RefMod's Likeness 'Breakthrough' Degrades MiniMax H3 Video Quality — Fix Inside

Kooky-Mode3047 · reddit · 2026-10-04

The author diagnosed why their MiniMax H3 videos suddenly became oversharpened and oversaturated: the new RefMod character-likeness tool slams reference images in as video frames, blowing past H3's documented input limits (≤9 images, ≤3 video/audio clips ≤15s, ≤12 mixed files), wrecking quality. Workaround: drop RefMod, use a 2x2 reference grid with native 1344x768, 15s, standard H3 sigma (12:3), seeds2 with the beta scheduler (.6, .6), and Spectrum to cut internal calls — 35 minutes per generation. Turbo LoRA users mask the degradation via heavily shifted sigmas.
