It is not hard at all to launch PeerTube. (GitHub - Chocobozzz/PeerTube: ActivityPub-federated video streaming platform using P2P directly in your web browser · GitHub ). Those instructions will take you step by step.
If you do not want to be taken out of the forum, though, I cannot remember if PeerTube will render for you within the post. I like PeerTube because since you run the instance yourself, you can be an outlaw and post videos that are too taboo, offensive, and triggering for Vimeo or Youtube, like patriotic or religious videos. That would be funny if it wasn’t true these days.
Let me know if you run into trouble setting up your instance.
