This post provides a hands-on comparison of three popular upscaling solutions—LTX 2.3, RTX Super, and SeedVR2—for low-resolution (0.5 MP) videos generated by MiniMax H3.
Key takeaways:
- LTX 2.3: Reasonably fast but noticeably drops quality, softening details compared to the original.
- RTX Super: The fastest option by far, with visual quality on par with or slightly better than LTX 2.3.
- SeedVR2: Delivers the best overall quality with cleaner details and textures, though it is the slowest of the three.
