MiniMax H3 native 20-step high-res video: sampler settings that work
Glittering-Cold-2981 · reddit · 2026-11-10
A Reddit user shares tested sampler settings for MiniMax H3 video generation at native resolutions above 3.7MP (e.g. 2560x1440) without Speed LoRAs: LCM sampler + Simple scheduler with shift 12/3 works best at 4.5MP, while Resmultistep and ErSDE perform worse. Setup uses BF16 models with both VAEs in FP32.
