David, That gif should give you a side x side speed comparison of walking vs jogging. This gif, overlays that difference for you.

I recently came across a publication by Tim Nicholson. If interested in more of his work, you can contact him at: tim.a.nicholson@gmail.com Tim is gracious enough to allow me to post excerpts from one of his academia papers. He used a more sophisticated method of determining frame removal and here is one of those excerpts pertaining to the above. I believe we've reached mutual support.

In case you don't understand what is being shown to you, here is an easier way to look at it: 2.24mph increase in speed = 1 frame removed, and so on and so on. You can check it a couple of ways related to the link above and the CE884 .3ft per frame listing of z168-z171 7.2ft x .3 = 2.16ft 7.2ft - 2.16ft = 5.04ft 5.04ft / 12 frames = .42ft per frame .42 x 18.3fps = 7.686ft per second / 1.47(1mph) = 5.228mph + 2.24 = 7.468mph OR 2.24mph x 3.333frames = 7.466mph The sequence starts sooner than z301, but I think you get the picture now.

Meant more along the lines of different floors within the same building allowing for different angles.

There's always the possibility of multiple shooters in the same building. It does not mean they all had to fire a weapon. http://educationforum.ipbhost.com/topic/26525-unveiling-the-limo-stop/?do=findComment&comment=421299

We are making great strides though.

A continuation from ITEK's tipoff: http://educationforum.ipbhost.com/topic/26525-unveiling-the-limo-stop/?do=findComment&comment=420270

A 18.3fps film with frames removed via a slowdown by the limo. The following insight provided: .3ft (3.74mph) per frame /.18ft(2.24mph) per frame = 1.66… / 1 ratio 1.66 - 1 = .66frames 4frames + .66 = 4.66 frames 3.5ft / 4.66 frames = .751ft per frame .751 x 18.3 = 13.744ft per sec /1.47(1mph) = 9.35mph 9.35mph x (18/18.3) = 9.2mph 9.2mph = ITEK = PAYDIRT .3 / 1.666... = .18 .66... x 1.5 =1 2.24mph / 7.47mph = .3 x (3.33…) = 1 whole frame 3.33 frames - 1frame = 2.33frames 18.3-2.33 frames = 16fps = PAYDIRT - Premature to assume that the speed reduction ratio translates as the same fps reduced ratio, at this time.

The straight line distance between Brennan and the Houston St curb is 20ft. Houston St curb line was the start of Robert West measurements at Station# 234.5. That puts Brennan at approx Station# 255.0(little radius thrown in) I would suggest obtaining extant CE884 for further distance/frame# comparisons to what Brennan described in his first day affidavit, keeping in mind that JFK within the limo was the measuring mark.

Richard, I think you nailed it. The 6th floor of the DalTex building is 10ft 10.5ft higher than the TSBD 6th floor which is 60.7ft at the window sill. Brennan said approx 75 ft high = 70ft + rifle height of someone standing up aiming. He also describes the 2nd row of windows from the top which is also the DalTex 6th floor. The frame is from the SS recreation where they are actually filming from within the car down on Elm St, giving you a LOS perspective to that window http://educationforum.ipbhost.com/topic/26636-did-even-the-warren-commission-believe-howard-brennan/?do=findComment&comment=425477

Nice view for a back shot. https://drive.google.com/file/d/1d61nVKY4YejDOnzdL1w9RJkW0ZtqkEw1/view?usp=sharing

Somewhat clearer. Add Charles Brehm and son. https://drive.google.com/file/d/1ryYq9pfyKLN7VaLc-yn-cnXVq7BmVOQ2/view?usp=sharing https://drive.google.com/file/d/1Mjs1vqNel1a-B6RKPu5yS4SSABHGdXmc/view?usp=sharing

John, I didn't say or bury anything about what Bower's could/couldn't see. That's me on the pedestal filming (inset). Fortunately at some point, my brother photographed me filming. Somewhat of a reverse perspective.

Richard, You are correct. The frame on the right I shot (one of many filming passes) while on the pedestal using a B/H 414 on normal lens setting. The bush density/height would vary throughout the years.

