Minimax H3 Context node tutorial: extend AI video generations indefinitely in ComfyUI
Hrmerder · reddit · 2026-11-11
Reddit user Hrmerder published a detailed tutorial (with three full workflows on Civitai) on extending Minimax video generations in ComfyUI using the H3 Motion Context node — no custom "Director" node packs needed. The node pulls the last x frames of the previous clip (configurable contextlength) as the latent for the next generation; you must trim the overlapping start of the new segment to avoid stutter, then concatenate. The loop can be repeated indefinitely (author claims up to an hour) with no extra VRAM. Tested on a 5080 16GB rig; a 3060 8GB should also work if the stock fl2vid workflow runs.
