It's not exactly what you're after, as it's anime specific and you need to process the video yourself (eg disassemble to frames, run the upscaler, then assemble back to a movie file), but Real-ESRGAN is very good for cleaning up old, low resolution anime:

If you want to avoid manual processing, Anime4K runs in real time as a GLSL shader you can load into MPV (or Plex or something called IINA according to the readme) and still gives great results.
