Bill, Yes, some believe it is Oswald and others don't, based on different criteria.

Yes, I would agree with that.

This is one of the advantages of using stabilized video, as opposed to still frames or photos, if the same time period is covered. The reason I use "lean forward" and not "moving" is, at this point, Lovelady is not on the top landing. I believe those steps don't have enough depth for someone to move forward, if they did, one would be stepping down or up and we would see it in the video. I don't see Lovelady's elevation change in the video compared to the African-American fellow below him. Imo

Yes, Lovelady. The video I provided is from Hughes. The limo is turning the corner from Houston to Elm at that time, same as your single frame. This occurs many seconds before Altgen's 6.

Excellent Research Bart. I inverted a few of the photos. https://drive.google.com/file/d/0BwrExtVD005OZWdJNE5MWTVFeUk/view?usp=sharing https://drive.google.com/file/d/0BwrExtVD005OdUN6WF9PSXpZMWc/view?usp=sharing https://drive.google.com/file/d/0BwrExtVD005Oc0Fmcnoxbjg5a2M/view?usp=sharing

In Hughes: He leans forward, out of the shadows and then back. https://drive.google.com/file/d/0BwrExtVD005OemhFSmFyNlR0cEE/view?usp=sharing

Pennsylvania article date: Oct 13, 2016-see previous graphic Excerpt from Rove article (July 7, 2016): Even where the GOP has been successful in registration, maximizing Republican turnout is not enough to flip states. Take Pennsylvania, where GOP increases and Democratic declines have combined to produce a 216,916 shift toward Republicans since 2012. But Mr. Obama won the state by 309,840: Mr. Trump would need to convince 100,000 more Pennsylvania independents and Democrats to back him while carrying all the voters Mr. Romney won and the newly registered Republicans. http://www.rove.com/article/the-off-stage-battle-to-sign-up-voters

https://drive.google.com/file/d/0BwrExtVD005OSnpNZlNjbnpYWXc/view?usp=sharing The original is from the DVD “Death In Dealy Plaza” I copied the VOB files directly from the DVD. Computer = Mac I viewed the VOB files using this program “MPEG Streamclip” - QuickTime Pro works just as well, with both programs needing “QuickTimeMPEG2.component” for the viewing process. I snapshot the frame as a PNG. I can also export as PNG’s but not at 200% which is the size of the linked file. The screenshot was captured using a gamma of 1.8 The frame is not cropped my me. This is what is supplied on the DVD. There is no difference in quality (Mac wise) between a snapshot PNG and an exported PNG. (Believe me, I’ve tested this numerous times). I believe the current frame/s being discussed on the forum were snapshot at 100%. The photoshop process for this frame would have been the same as the others, although I believe I also used a "Topaz Labs plugin" contrast filter to try and bring out more detail in the shadows. There are dozens to choose from. Bart Kamp did a good job in his collage trying to match whatever I had previously produced. He marked it "Hairline and Ear". Maybe he remembers his exact method for contrast adjustments, I don't. As far as I could find, this was the closest I could get (generation wise) to some type of documented version. What generation is it? I don't know. The 16mm Wiegman film, more than likely, was supplied by the 6th Floor Museum for the T.V. show. The rest is up to those still interested. Good Luck, chris

This will be the last equation (which includes the streamlined explanation below). I wish everyone continued success in whatever endeavors they may pursue. The ratio of 16FPS - 18.3FPS = .874 The ratio of 2.622(48/18.3)- 3 = .874 cheers, Chris Davidson

The adjustment at z168-z171 reveals the 1/4 difference between 18fps and stepped down 24fps. z168-z171 = 3.734mph z168-z186 = 18frames x 1.016 = 18.3fps @ 21.6ft x 1.016 = 21.96ft per sec / 1.47 (1mph) 14.938mph 3.734mph / 14.938mph = .25 Difference between 18 and 24fps = 6fps 6fps/24fps =.25 P.S. Here's a simple question for you. How many frames do you expel to end up with a 1/4 ratio? Added on edit below:

z173-z232 = 59frames Reconstruction = frame 181-236 = 55 frames 59 Impala is 3.77ft shorter than the limo. 3.77ft made up in terms of average speed throughout this span = 3.57 frames = 4 whole frames. 55 + 4 =59 fames = Reconstruction total The cars front and rear ends in relation to the Stemmons sign are the markers. 59frames to cover the same distance in each film. 59/24fps = 2.458sec 62.35ft / 2.458 = 25.36 ft per sec = 17.25mph The recreation film is shot at 24fps. The extant zfilm is a stepped down frame version.

Before I post the landmark frame comparison, here's my question to non-alterationist believers: If two vehicles travel the same distance in the same amount of film frames, is the frame rate in both cameras the same? I'll give them a little while to ponder that.

The distance per frame for the 17.25mph average is: 17.25 x 1.47 = 25.35ft per sec / 24 frames = 1.056 ft per frame The 1959 Impala is 3.77ft shorter than the limo so any comparison between the two in terms of landmarks has to be considered. 3.77ft / 1.056ft per frame = 3.57 frames or 4 whole frames added.

Since I have the landmark frame comparison completed and ready to post, I'll do the R X T = D formula first. I chose z173- z232 for a total of 59 frames partly because we can get feedback on the WC specs from CE884 final plat version of May 1964. Their span from z171-z231= 60 frames @ 63.4ft traveled A 24fps movie using these numbers will get you this: 60/24 = 2.5seconds 63.4ft/2.5sec = 25.36ft per sec = 17.25mph 59 frames using that average would equal the same 17.25mph That would be quite a consistent speed with the overlay comparison movie between the lexus and limo. Added on edit below:

Now, all one has to do is apply a rate x time = distance equation and/or a frame count comparison between the two films using common Dealy Plaza landmarks in relation to the same part of the vehicles. Here's a hint at this time. That is a 1959 Chevy Impala Sport Coupe. It is 210.9" long = 17.57ft. The difference in length between the two vehicles is 3.77ft

for those uninitiated, the why's of 29.97fps is explained here... https://documentation.apple.com/en/finalcutpro/usermanual/index.html#chapter=D%26section=6%26tasks=true for those uninitiated, the why's of 29.97fps is explained here... https://documentation.apple.com/en/finalcutpro/usermanual/index.html#chapter=D%26section=6%26tasks=true David, More math, you know how much I hate that subject.

I then took the liberty of removing all but the progressive frames from the SS reconstruction video so now we're only dealing with whole frames. You might remember this: https://drive.google.com/file/d/0BwrExtVD005OUmxsRlJLSGhwNE0/view?usp=sharing

It seemed a stretch to believe that Underwood or an associate would have filmed the SS recreation at 18fps since the camera he normally used was most likely a "Bell and Howell Filmo" standard 16mm/24fps camera. The pulldown frames conversion answered that question. Reconstruction shot at 24fps.

The version of the SS recreation film which includes the pulldown footage is here:

I created a gif showing the end result of reverse telecining which shows the conversion of the 3/2 pulldown or 5 frames back to its original 4 progressive. The top part of the gif is the 3/2 pulldown process from the original. The middle part is the reverse telecine result converting it back to its original four progressive frames. Added on edit: I would suggest downloading this and playing it at full view so the pulldown frames are quite obvious to see. https://drive.google.com/file/d/0BwrExtVD005OTjgyVDJSTXlnZUE/view?usp=sharing

There was a suggestion that the SS recreation video was shot at approx 18/18.3fps. If that was indeed true, the pulldown conversion ratio would have been different. 29.97/18 = 1.665/1 ratio = 5/3 pulldown ratio.
