Hunyuan Video MultiGPU Setup

Hunyuan Video MultiGPU Setup is a Hunyuan Video workflow for generating video on multi-GPU systems. It uses text encoding and the listed checkpoint, VAE, and LoRA inputs, then samples, decodes, and combines video; device selection is optional.

Its named stages cover model, VAE, and text encoder loading; text encoding; LoRA selection and editing; sampling; decoding; and video combining.

The workflow lists these model files: hunyuan_video_FastVideo_720_fp8_e4m3fn.safetensors, hunyuan_video_vae_bf16.safetensors, and HYNV-Ellie-Lora01.safetensors.

HyVideoDecode and VHS_VideoCombine are its named video decoding and combining components.

To add the wrapper changes, replace two files in /custom_nodes/Comfyui-HunyuanVideoWrapper/ or download the ComfyUI-HunyuanVWMultiGPU repository.

Named node components include DownloadAndLoadHyVideoTextEncoder, HyVideoCudaSelect, HyVideoDecode, HyVideoLoraBlockEdit, HyVideoLoraSelect, and HyVideoModelLoader.

Other named node components are HyVideoSampler, HyVideoTextEncode, HyVideoVAELoader, and VHS_VideoCombine.

On a multi-GPU system, use HyVideoCudaSelect if you want to choose a device; device selection is optional.
