An area I have some concern about is the size of Texas Governor John B Connally during frames where he appears to be turning, as in some frame(s) he appears smaller than others. I never noticed any difference while viewing the film in motion, only in later years when I was able to look at individual frames on the internet. I try to always remind myself that I am not looking at people in any film or photograph, only images. There may be a logical reason, due to imaging, or I could be wrong.

[size=12]I have a problem with the turning shown on Z223/Z224 and Z224/Z225. These rotations are not preceded by a gradual acceleration nor followed by a gradual deceleration. In other words the film presents a snap, second derivative of acceleration, of the torso which requires two separate external forces acting about one eighteenth second apart.
I also note that a spectator on the north peristyle exhibits a humanly impossible motion of their arm on Z223/Z224.

In particular the arm rotates from their side by about sixty degrees without producing a massive motion blur.
