The Nix and Zapruder cameras had different frame rates. So somebody made them match up.
John, what you don't seem to understand is that if you have two different cameras capturing the exact same scene and each one is running at a different frame rate, you
can't [edited] change what's actually being recorded just because one or the other has more frames going through the gate.
The NZ sync video I posted proves that.
But for argument's sake, let's say that in Z for example, some frames were removed. What exactly was removed...in other words, what was so dastardly that some frames needed to be removed? No one for the past 55 years has ever been able to answer this question.
To be honest, I'm really surprised that you brought this up, John. You seem like one of the more level-headed ones around here.
