Has programs that upconvert stuff with ffmpeg
You'll want a version of ffmpeg with cuda compiled with it like:
https://www.gyan.dev/ffmpeg/builds
I use the full ffmpeg-release-full.7z of the lastest version but it seems
ffmpeg-release-full-shared.7z may also work on paper.
(trust ffmpeg takes a while to compile)
For Linux instructions the only method I know how is to build it yourself which you can do with https://colab.research.google.com/

Will find a pre-built binary eventually.
