I'm interested as well. How did you choose your PeerTube instance? What happens to the videos and followers if whoever runs peervideo.club stops what I assume is a side project of them?
My understanding is I could backup (no plans), and restore to another instance. To take my followers with me I would have to leave peervideo.club in a more planned way and set my account to redirect to another. No idea how long the redirect would have to stay up for most of my subscribers' instances to get the message. Even with federated you need some degree of trust that you won't be kicked off or have you instance shut down with no warning.
