ComfyUI Node Ports LTX-Style Latent Upscaling to MiniMax H3, 3x Faster Video
lumos_ai · reddit · 2026-08-21
A user shares a custom ComfyUI node that brings LTX 2.3-style latent upscaling to the MiniMax H3 (Hailuo 02) video pipeline, with a huge speedup.
The approach runs the initial pass at a lower scale (0.2–0.5) followed by a fast 3-step neural upscale, cutting total render time for high-res video from 10–11 minutes down to around 3–4 minutes while keeping facial details and motion clean. The project is available on Hugging Face.
