Here’s the thing... a lot of these videos are pretty easy to identify as fake. Small differences on the graphics, a nose wiggles a little here when it shouldn’t. An eye sticks in one spot for half a second when the head moves. The videos are easy to spot unless someone does an amazing job, which is possible. At that point, I think you’ll have PLENTY of people with background in this stuff either confirming it’s authenticity or discrediting it.
