SoL-Refiner, from researchers on NVIDIA's Sana project, is a one-step video refinement model: feed it low-resolution output from any video generator and it produces sharp 2K/4K video with a single denoising step.
Key points:
- One step, 8.91x faster end-to-end
- Plug-and-play with any base video generator
- Paper on arXiv (2609.37969), demos and weights live on Hugging Face