Paul, nicely deciphered. If interested, some additional support starting here: http://educationforum.ipbhost.com/topic/26525-unveiling-the-limo-stop/?do=findComment&comment=421212

And, complimentary to David's info: http://educationforum.ipbhost.com/topic/26646-nbc-archives-first-announcements-of-jfk-assassination/?do=findComment&comment=425369

The relevance of one shot (from behind) in relationship to the EOP. imo http://educationforum.ipbhost.com/topic/24596-shooter-location/?do=findComment&comment=369883

First announcements of the throat wound. What happened to the description of the fatal head wound/s? Whoever passed on this information apparently(by connecting it as one shot) viewed a smaller entrance hole in front and larger exit hole in back. If this was reported after the tracheotomy was performed, I would have expected the opposite(back wound smaller than the throat wound). Two separate holes conflated. https://drive.google.com/file/d/16LxwI_RjbH_1YVrHk-Tm4w_9WhKuJ0il/view?usp=sharing https://drive.google.com/file/d/16LxwI_RjbH_1YVrHk-Tm4w_9WhKuJ0il/view?usp=sharing

If CE477/8 represents where he thought he was, I'd suggest using the wall block openings as a measuring tool for the distance between the two locations with a minor radius length added in. The lamp-post at left and my red arrow would be a similar distance. Plotting Bell's LOS pretty much agrees with this photo that puts him directly across from the western edge of the first window opening in the TSBD.

Frontside and backside views stabilized.

Which one is it? He initially came alone or he was joined by Schwartz, McCormack and Sorrels. No mention of Schwartz(partner/lawyer) until after they return from Jamieson's and nothing of McCormack and Sorrels. What happens to Schwartz between the time his photo is taken(standing in the studio holding the Z camera case) while Z is interviewing on TV until they reach Kodak? Two rolls of dupe film to take to Jamieson's? Phil Chamberlain excerpts: "I don’t remember the exact time, but I think it was about 2:30 when the receptionist, Marilyn Brandon (now Marilyn Jennings), called me and said, "There’s a Mr. Zapruder here in the lobby, who thinks he might have pictures of the shooting". The lobby was on the second floor, almost next to my office, so I quickly walked out and met Mr. Zapruder. 1 He was a heavy-set man, bald on top, with an arc of black hair around the edges. He wore a dark suit, was carrying his camera bag, obviously nervous, and said "I'm not sure what I've got, but I think I was taking pictures when the shooting happened". It was much later that it sunk in that Zapruder didn't realize at the time he was taking pictures that there was a shooting. He was simply taking pictures of the motorcade, and though he heard the shots, and saw the motorcade roar off, since he was looking through the view-finder of the camera, he didn't know what had happened until he heard it on the radio — and wasn't sure what he had pictures of! But he did have a spool of 8rrm Kodachrome film, and somewhere on it, were the pictures he made of the motorcade. Dan Rather of CBS, in his book "Th'e Camera Never Blinks", states that "...we helped arrange for Eastman Kodak to process the film. This job had to be done by the best equipment. It had to be done fast. And it had to be kept confidential.". This was not so. At the time Zapruder came to Kodak, even he didn't know if he had pictures of the event, let alone Rather. Zapruder was alone, and gave every indication that he had come to the lab on his own volition, not because of urging by someone else. The Kodachrome machines had not been down long enough to require a new process check or "OK for customers’ film", and although it was very unusual for us to start up a machine for one roll of film, we soon had Zapruder's film spliced into "leader" and started into the machine, with our best processor and inspector both in the machine room. Kodachrome film took something over an hour to process, so for the next long hour, we waited, chewed our knuckles, and wondered what the film would show. Zapruder told us he had a little dress-manufacturing business in down-town. He was a very casual amateur photographer, had decided at the last minute to see the motorcade, and took his camera almost as an afterthought. When the film finally left the drying cabinet and wound up on the take-off assembly, we transferred it to a projection spool, and a group of about 15 of us — Zapruder, me, the process men, Dick Blair of our Customer Service Department, and other staff people — headed for our little conference room, where we had set up an inspection projector. We had no idea where .the pictures would be in the roll. It started off with pictures of Zapruder's family or friends, and like most amateur photographers, he sheepishly apologized for them. And then came the pictures. Fortunately, they were right-side-up, on the right-hand side of the screen. Even at the high speed, we could see the results, including the infamous frame where the top of Kennedy's head was blown off. And then nothing but blank film, where Zapruder had run off the rest of the roll to take it out of the camera. Zapruder said, "Let's look at it again", at which point I made one of my better decisions of the day. Since it is always possible that film will jump the sprocket in a projector, putting sprocket holes in the pictures — or that a piece of foreign material will lodge in the projector gate, scratching the film, I took the spool off the projector, handed it to Zapruder, told him it was now in his possession, and that there would be no charge for the processing! His next question was, "Can you make some copies?" We did not have the equipment to duplicate movies, so we called the Jamieson Film Laboratory, and asked them if they could duplicate unslit 8mm Kodachrome. They said that yes, they had the duplicating printer, but that they did not have any duplicating film perforated for 8mm. (Kodachrome film was made in three types in those days — Daylight, Type A for pictures under Tungsten light, and Duplicating Film. Duplicating film was a special finer-grain, low-contrast film, designed to give better quality copies, and was not available to the public). Our only alternative was to make the copies on Type A camera film, recognizing that they would not be of the best quality, and that Jamieson would have to guess at the color balance to use in their printer. So we gave Zapruder two rolls of Type A Kodachrome , and sent him off for Jamieson's. Less than an hour later, he was back with the two rolls of film, and a man he introduced as his partner, who was also his attorney. Once again we started a processing machine. It was now 5:30 or so. My wife had come over after work, and a little group of us sat in our smoking area-coffee shop while we waited for the processing. Zapruder was very nervous -- repeatedly mopping his brow. His suit by now was rumpled and creased. The partner was very quiet and businesslike. We all thumbed through magazines, made small talk, drank coffee, but mostly just waited. This time, we slit and spliced the films and put them on regular 8mm projection spools, and once again trooped to the conference room — this time to see the film at normal size and speed, and several times, if we wished! Those of us in the lab realized that the duplicate was soft, or fuzzy, compared to the original, but really of good quality, considering the circumstances. As we watched with a confused mixture of emotions, Zapruder commented on the film, and I particularly remember his saying, "Look, you can see where 1 jumped as I heard the shots". And sure enough, the camera jumped three times as Zapruder was startled by each shot, even though he hadn't realized at the time what they were or what was happening. We cringed when JFK's head exploded -- and guessed even then that Jackie was trying to pick up a piece of his skull or brains from the back of the convertible. Other than Zapruder's commentary, no one else talked much."

