A developer shares a 6:16 Ultima Online fan short film built entirely with open-weights MiniMax H3 in ComfyUI on a single RTX PRO 4000 Blackwell (24GB): 72 shots at 1344x768@24fps, 1,200 takes reviewed over two weeks. Pipeline: character/set reference cards via Gemini (Nano Banana, the only closed tool), fixes with local Qwen-Image-Edit, H3 reference-to-video for main shots, timbre-cloned voices cut from earlier takes, first+last-frame i2v for bridge shots, draft-then-HD rendering, and game assets extracted with UOFiddler. Claude helped write prompts and QC/edit scripts.
