NVIDIA and MIT researchers released Open-H3-Regenerate-2K on Hugging Face, a video enhancement project based on MiniMax H3. Using LoRA fine-tuning and latent space amplification, the solution regenerates low-res drafts into up to 4K resolution, achieving ~3.9x faster inference than unoptimized versions and outperforming the official API in perceptual quality benchmarks.

    NVIDIA and MIT Open-Source H3 Video Enhancement with Native 4K Regeneration

    • Open-H3-Regenerate-2K supports native regeneration from low-res drafts to up to 4K (3840×2160).
    • Combines LoRA refinement with latent space amplification and SoL-Engine acceleration, reducing 5-second video processing time to 22.45s on a single B200 GPU (~3.9x speedup).
    • Outperforms the official API in UniPercept perceptual quality scores (60.0 vs 53.4) on RefinerBench-150.
