"Raw Footage #1: The F.M. Bell film out-of-camera original" by - The JFK Theorist (1:19)
The Bell Film still frame you have posted above is CROPPED. Zapruder is visible on the (L), on an Uncropped Bell Film. Sitzman is also visible between the sprocket holes.
I recommend you use the Bell Film I have listed above to help with your time stamping. "The JFK Theorist" posts extremely good copies of JFK assassination films on You Tube. He sometimes posts on this forum as "Alex Harris".
Altgens gave WC Testimony that he initially followed law enforcement UP the knoll. When we see Altgens above, he has come back down the knoll and is now walking laterally L-R. Tick Tock, Tick Tock.
Firstly, this version of Bell is FAR superior to the one I was using and will be far more helpful, so thanks for that.
I'd like to go slowly to piece together my thinking here. The first thing I'd like to clear up is your comment in an earlier post that in the Bell film Weigman can be seen walking towards Zapruder. As far as I can tell this is not correct but I might be misunderstanding something so I'd like to clear it up. It's not a 'gotcha' or anything, just a genuine attempt to work this timeline out.
In the Bell film we see the limo enter the underpass followed by 3 cars. The camera then quickly pans to the right and shows us the GK area, where we see Zapruder and Sitzman making their way from the plinth and, as it pans across, Weigman in a prone position from where he was filming the Hesters:

This is the moment just before there is a cut/jump in the film.
We can see Weigman lying on the steps. He has just finished filming the Hesters (Mr Hester can be just about made out in the shadows of the pergola, Mrs Hester is getting up from her prone position). Weigman turns around and starts to get up. In the bottom left corner we can see Hargis stood by the lamp post.
The film then cuts/jumps to the scene below. There is no way to tell how much time has passed but a few things have changed - Altgens has appeared out of nowhere, Weigman is now filming the Newmans and Hargis is now running across the road:

Do you agree that the Bell film does NOT show Wegman walking towards Zapruder?
Do you agree there is no way to tell, just by watching the Bell film, how much time has passed between these two images because of the cut/jump?
Do you agree that Weigman has moved from his position filming the Hesters to his position filming the Newmans?
Again, no 'gotchas', just honest questions.
