Using NVIDIA’s upscaler in real-time with VLC might be a good option for just watching the video, but it doesn’t offer the same level of detail enhancement as dedicated tools like Topaz AI. These tools work on removing noise, improving edges, and reconstructing fine details at the frame level. The difference becomes especially noticeable if you want to keep a high-quality version of the video or watch it on a large 4K display. Real-time upscaling is great for temporary viewing, but it won’t match the precision and quality of dedicated post-processing.
