How much could you alter the film if Abraham Zapruder had shot in slow motion mode?

[Chris Bennett]

If you speculate that the anomalies are caused by film editors alternating the pattern of deletion ( o x x, x x o ...) you could detect that by the motion of the limo against the background.

Thanks for your description, Drew.

If one shifted the pattern of deletion over time
(o x x, o x x, o x x, x o x , x o x, x o x, x x o, x x o...etc) over the course of hundreds of frames rather than the eight I show here, could you smooth out the motion and lower the chance of detection by comparing it to the limo against the background? I know that people have speculated about the actual running speed of the B&H camera as Zapruder was using it over the 26 seconds, how tightly it was wound, etc.

Also, would you discount the slow motion mode out of hand, or is it possible it could have happened as part of a larger alteration scheme?

Not trying to debate whether it happened that way, or even if it was altered at all. More trying to learn if it *could* have happened that way, if someone was trying to alter it.
