Modular MiniMax H3 workflow enables seamless ultra-long video with segment regeneration
wjc_5 · reddit · 2026-09-08
A Redditor shared a modular MiniMax H3 workflow for multi-segment video generation, seamless transitions, continuation of existing footage, and single-segment regeneration. Key details: Motion Context overlaps generated content for near-invisible joins (at the cost of shorter merged duration); an official Add Guide node plus a custom Audio Guide Feather node handle continuous speech and ambience; dual sampling reduces size drift but can cause slight frame shifts; 0.45 denoise on reference images controls color drift between segments; audio refinement uses 0.3 denoise. A full YouTube tutorial is available.
