MiniMax H3 shows severe banding in dark scenes, creator reports
itchplease · reddit · 2026-09-28
A video creator reports pronounced banding with MiniMax H3 in dark scenes — skies and smooth gradients, especially around the moon and in the darker parts of a night sequence, with example frames attached.
He also hit a second artifact: a bright halo around characters against dark backgrounds. He's asking whether others have seen this with H3 and for fixes, whether in ComfyUI or in post.
