I saw this video posted to Reddit the other day, depicting who was claimed to be Joe Biden interacting with 10 different families. The video is rather disturbing and uncomfortable, so I warn you before watching. Here is the video: https://i.imgur.com/BW6SOhC.gifv
Given the proliferation of Deep Fakes and the prevalence of misinformation, I wanted to know for sure, is this Joe Biden throughout the video, and is this video doctored in any way?
Edit: I understand the video was edited in such a way to disgust (for example, the lack of audio in the first scene removes the child's laughter as @Barry Harrison's answer reveals). What I am most interested in is can we be confident this video is unaltered throughout, or are we able to say "at 1:40, the hand is not Biden's" for example.
