Using Minimax H3 as an image-edit model: settings and banding tips?
ItwasCompromised · reddit · 2026-09-22
The author saw comments about using Minimax H3 as an image model but cannot find any workflows or settings, so they ask for help.
Specific questions:
- An image VAE is needed, but ComfyUI nodes require a duration of at least 0.1 — how do you output exactly one frame?
- Should shift values be changed? Which sampler/scheduler is needed? How many steps?
- Is it worth combining turbo LoRAs / spectrum?
The author tried 50 steps with spectrum; results look OK but it still outputs video requiring frame extraction, and there is banding. They want tips to fix the banding.
