MiniMaxDirector: a timeline for H3
I wrote a ComfyUI node for MiniMax H3 and released it as open source: MiniMaxDirector. Instead of packing an entire film into one prompt box, you lay it out on a timeline — what happens on screen, how the camera moves, what is heard — and it compiles that into the single structured prompt H3 actually reads.
What it does for you:
- Three tracks. Shots, camera and audio, each segment with its own text and its own span.
- Cut times are computed, so the model is told exactly when each shot begins.
- Legal lengths only. The clip is snapped to a duration H3 accepts, so a run cannot fail on arithmetic.
- Attach a file to a segment and it becomes a numbered reference in the prompt automatically — no tokens to type by hand.
It is already installed on your GPU. Start the MiniMax H3 bundle and open Docs → Media → MiniMax H3 → the MiniMaxDirector workflow; the graph is ready to run, nothing to install.
On your own machine, it is on the ComfyUI registry as minimax-director — searchable in the ComfyUI Manager, or comfy node install minimax-director. Source and issues: github.com/imbutus/ComfyUI-MiniMaxDirector. MIT licensed.
