This video is fake, that has been established beyond doubt. But CGI, even "prosumer" CGI like this, is really getting better. Even at this level, people are relying on "hints" that a CGI transition has taken place - camera looks away, is obscured, or the picture is blurry. Give it a couple of years and those distracting-from-transition tricks probably won't be necessary any more. Then what?
- There is not point in that, images don't have value as evidence anymore, it'd just end up as an entertaining image that came from an unknown source at an opportune time.
