Cheap_Credit_3957 · reddit · 2026-10-20
A Redditor shared a full band-performance AI video built with MiniMax H3, with almost no manual post-editing, along with the complete workflow and their open-source ComfyUI video builder (GitHub, MCP/API support).
Key pipeline details:
- Song by Suno, lyrics by ChatGPT; a custom GPT plugin auto-generates band, song style, and locations
- Video: MiniMax H3 Singularity at 25 steps on pass 1, then the 8-step 768p turbo LoRA at 4 steps with 0.35 denoise plus a latent upscale model on pass 2
- Automation: Claude via MCP/API planned all scenes, wrote every H3 prompt shot-by-shot with lyric cues and emotion tags, rendered overnight, checked takes frame-by-frame and re-shot problems, and verified cuts and audio sync (0 ms drift)
- The two-pass workflow file is included in the repo, and a Claude-free story mode is in development
A directly reproducible "LLM agent as director + video model renderer" pipeline for automated short-form video production.
