Go to the video preferences 'gear' icon and SLOW THE VIDEO SPEED PLAYBACK TO '0.25'. Much easier to see that THIS FAUX RALLY IS GREEN-SCREENED!!!
I'll go so far as to say the 'STRONGER TOGETHER' plackard on the podium is OVERLAYED into the video!!! There is an odd black frame around this sign.
Oooops. My bad. Upon further review this is NOT green-screened. She is standing in front of a large VIDEO MONITOR of a live audience being recorded ELSEWHERE.
This way, the large medical entourage she has at the ready immediately off camera cannot be seen by the audience.
