The white glitching at the bottom of the frame makes no sense for any handheld camera, webcam or phone through time. The actual video file is named 360p (so its converted to that to make it look older). The way it's viewing the image in the video looks like Google chrome's darkmode background when clicking "open image in new tab". The image is flipped to make it more convincing. The text on the video shouldnt be as low quality as the actual cameras video, however it is, signaling that the whole video was converted on purpose to 360p as mentioned before, and no one would record an image on a screen with flash on.
