I’ve tried a few peertube instances, peertubenz tilvids, makertube and a few others. I always run into a problem that I dont experience on mastodon or lemmy. I will follow a link and I will try and subscribe to that person from my peertube account and I wont be able to because whatever peertube instance im on doesnt federate.
I get not wanting to federate with every random server but I would have expected a decent network to have formed.
Maybe I have just been signing up to the wrong instances or am doing something wrong.

Peertube.wtf has been my savior in all this. But my tiny instance federates. I agree its a bit frustrating sometimes.
I think that many do not federate because they don’t want to deal with federation traffic + video traffic. Just FYI, my tiny raspberry pi equivalent server can keep up with both Noe for over a year ;)
Or they don’t want others to know they have illegal content. I’m not 100% sure why.
