Wrote a very long reply, and lost it when starring your post… :-(
In short: Thanks for all the great info and went down quite the rabbit hole with that link to your post, that linked to another person’s post. Great discussions happening there. :-)
But it seems like Friendica or RSS might be the way to go. It’s not about posting videos to Peertube from Mastodon, but about having a hub to follow and interact on other networks like PF, PT, Lemmy, Kbin, FF, etc.
Thanks again!
Thank you for your kindness.
