You can do a local recording with zoom, you can have a meeting by yourself, share screen, and then position the camera where you want it, and record. when you finish the recording and the meeting, the file will be processed and saved on a local folder without doing anything else.
I consider that the easiest method.
Dislike: there is still no way to group communities into sub feeds, apart from subs, local, all. (and the work around some do of having multiple accounts seems silly to me)
