Best ways to find videos hosted in a federated manner?

Hey everyone. I mod a sub which seeks video content. I've been posting myself and it's 90% youtube links. I see the irony of this and I'd like to surface 'fediverse' videos in my community if at all possible.

I see that Peertube is a thing. I've been able to search a bit for peertube videos on https://joinpeertube.org/browse-content - however I quickly run dry. Are there other ways to find / browse Peertube videos?

Are there other platforms besides Peertube I should be aware of?

Anything else you want to tell me about videos and fediverse? I'm ready to learn
