In fact I'm 99% sure that Wilt could dunk from the free throw line.
However... that doesn't indicate that such a strategy of making free throws would be viable in a game.
1) He'd need to take off from behind the line. If he stepped on the line he would commit a violation. He would have to practice quite a bit to take off at the right spot.
2) He would get tired dunking the ball from the FT line 10-15 times a game.
3) How would it work on the second free throw when the defensive players would enter the lane to get a rebound?
There is no such thing as a "proof" in the scientific or historical community, just bodies of evidence. Only in the world of math is there such thing as proof, and we aren't trying to solve a mathematical problem here.
This body of evidence is very strong. Footage would make the body of evidence even stronger but it isn't necessary, as the body of evidence is already much stronger than anyone who might try and take a stance that such events never happened.
