Source description

Based on hunyuan video wrapper by kijai.

Update 1/1/25

This adds device selection nodes to hunyuan video wrapper.

I have included the workflow.

AND there is a download for the changed files if you want to just manually replace the 2 files in /custom_nodes/Comfyui-HunyuanVideoWrapper/

Or you can download the git from here.
