So this video feels very vaguely fake. I dont know if you ever watched creatures of the fog ( there it was cgi ) but this has very similar feeling. Quality feels tad to low to be true, especialy in the age of 4k cameras in nearly every smartphone. It just screams fake and the channel dosent help since its only 4 months old
There is no such thing as being able to tell if something is AI with 100% certainty (there is even a game dedicated to it called HumanOrNot which I might be found playing), but the way it is described would seem to point to it not being made by AI.
