It's actually surprisingly easy to host your own instance, and if you don't allow anyone else on it then it's also very cheap, the cheapest VPS is good enough. I do the same thing, I have a cooking channel, a music one, one for family videos and one for Peertube Admins. I would have the same problem as you finding the right instance.
Peertube
A free software to take back control of your videos
Peertube is an open, federated alternative to Youtube without advertising or tracking. On this site, you can find a good Peertube instance, with good rules, good moderation and most importantly a friendly community.
I feel the exact same way. I just made my own instance and divide up my content. Each sub community is like a different interest of mine.
I reset it though and pauses federation due to the prior fiasco regarding the malicious images/users.
But, I really love the idea of having a personal Lemmy and in my previous run it felt like it was still gathering connections authentically. Although bigger instances won’t necessarily federate, but that’s not that necessary
I think you misunderstood, he posted in !Peertube@lemmy.ml so I guess he/she meant that they couldn't find a PeerTube instance which would allow all different video clip contents they are posting.
