ComfyUI Workflows Boost MiniMax H3 Video Generation by 12x
lumos_ai · reddit · 2026-08-04
A developer created 3 free ComfyUI workflows to accelerate MiniMax H3 video generation by 12x using a 'low-res generation + upscale' strategy, achieving near-native 1080p quality.
Technical Details:
- Upscalers: Supports one-click switching between LTX 2.3 and Wan 2.2 5B for upscaling.
- Sigma Fix: The author notes that popular workflows have sigma values set too high, causing distorted faces and broken lip sync. These workflows are tuned to stay true to the source.
