@peertube is the Fediverse's video sharing network. You can follow and interact with PeerTube accounts from Mastodon.

For example, you can follow @theatticdwellers and when they publish a new video it will appear in your Mastodon feed. If you like one of their posts, that will show as a thumbs up on PeerTube, and if you reply to a post it will show as a comment under the video on PeerTube.

More info about all of this (and also how to publish your own videos) at:
