If you're publishing to #PeerTube, bear in mind Mastodon will show your videos as made by your PeerTube account, and not your PeerTube channels.

To avoid confusing Mastodon followers, you might want to brand your account and channel identically. If you need to have several different PeerTube channels, consider using several different PeerTube accounts instead.

The username on videos viewed from Mastodon will be your PeerTube account. Channels will just look like groups boosting your account.
