I do believe we are talking about deep fake on the Trump video - it seems like a manipulated video tome, but that's not really the point I want to make. What just occurred to me is much more sinister.
My theory is that deep fake is how they are going to prop up Biden. Think about it. They can post videos of him speaking - saying ANYTHING they want him to say. He doesn't even have to be coherent for the next 4 years. They can hide him in a closet and push out a video from time to time, saying he's afraid of Covid, so that's why he's not seen out in public.
I worked in compositing and vfx. Hard to tell from how compressed it is as there's so much blockiness and smearing and those appear in all videos shot in the same area in similar way. The artifacts others are pointing to as being smoking guns I'm seeing in other videos trump uploaded that we know are real (points of high contrast and under his neck). Possible image background maybe, just nasty compression.
To me, the thing that is most off about the video is the body language and stiffness. Trump is a bit tight and rigid but he tends to make larger and quicker sharp movements when he changes position. Less assertive movements in the last one if you compare them with other videos.
just my 2¢, but I"m honestly not putting much effort into this video as I think people are giving it way too much weight
the video quality and artifacts are very clearly the dead giveaway.
literally every feed is 360p or very clearly upsampled 360p which is why it's so fuzzy.
looked around and haven't seen a single copy that's not clearly lowres or poorly upsampled.
then why are real trump videos like that?
there was a single one a week ago that looked like that. prior ones do not.
