Building a fully local AI video factory with ComfyUI and MiniMax H3

A developer with a 100+ GB VRAM workstation posted seeking advice on building a fully local, automated YouTube video generation pipeline using the MiniMax H3 model within ComfyUI.
The envisioned workflow requires only two inputs: a master prompt describing the channel's niche and style, and a prompt for the specific video. The system would automatically handle script generation, consistent character design, reference image and voice generation, scene editing, and final rendering—acting as an infinite content factory. The developer previously found LTX 2.3 mediocre for this task, but believes MiniMax H3 makes the concept viable. They are looking to collaborate with others interested in over-engineered ComfyUI workflows.
