How long does it take to alter hundreds of frames of film?

[Royell Storing]

This is what I was talking about, delusions of self grandeur are rife in your community.

This was explained to you in the other thread, as soon as images are combined in an optical printer you have a degraded image with additional layers of grain. The special effects in movies at the time were locked off matte shots or blue screen work and not suitable for Zapruder type alterations.

The following two frames were filmed directly on set but the robots fighting picture was processed with multiple passes through an optical printer for added special effects like lasers and starfields which creates a much softer grainier image whereas the Zapruder film was just exposed once on the correct film stock.




The Zapruder frames reveal no build up of Film grain and thus the film was exposed in Zapruder's camera.



As soon as even one frame is removed you introduce an obvious stutter but throughout the Zapruder film is silky smooth. In the following gif only one frame was removed and the resulting lack of fluidity is plain to see.



You do realize that blackening one frame requires the exact correct pigment of black to match the surrounding level of black and then  when you start a series of frames then you have to consider how your black is affected by the movement and constantly changing lightsource that have a direct effect on your black, so in other words without advanced computer cycles to calculate the various intensities of black you're not going to provide anything close to photorealistic.

Or maybe because an 8mm camera only takes a limited amount of film and Zapruder had already used some of the film so was simply saving film for Kennedy.

       Instead of doing your Hokey Pokey Routine with regard to the Middle of the Current Z Film, why Not start at the Beginning of this Black Hole of a Motion Picture? The BEGINNING. The Time Warp/GAP we see at the beginning of the Current Zapruder Film is contrary to what we are told by both Zapruder & Sitzman. They could see the JFK Limo coming down Houston and were filming as it turned onto Elm.

Sure you are. And Rob Caprio is the Lucasian Professor of Mathematics.

I recall someone trying to tell an actual physicist back then that Kennedy was hit from the front and he responded with 'No physicist would tell you that'

And I wonder why Trojan hasn't prepared a white paper and published amongst his peers. Oh, wait.. his peers are the rest of CT wonder world where everyone becomes an instant expert in anything & everything.

I can't wait for his press conference.

Come back Lamson, all is forgiven.

If one starts with the premise or belief that "they" (the conspirators and actual murderers of JFK) can do anything, that there are no limits to "their" power and resources, then everything follows logically from there.

It doesn't matter whether the technical experts said the Z-film couldn't be altered with the changes unnoticed; it doesn't matter that forensic pathologists say that JFK's body couldn't be altered without the changes being noticeable.

Those experts are either corrupt or ignorant as to what "they" could do. And the evidence for this is that "they" did it. That's all that matters.

In conspiracy world everything is evidence of the conspiracy. I used to be a CTer and that's how I looked at this.

By my count, there's at least the Zapruder, Nix, Muchmore, Bell, Bronson, Dorman, Hughes, and Towner films that show JFK in Dealy Plaza.

To those of you who believe the Zapruder film has been altered, it might help everyone to understand your position if you could tell the rest of us two things:
*  Which of these films do you believe have been altered ?
*  Which of these films do you believe have not been altered ?

Many thanks...

To build upon your questions (and hopefully not to distract from them) how would "they" - the people who altered the Zapruder film - know that they didn't have to alter these other films? In other words, wouldn't they have to view the films first to see if what the films showed exposed their alterations of the Z-film? Is there any evidence that these other films were taken by "they" and viewed?

And how would they know exactly how many other films there were? What if they missed one? Or three?

As Josiah Thompson explained:

"[T]he critical problem for anyone thinking of altering the Zapruder film is not the Muchmore and Nix films. It is all the other films you don't know about - films developed outside Dallas by people from out-of-state who just happened by...or by foreign tourists who would get their films developed in their home countries. Any one of these unknown films could expose your alteration."

I disagree that the "unknown" is the critical problem. But it's certainly a major one.

There has to be some limits to what "they" could do?

Anyway, back to your questions first. Mine can wait for later <g>.

LOL !
You're not distracting from my point - you're making my point.

If someone says that one or more of the other assassination films - other than Zapruder - are authentic
    Then the burden is on them is to show the inconsistencies between that unaltered film and the altered Z-film...we should be able to see the inconsistencies, right ?

If someone says the opposite, that in addition to Zapruder none of the other films are authentic
    Then the burden of proof is on them to show how films like Muchmore or Nix are in perfect sync with the Zapruder film - yet somehow were publicly available within days after the assassination despite going through very different chains of custody

If the alterationists can demonstrate how either one of the above is even *possible* - let alone probable - then I'll be the first guy to listen.
If they can't, then what they're suggesting has no possible basis in fact, and I tend to disregarded it as illogical...

            With regard to the " very different chains of custody" claim raised above, it Must be remembered that back in "63" KODAK basically held a Monopoly in  Film Developing. Kodak frequently partnered with the U.S. Govt dating back to at least WW2. The overwhelming vast majority of JFK Assassination Films/Images were Initially "handled" & "developed" by Kodak.
