ComfyUI Plugin Fixes MiniMax H3 Fast Motion Artifacts
MatlowAI · reddit · 2026-08-09
MiniMax H3 struggles with bursty motion artifacts because a single latent token spans 4 frames and cannot hold distinct poses.
A new ComfyUI-MAINodes plugin tackles this by:
- Detecting high-acceleration areas in the clip's latent space
- Retiming with held frames and regenerating via partial video-to-video denoising
- Dropping held frames for real-time recovery, with audio jointly regenerated and retimed
The author also shared workflows testing LightX2V 4-step turbo acceleration, noting that while base + turbo is good for drafting, turbo LoRAs aren't worth the time savings for final renders.
