Time-Ad-7720 · reddit · 2026-10-23
A walkthrough of using MiniMax H3's Reference-to-Video workflow in ComfyUI for AI character swapping and motion transfer: replace the person in an existing video with a different AI-generated character and even change the environment, while keeping the original movements — no motion capture required.
Highlights:
- Runs locally on an RTX 5070 Ti
- Character references generated with Krea 2 and Qwen Image
- Prompt engineering and workflow tweaks for better consistency
- Tutorial page includes downloadable ComfyUI workflow, assets, step-by-step setup, and generation settings
The author sees this as a way to make character animation and indie filmmaking accessible without traditional animation or mocap pipelines.
