ComfyUI Tutorial: MiniMax H3 2-Stage Workflow for High-Res Video
cgpixel23 · reddit · 2026-08-29
The author presents an optimization workflow for MiniMax H3 designed for low-VRAM GPUs like the RTX 3060 6GB. The method uses a two-stage sampling strategy: generating a low-res video first to save time and VRAM, then using a second upscaling stage to reconstruct it at high resolution with added details. The tutorial integrates optimization nodes like Low VRAM Attention and Chunk FeedForward, and compares MiniMax H3 sampling with LTX sampling.
