Welcome to the club! It looks like the other recommended solutions have a UI for browsing as well, which is cool. As it is my ytdl-sub feeds into a library for Emby so I personally don’t need another UI, but it is tempting. Only issue I could see is the sane one I had to fix: Some videos only had AV1 available, and support for AV1 encoding only begins at the very recent Intel Core Ultra and AMD 7040 CPUs. I have an RTX 3060 at my disposal for HW transcoding but who knows if those YouTube archiver/players support it