Initial viewing on the Inspection(otherwise known as an Analyst)projector. Normal 16mm speed(doubled) I equate to 2x24fps =48fps Not sure if the 4 times speed is based on a 16fps rate or a 24fps rate. Either way, 64 or 96fps possibly? Phil Chamberlain excerpt: "When the film finally left the drying cabinet and wound up on the take-off assembly, we transferred it to a projection spool, and a group of about 15 of us — Zapruder, me, the process men, Dick Blair of our Customer Service Department, and other staff people — headed for our little conference room, where we had set up an inspection projector." "Regular 8mm film (this was before the days of Super-8) was actually 16mm wide, but with twice as many perforations on the edges as the full 16mm product. Before return to the customer, it was slit down the middle, and the two halves spliced together end to end. The inspection projector was used to spot-check processed films for quality, especially for scratches or physical problems, just as quickly as they came off the machine. It ran about twice as fast as normal 16mm projection speed, and was used for both 8 and 16mm. So when 8mm. was projected before it was slit in two, there were four individual frames on the screen — with the two frames on the left side upside down! — and it ran at four times normal speed!"

Zavada excerpt: "Phil Chamberlain speculated that the perforators at the head end could have been used for the Zapruder films, the perforator "tested" between the original and dupes and because of auto indexing to the next number, 0184 was lost. Sounds good - but its speculation! We still need an example of 1963 Dallas processed 8mm movie film in a standard 50 ft. return box." There are two others besides her. I'll stick with two separate films floating around Kodak for now. Since 0184 should have been subsequent to 0183 and prior to 0185, what would make me believe that the Kodak processing session involving only the SS agent and Kenny Anderson wasn't a second(circa pedestal) assassination film perforated as 0184? Look at the LOS faint lines that were drawn on the FBI/SS plat in the previous gif.

Seems like two different films. Three people. Two films? Sounds a lot like a couple of NPIC sessions.
