One prompt in, full music video out: Claude autonomously drives ComfyUI pipeline
Cheap_Credit_3957 · reddit · 2026-10-26
A Reddit user showed off a fully automated music video made by Claude (Sonnet 5.5) via their custom Video Builder MCP node for ComfyUI, prompted only with "create a theatrical rock/metal music video with creative costumes, female singer."
The model autonomously:
- Generated band and location reference images with a Krea2 text-to-image workflow
- Wrote the lyrics, composed the song with YUE2, built the full story, and wrote per-scene prompts
- Ran the builder overnight, then reviewed each scene frame-by-frame, fixing prompts and re-rendering failed scenes up to 3 times
The result needed no post-editing. The Video Builder is open-source on GitHub (comfyui-vrgamedevgirl), with a shareable 2-pass single-scene workflow JSON; the full builder is available via the author's Discord community.
