What is VideoUpscaler?
VideoUpscaler makes short, soft or low-resolution clips sharper with a fixed 2× AI upscale. Pick an MP4 file, compare before and after frames, and save the result if it looks better.
It runs the Anime4K neural network with WebGPU and WebCodecs on your own device, so the video is not uploaded to a server. There is no account and nothing to install.
