Audio doesn't seem to match up either, further going in the direction of a green screen or being done on a "stage".

Everytime President Trump was doing an outside impromptu presser (on his way to board marine one) he had to yell and have the press yell back at him, as the nearby marine one was already spooled up and quite loud.

At the end of the video of the "2nd" angle you can hear marine one really loud when the camera pans towards it. Other than the two "fake mics" the others look to be using a cell phone to record the audio and not a directional mic, every ones audio would be poor and clipping if that is all they used.

Also it seemed everytime President Trump did one of these things there would be dozens of mics on poles (he called the sticks). Doesn't look like the media is even interested in biden and they had to photoshop in two haha.

It is really weird they would let something like these recent videos slip through the cracks, unless some one maybe is trying to send a message.
