Fixing blurry text in MiniMax H3 videos: per-frame SAM3.1 inpainting workflow hits wobble issue
OkSilver7237 · reddit · 2026-10-26
A creator documents fixing blurry text in MiniMax H3 video: 1MP 35-step pass plus 2MP latent upscale yields decent visuals but unreadable text. Per-frame inpainting with FLUX 2 KLEIN and a sharp-text reference makes text sharp but introduces frame-to-frame position wobble. An improved workflow uses SAM3.1 to auto-mask the product per frame plus edge detection for precise inpainting; the full workflow is shared, with the author seeking a fix for cross-frame alignment.
