Relationship of rifle location to TSBD corner.

6sec x 5.49ft = 32.94ft + 52.5ft = 85.44ft

3+29.2 - 85.44 = 243.76

6.25ft (the approx distance between the TSBD snipers nest (2+50) and the TSBD building corner (2+43.75)

Two distances based on whole frames:

(3.74mph) 5.49ft per sec / 1.01666... = 5.4ft per sec whole frames

btw, the conversion/difference of 109.95 frames at 48fps = 2.29 sec x 18.3 fps = 41.91 frames

Mr. SHANEYFELT. Yes; we have established that the Zapruder motion picture camera operates at an average speed of 18.3 frames per second. And we have been advised that the minimum time for firing the rifle in successive shots is approximately two and a quarter seconds. So this gives us then a figure of two and a quarter seconds of frames; at 18.3, this gives us this figure of 41 to 42 frames. 
Representative FORD. Would you repeat that again, please? 
Mr. SHANEYFELT. The camera operates at a speed of 18.3 frames per second. So that in two and a quarter seconds it would run through about 42--41 to 42 frames. 
Representative FORD. Then the firing of the rifle, repeat that again? 
Mr. SHANEYFELT. As to the firing of the rifle we have been advised that the minimum time for getting off two successive well-aimed shots on the rifle is approximately two and a quarter seconds. That is the basis for using this 41 to 42 frames to establish two points in the film where two successive quick shots could have been fired.

And to bring this full circle... the reason for the splice there - imo - is to hide the wide Elm turn...  by using the earlier motorcycle as a guide we can see how many frames it takes when disappearing into that corner...  Since the cycle is not stopping, nor slowing much... the 81 frame count is low compared to the 109 removed...  we are also to remember that the motorcycle is already within the turn at frame 20-40 while the limo had not yet entered the picture by frame 132.

 

now we take Position A and compare it to where the cycle is in frame 121...  yet somehow, the limo is in the middle of the road at 133...  I know I posted this before, this approximates that turn, the divergence of paths, Pos A and then back to 133...

(note:  For reference, Roy Truly testified to the limo almost hitting the Elm extension curb and having to turn sharply left to get back to the middle of the street
Mr. BELIN. The street leading to the expressway, that diagonal street? 
Mr. TRULY. That is right.
And the President's car following close behind came along at an average speed of 10 or 15 miles an hour. It wasn't that much, because they were getting ready to turn. And the driver of the Presidential car swung out too far to the right, and he came almost within an inch of running into this little abutment here, between Elm and the Parkway. And he slowed down perceptibly and pulled back to the left to get over into the middle lane of the parkway. Not being familiar with the street, he came too far out this way when he made his turn. 
Mr. BELIN. He came too far to the north before he made his curve, and as he curved--as he made his left turn from Houston onto the street leading to the expressway, he almost hit this north curb? 
Mr. TRULY. That is right. Just before he got to it, he had to almost stop, to pull over to the left.
If he had maintained his speed, he would probably have hit this little section here.

Jim DiEugenio: 

"The other thing that Sprague was interested in, is he want to set up experiments about the single bullet theory, and he was going to do them in public, except they were going to be real experiments, not set ups like the FBI did for the Warren Commission. And he was going to invite the press there, he actually announced that. And he was going to hire independent investigators, he was not going to use the FBI and the CIA, and he was going to have independent medical doctors. And he had a fleet of I think 13 lawyers. One of the first things he did is that he did a review of all the photographic evidence. And according to Al Lewis, that lasted almost all day, for about 6-7 hours. And before the presentation began, Sprague turned around at all the aides there and said, "I don't want anybody to leave unless I leave, and I don't plan on leaving." And so Al Lewis told me that when those presentations were over, out of the 13 lawyers, 12 of them did not believe the Warren Commission anymore. And I talked to one of the investigators, L.J. Delsa, and he told me that when they looked at the Zapruder film and the autopsy evidence, he concluded, hey, something's really screwy here with this autopsy evidence and the Zapruder film.

So in that phase, under Sprague and Tanenbaum, those guys were really looking at the Kennedy case like a homicide. They were really looking at the hardcore evidence. That is the autopsy, the Zapruder film, the photographs, and they were leaning towards the critics. And so the Warren Commission was really under siege then. But the media began to attack Sprague incessantly. I think there was a five part series in the New York Times."

Tactics sound familiar, Walton?

