Did I lose you yet? Probably did but I'll keep going anyways. For a second lets say you do not it fact have an underwater green screen at your disposal, which I doubt these people had, you would have to follow all the steps aforementioned above WHILE also having to ROTOSCOPE (not going to explain this daunting video editing technique, google it) the Entire footage from the point in which the dude is underwater and until the end of the second encounter. I don't know about you, but as a graphic designer I know how difficult it can be to rotoscope such footage and to accurately roto out the motion blur caused by this guys hand movements. Let's take it a bit further and say that if in fact he couldn't get a hold of a green screen and would have to roto out the footage, the underwater bubbles generated from his movements would make 3D tracking this footage a complete nightmare.
Now that you know the necessary skill level needed to pull something like this off, I can safely assume that this guy does not work for Pixar nor has the budget to afford such video editing or would be willing to waste months of his time putting together a technical masterpiece of this magnitude only so that retards on the net can embellish their idiocy by labeling this as fake.
