Is it possible to post a video to a community using PeerTube?

I see people sharing links to peertube, youtube, streamable, imgur, and other sites in communities in order to share videos. For the non-federated ones, it's understandable if there is no option, but for content creators, is it possible to share a video directly from peertube into a community?

I don't know if it's possible by adding @peertube@lemmy.world for example in the text of a description and then removing it or doing something else.

The goal here is that when sharing the video, the comments on the video are also sent to the video's page. Is that possible?
