MiniMax Director — a ComfyUI timeline editor that covers every documented H3 feature
I built a ComfyUI workflow that gives H3 a timeline instead of one prompt box, and I tried to cover every documented feature of the model.
Tracks for picture, camera and audio. Take a person, a prop, a place, a style or a voice out of any file — each becomes a card you paste into any segment, and it stays the same across shots. It compiles the six-section reference format, task types, dialogue in the model's exact <d> form, frame anchors and on-screen text, and it enforces H3's own rules before you run: 24 fps, clip length 5 + 17n frames, 9 images / 3 videos / 3 audio / 12 files. A report node lints the graph; a prompt node shows the exact text the model receives.
