I am currently trying to find a new AI upscaler so bear with me. I had a website that was doing it but they changed their system so it only works on videos 5 minutes or less.
So I switched to a free software from github but that suddenly started deleting entire folders of data for some reason. I'm not willing to risk experimenting with it to see what went wrong, because I don't want to lose anymore files. I'm lucky I didn't lose anything irreplaceable.
