H3 Studio: open-source director-workflow for AI filmmaking on ComfyUI

Exciting-Income-5840 · reddit · 2026-10-17

A Reddit user open-sourced H3 STUDIOFILM, a ComfyUI-based "AI film studio" workflow. A simple prompt feeds a four-stage pipeline (content director → scene director → shot director → clip director), each stage editable manually or via natural language, with live visual references via Krea. A non-destructive Retouch mode supports deleting/replacing characters and elements, changing camera angles, swapping sets, and precise retakes. The author admits it's buggy and tricky to replicate across ComfyUI setups; repo: github.com/SpendinFR/H3STUDIOFILM.
