Landrews-89 · reddit · 2026-08-05
A developer tested the MiniMax H3 video generation model on an RTX 5090 (32GB VRAM) and compared it with the LTX 2.3 upscaling workflow.
- Efficiency: Generating a pure text-to-video clip at 544x960 resolution takes about 9-10 minutes.
- Quality Enhancement: Upscaling the original clip to 1152x2048 using LTX 2.3 significantly improves clarity without destroying the original look.
- Verdict: The author was highly impressed by the motion and consistency of MiniMax H3, thrilled to run such a high-quality model locally on consumer hardware.
