I know that I wouldn't knowingly drive into your triangulation of snipers, would you?
No, I wouldn't. But what does that have to do with Greer's "orders" and whether he complied?
The proof of my film editing competence is on display in hours of Youtube videos and you?
And in addition, here on this site I have posted a stack of video gifs which all require some form of editing, from editing out redundant scenes, editing together time sensitive video collages all the way through to speed manipulation and you?

Everyone knows you are merely an armchair photoshopper with zero training in photogrammetry. So you equate video gifs with 8mm film? For that alone, you fail.
Anyway enough of your amateur gibberish, in Zapruder the reality is we are left with sequential film frames of Zapruder's pan which are all mathematically measurable from frame to frame and even with 1 frame removed the sequence instantly has a staccato effect.
I espouse professional gibberish, thank you very much. Unlike you, I actually put in the time to learn geomatics and photogrammetry, which I apply to my work every day. That's why I know you are a joke. Staccato effect, right!

Do you believe any frames are missing in this sequence? I set the animated gif to real time, which has Greer facing forward faster than the blink of your beady eye, mate.

Herbert an old member made a claim that the following woman had a frame removed at the time of the headshot but as can be seen in the video I edited and composited together, as soon as even 1 frame is removed it's instantly detectable. How about you prove your observations with something similar?
So you are comparing 1 copy of the Z film vs another?

Axe yourself why the FBI returned a copy to Zapruder and kept the original, which they sure as hell edited. There are at least 3 splices which cannot be attributed to Zapruder.
What? It's your claim and so far all you've got is some 2d stickman representation that isn't even remotely Kennedy's position. I thought you were some sort of photogrammetry wizard, this sort of stuff should be a walk in the park?
I know you are dumb, but not that dumb. You know damn well how the re-enactment works and you have already done it and were heartbroken at your results. It's the reason you stopped posting here, otherwise, you would have posted your results faster than a magic bullet.
Here are my results, sucka:
