Rich DellaRosa talks about the Other Zapruder film.

[Greg Burnham]

I doubt it. IMO it is an unedited version of the Z film. What it shows would make clear what has been excised and why.

Didn't you mean to say: "In my grossly uninformed opinion it is an unedited version of the Z-film?"-- How can you have an informed opinion about
what something actually is if you haven't even seen it?

I've read and listened to accounts of the other film. They are not detailed enough IMO, to be evidence of a different film. There is no evidence of another camera in the same or similar psoition to Zapruder. Of course there could be and perhaps there is indeed another film, but a simpler explaination would be an unedited Z film. The people who have seen this describe three main differences. The car is seen turning on Elm, the car is seen comimng to a complete stop, and the two head shots seem separated. If these frames are rmoved you have essentially the Z film. As someone who has seen the other film, do you recall how it was framed at the momet of the head shots? How much of the car was in frame when you observed the full stop? I don't recall in your account, you being adamant that it was a different film.

I am not adamant, however, there are some differences that do seem to negate the possibility that it was the same unedited version of the film. For instance, in the extant Z-film the limo is framed extremely low in the view finder. In the film I saw the limo was not framed that way.
