Are there statements from Kodak employees who saw the Zfilm friday?

Based on your film knowledge, if these "transitions" were removed along with the rest... how would you know?

My THEORY here is that at least 928 frames at 48fps (19.3 seconds of film) were reduced to 354 frames (486-132) at 18.3 (19.3 seconds of film) by removing 574 frames of 48fps film. Please prove this is not possible..."

Although I'm not aware of anyone specifically asking Zapruder what his thought processes were when he was filming, it certainly looks like he began filming and then noticed that the presidential vehicle was not directly behind the lead vehicles, so he stopped filming and then restarted as the limousine came into view (Z133). In the space between these two shots, he may well have switched the frame rate, and so Z133 could have started a sequence at 48fps. (but, I would argue that this rate would then have had to remain constant through to last frame at Z486). I cannot see anything within the frames that would suggest the frame rate was adjusted - and also any resulting disruption I believe would reveal itself, even after removal of frames, because the disruption would occur over multiple successive frames (particularly at 48fps) and their removal would have produced a visible jump as Zapruder panned following the limo. That is, the extant film could have been created by a "dropping 2 frames keeping 1, dropping 2 frames keeping 1" formula - but there is no allowable place to remove a run of successive frames without that calling attention to itself. Having done step-printing, I found that even a single frame too little or too much can disrupt a rhythm.

Past that, in terms of what could or could not be done with an optical printer at, say, Hawkeye works - that facility would have a guy just like Ralph Pearse at NPIC, who would lay out some basic information about what was and was not possible. Based on my own experiences with optical printers, I think I know some of the things he would point out. I'll share those if someone is interested.

Jeff - you having some experience with film makes this especially important that I explain the process...

Thought I did this once, these are frame #'s:

Film #1: 1 2 3 4 5 6 7 8 9 10 48fps
Film #2: 1 4 7 10 16fps


The frames 1, 4, 7 & 10 are identical in both films.
Remove 2,3,5,6,8,9 from the 48fps film #1 and project at 16fps... the two films are identical EXCEPT for a 1/24th of a second difference in the IS area

Film #1 has frame 3 prior to 4, while #2 has frame 1 before 4... can you determine if there is a 1/24 of a second difference in the IS area images from frame to frame?


Example 2:

Film #1: 1 2 3 4 5 6 7 8 9 10 48fps
Film #2: 1 3 5 10 16fps


In this example something in frames 6-9 needed to be removed... the result? Greer's head snap, JFK's unexplained exaggerated back and to the left...or any number of things...
but the same # of frames are removed, the timing of the scene is the same yet there would be a pronounced jump... which we do indeed see during z302 thru 304.

Looking at this composite - it is simply not physically possible to move his head from frame 302 to 303 the distance he does in 1/18th of a second.
In fact the analysis showed it to be at least 50% faster than a young, prepared, althete could do.

Furthermore, anaylsis also shows that both foreground and background are in focus in these frames... another impossibility as Zapruder pans.
------

It is also obvious that frames surrounding the headshot in Muchmore were removed as well...

As Hill is jumping to the limo.

The gif is anchored on JFK's head... in this gif it does not appear as if the brakelights are on.... idk.

If I am missing frames please let me know - yet I find the same thing in the movie as well.
