Minimax H3 Face Detailer Workflow Fixes Distant Face Distortion
listopalafoto · reddit · 2026-08-13
The MiniMax H3 video model often struggles with facial details when the character's head occupies a small fraction of the frame. Traditional upscalers cannot fix this as they only sharpen existing artifacts rather than synthesizing missing facial structures.
To address this, a developer has open-sourced a ComfyUI face detailer workflow. The core methodology includes:
- Cropping the face area from the original frame to fill the canvas
- Regenerating the face using H3 at a low denoise strength to maintain frame alignment
- Compositing the refined face back into the original video
This workflow provides a practical solution for video creators to overcome the model's native limitations in rendering distant faces.
