Technical Hurdles Suggest Extensive Z-Film Alteration Highly Unlikely

[Jan Klimkowski]

These are two gifs (same footage, one slowed down). Jackie and Clint are mostly stabilized in both clips.

They sync Nix and Zapruder.

Sync points are Clint's right leg at the beginning and Jackie's elbow contacting the limo trunk (look closely/repeatedly through the bush) at the end.

The FBI determined Z's camera running at 18.3FPS and Nix at 18.5FPS, basically a 1-1 ratio.

I stopped it at Z411, because from that point to where Jackie sits/slides down in her seat is 6 frames or 1/3 second.

She is much to elevated (Nix view) with her elbow braced on the trunk, to accomplish the slide in 1/3 second. imo

That particular Nix segment ends there.

Chris - fascinating and provocative.

OK - just for absolute clarity, can you confirm that I am undersanding certain points correctly.

1) When you write that these are "sync Nix and Zapruder", you are stating that you have lined up the starting point of both clips on a moment in real time and space in Dallas.

2) In this case, the starting point in real time and space in Dallas is "Clint's right leg at the beginning and Jackie's elbow contacting the limo trunk".

3) From this sync point onwards, we are watching the same snatch of space and time from two different vantage points: those of Zapruder and of Nix.

4) The FBI state the running speeds of the two cameras are nearly identical, so the movement of Jackie and Clint should be almost identical in time and space, with the only difference being the vantage point.

5) Your conclusion is: "She is much to elevated (Nix view) with her elbow braced on the trunk, to accomplish the slide in 1/3 second. imo".

Am I understanding this correctly?

If so, is the logical conclusion that the movements of Jackie across the back of the car in Dallas time and space occur more rapidly in Zapruder than in Nix?

In other words, if points 1 to 5 are true, then either Nix or Zapruder has been altered?
