about 17 seconds an iteration, roughly two and a quarter minutes total; the paper's headline 74.5x needs eight GPUs and kernels consumer hardware does not have. The node is Apache-2.0, the weights gated under the MiniMax H3 community licence.
