Yeah if small quantity it’s not too bad to do your way. I use jellyfin so everything shows up ok for me, although it’s weird to see the “wrong” thumbnails.
For me I’ve got everything as a docker setup using https://docs.linuxserver.io/ They don’t have a tubesync one but I found they have good instructions for setting it up and that’s how I learned enough to do so on my own with tubesync. But there is def a curve there.
My perfect ideal would be freetube as a web server just for browsing where I could hit the dl button and fire off a download command to my server, then it shows up in jellyfin or Plex. I… Haven’t found a way to do this seamlessly yet, but I’m always on the lookout
