Gradio UI for training video models using finetrainers

ComfyUI-HunyuanVideo-Avatar is now available in ComfyUI, HunyuanVideo-Avatar is a multimodal diffusion transformer (MM-DiT)-based model capable of simultaneously generating dynamic, emotion-controllable, and multi-character dialogue videos.

ComfyUI-HunyuanPortrait is now available in ComfyUI, HunyuanPortrait is a diffusion-based condition control method that employs implicit representations for highly controllable and lifelike portrait animation.

Custom tool set mostly for Hunyuan Video, but includes some WAN Video nodes.
