That clip doesn't exist to make money - it's not a MJ Nike commercial - it's nothing but 25 seconds taken from a low-budget documentary. There is ZERO incentive to fake it.
Why? Imagine this: Wilt did indeed sink 10 such shots in a row once. People saw that and thought to themselves: this should exist on film. So they made a clip. At the time the documentary was made, Wilt made some and missed some. So they chose to make the clip we see it. What we are able to watch now is a result of this. It is true and it is not at the same time. If anything, this is the most plausible scenario to me.
