NVIDIA's one-step refiner turns low-res video into 4K in seconds
NVIDIA just introduced SoL-Refiner, an AI model that transforms low-resolution video drafts into crisp 4K outputs using a single denoising step. It works across different base generators, slashing MiniMax H3 generation time by 27x down to under six seconds. While it supercharges high-res rendering, it does alter or reimagine some fine details from the original clip.
