Peertube is part of the fedi. So is it possible for a peer tuber to post a video to a Lemmy or Kbin community?

I’m new to peertube. Before I upload a video that depletes a chuck of my bandwidth limit, I would first like to know if it’s possible to post a video on peertube and then /from peertube/ create a thread in the relevant Lemmy community or Kbin magazine. Or do I have to use a separate Lemmy or kbin account for that?