Playing the Towner frames at 22-24fps looks ridiculous.  (what speed did you do your FLV files of the Towner turn?)

You'll have to show me which one in particular, I've created quite a few.

So in the end, the MATH follows the hypothesis that IF the film was altered... a methodology would have been employed...

Well spoken.

Chris' thoughts on this methodology are spot on and take a difficult process and makes it very simple...

Fortunately for a few, but not for the majority.

 

 

 

 

Thanks David.

Next, I'll introduce what I believe the pre z133 total frame breakdown would consist of.

Chris, when you get through with all the computations, I think it would be wise to start a chronology of the Z-film, noting WHERE in the film the frames were deleted and how many at each deletion, as well as you can possibly ascertain.  Then tie these frame deletions to the corresponding flim-flammery of the data blocks as surveyed vs. data blocks as entered in the WC report.

Mark, a film shot at 48fps slo-mo with sequential removal of 1/2 the frames and then a sequential removal of 1/4 of those remaining frames yields this result:

https://drive.google.com/file/d/0BwrExtVD005OeFhFSHkxOTU5dG8/view?usp=sharing

Did they extract all the frames exactly sequentially? Who knows! We don't have the true original.

The final (whole frame) ratio of 18/48 = .375 = the combination of sequential removal of 1/2 the frames and then a sequential removal of 1/4.

I would suggest viewing my version which is representative of the above frame removal sequence, then viewing MPI's version for comparison purposes.

I think a well-written version of what you believed happened, and where/when/why, would make a good narrative to explain how Spector & Co. got from 3 shots/3 hits to the magic bullet/SBT, and would explain why the problems exist in, for example, explaining Clint Hill's superhuman speed if the motorcade didn't slow to nearly a stop.

A version of what I believed happened is speculation. 

For every frame seen in the extant film, a 48fps version would yield 1.622 extra frames per existing frame. Remove those 1.622 per every frame and I'm sure you could hide what was necessary. 

Something superhuman on film would equate to excess frame removal (even moreso than 1.622) unless something along the lines of David Healy's (optical printer primer) input was used also. 

You have outlined things well. Perhaps My Josephs might collaborate with you and write the narrative, because your work seems to come off at this point as staccato bursts, rather than as a flowing tale of deceit that this truly is.

Maybe.

I'm sure David J. would like to exhaust most, if not all other alternatives before a narrative is written. Imo

Staccato bursts?    Fair enough.

Easier for me to implement TMI initially, and then reconstruct in a somewhat more chronological manner.

Unfortunately, this is the way I have discovered it.

IMHO, the information you have uncovered here neither convicts nor exonerates LHO... but it certainly convicts Shaneyfelt and Spector of evidence tampering, IMHO.

Agreed. Never was my intention to either convict or exonerate LHO.

If you believe it indeed convicts Shaneyfelt, Spector and the like, thank you for the support.

My analogy being: 

If the Police, DA, and Judge among others are caught tampering with evidence, sometimes the convicted (regardless of guilt or innocence) are set free.

Added on edit:

If you watch the version I created, notice the frame number count and the ghost numbers within, which are just an indicator of the extra 1.622 frames that were there originally.

Another easy way to prove the 18.3 fps frame rate is bogus would be to plot JFK's position from z133-z166.

Use the LOS from the Z pedestal to the background lamp-post (frame z166) along Robert West's path.

35.90ft / 1.803 sec (33frames@18.3fps) = 13.54mph

 

 

 

 

 

 

 

If you want to see how the difference in distances would basically align, just subtract 5.49ft from the above distance of 35.9ft = 30.41ft. 

Then take a look at the distance Myers has it traveling from Towner end to Z150 = 24.96ft and add that 5.49ft back = 30.45ft

Close enough!!!

With speeds of only 16 and 48 on the "Sears Tower Varizoom 8 mm color motion picture camera"... how do they get to 24fps?

 

Not sure about the question.

Who or what are you referring to in the context of 24fps?   Myers with Towner?  WC with the extant zfilm?

Residual 24fps is just a variation of a 48fps slow-motion origin, cut in half.

Myers uses 22.8fps as it accommodates his 1.8 sec jump to z133 and then a 5.49ft per sec slow down syncing with a 18.3fps final rate.

After all is said and done, the overlapping part of the zfilm with Towner will never see the light of day, therefore, the frame rate of Towner becomes inconsequential to the powers that be. Myers just does us a big favor by providing enough data to reveal the farce.

