It serves two purposes on a PeerTube instance: it ensures all videos can be played optimally in the web interface, and it generates different resolutions for the same video.
Other Framasoft's volunteers and salaried members also contribute to the PeerTube project on various aspects (strategy, communication, development, community animation).
PeerTube allows platforms to be connected to each other, creating a <strong>big network</strong> of platforms that are both autonomous and interconnected.
