It's federated like Lemmy, so each platform has 'local videos' and an 'all videos' section. E.g. https://fedi.video/videos/local and https://fedi.video/videos/overview
Of course, since it's federated, it means other platforms like PieFed, MBIN and Mastodon can access the same stuff, so you don't need to register anywhere if you're on one of them.
