The entire background is fake -- it's like a zoom meeting where you select the background from a photo to hide your true location.

His shoulder on the right-side of the video is more blurry than the left side.

BIden's eyes in reality are blue, yet they're dark brown in the video.

Watch the lapels of his jacket. They waver as he moves.

There's pixilation going on between the red carpet and the upper arms of his jacket, and also around his head.

Not the slightest motion with any of the flags -- no air currents at all??

Definitely a deep fake.