Keeping in mind the splitting of the limo path which we discussed previously.

35.90ft / 1.803 sec (33frames@18.3fps) = 13.54mph

Dale Myers average for limo from Towner End to z150 = 9.8mph

Difference = 3.74mph

If you wanted to use the average of 9.8 and 10.5 = 10.15mph to cover thru z166, the conversion would be:

10.15 x 1.016666... x 1.3114... = 13.53 mph

It's that simple to show the Zapruder film was not shot at 18.3fps.

Myers project was supposed to be a frame x frame sync of multiple films using Z at 18.3fps. 

Can't have a sync when your speed for the limo in a 33 frame stretch is off by 3.74mph.

This is basic math.

https://drive.google.com/file/d/0BwrExtVD005OdUpkeGs2R3lxYVk/view?usp=sharing

 

 

 

 

 

 

 

If you want to push this farther up Elm St 

Towner fps via Myers 22.8 - 18.3 = 4.5fps difference

Myers (1.8sec) = 33frame jump / 4.5 fps = 7.333...sec x 18fps (whole frames) = 132 frames 

Limo on film at z133.

Overall, Myers (9.8mph) 14.42ft per sec rate of speed when broken down into distance:

1.803 sec x 14.42ft per sec = 25.999ft

1.803 sec x 5.49ft per sec.  =  9.898ft

Combined distance             =  35.897ft = plotted distance (35.9ft) from above.

Glad that sunk in.

If you have a good grip on the ratios, you can then plug them into other parts of the overall scenario such as:

1 - .625 (1/2 + (1/2 x 1/4)) =.375 difference x (18.3/18) = .38125 = 18.3/48

Or cross-multiply: .375 x 18.3 = .38125 x 18

Or whole frames: 1/.375 = 2.666... x 18 = 48 frames.        1/.38125 = 2.6229... x 18.3 = 48 frames

An obvious reason for using 18.3fps as the final frame rate.

On 6/26/2017 at 4:36 PM, Chris Davidson said:

The above ratio should help you understand in terms of limo speed conversions too. 

Example: CE884 WC final plat: 14.94mph (z168-z186 = 21.6ft @18fps) x .7625 = 1 / (48/18.3) / 2)  = 11.39mph / 1.016666667 = 11.2mph = Shaneyfelt testimony = average limo speed z161- z313.

CE884 (z208-z255) there were no background landmarks to use in measuring this span, yet:

47frames @ 43ft @ 18.3fps = 43ft / 2.568sec = 16.744ft per sec = 11.39mph

Remember there was an adjustment made between the public version CE884 and the final plat version CE884 among frames z208-z210.

Paraphrased:  The original sequence of 168-186 = 3+29.2 thru 3+50.8 = 21.6 feet in 18 frames = 1.2' per frame

21.6ft converted to a full second from 18fps to 18.3fps = 18.3/18 = 1.016666..  x 21.6 = 21.96ft per sec.

Sorry, I cannot find reference for the ".7625" you are using...  what is that?

Determine the limo speed after you remove the first 50% of total frames from a 48fps slow-motion film.

But there are 18 frames from 168 to 186.  You're using the result of determining the distance per frame filming at 48fps... yet you use 12... why?

Dealing with one whole second, the equivalent number of frames removed from a 48fps film equaling 5.49ft, is 12 whole frames.

12 frames @ .4575ft per frame yields the common difference distance of 5.49ft.

Remember Myers: http://educationforum.ipbhost.com/index.php?/topic/9975-splice-in-tina-towner-film/&do=findComment&comment=354306

That 5.49ft per sec common difference equates to 3.74mph

so .7625 = 11.2 mph ...   please explain...

1/1.3114 or   .7625 x 48 = 36.6 frames x .4575ft per frame = 16.7445ft per sec / 1.47 = 11.39mph / 1.01666…(18.3/18) = 11.2mph

IDK = 1/reciprocal of IDK = 48fps/18.3fps (2.623) / 2 (first 50% cut) = 1.31147 x 14.94fps mph = 19.59fps mph = 11.39mph / 1.016667 = 11.2 = FBI speed during crucial frames

What is representative of the limo speed after removing 1/2 the frames to begin with?  2.622 / 2 = 1.3114    1/1.3114 = .7625 

The limo is traveling at .7625 of its true speed.

This is equal to 18.3/24 = .7625
