MiniMax H3 Lip Sync Flaw: Mouth Moves During Instrumental Passages, Measured and Workarounds Provided
Prestigious_Cat85 · reddit · 2026-08-26
A Reddit user conducts a detailed test of MiniMax H3's lip sync in music videos, finding that during instrumental passages the model still moves the singer's mouth at half amplitude, despite perfect audio sync. They quantify the issue with frame-difference analysis, try various fixes (including scheduler adjustments) without success, and settle on a structural workaround: cutting to shots without the mouth during instrumental gaps. They share their measurement script and pose questions about turbo LoRA, step counts, and latent-level conditioning.
