Edit: I will say that there video could possibly be prerecorded. There are probably only a few people there with him, likely other priests or religious. This is not part of a Mass nor public. So it could easily be something that he wouldn't need to do live. That said in general his Sunday Angelus and general audiences are typically supposed to be live, but with COVID lockdowns it's anyone's guess.

Just took a look at the feed, that is definitely something that was prerecorded. Not part of the day's Mass, he's completely by himself.
