MiniMax H3 at 768x causes melting faces in audio-synced singing videos
PersonalityLimp2593 · reddit · 2026-09-02
A Reddit user reports that when doing ref2ref with audio sync (singing) on MiniMax H3 at 768x, about half of generations produce melting-face artifacts, likely from stretched low-res pixels. They ask whether insufficient reference detail is the cause, whether the newer 2k 3H flagship fixes the low-res issue, and about ComfyUI-H3-FaceRefine.
