MiniMax H3 Video Generation Plagued by Heavy Compression Artifacts
MrNiceJesus · reddit · 2026-08-13
A user reported encountering severe compression artifacts after switching their video editing workflow from Bernini to the MiniMax H3 Ref2V workflow.
- Degraded Quality: Even when saving outputs as lossless PNG image sequences, the resulting quality resembles a low-resolution MP4.
- Timing Mismatch: There are noticeable imperfections in video timing alignment.
- Verdict: Although MiniMax H3 offers better prompt adherence than other WAN models and removes the 5-second limit, the heavy compression and timing issues render it completely unusable for the user's professional needs.
