How much could you alter the film if Abraham Zapruder had shot in slow motion mode?

[David Josephs]

Thanks Chris - I'll see what I can do with it.

I did some quick removal work and it's amazing really.

The more I do the more it looks like the Zfilm as the limo moves down Elm you can see the mini jumps as Zap moves the camera around... same as what I just did.

Gotta run now but will post the work and analysis soon

Thanks again Chris

David,

The zfilm shot at 48fps and viewed at 15fps would have looked something like this.

Sorry I didn't make it to the films end, but, you get the idea.

Couldn't fully support a 48fps scenario until I figured out the math between CE884's and applied it to the extant zfilm. Just the way I approached it.

Kudos to you and Doug Horne for sticking with it.

That's fascinating. Costella found something odd with the sign when he did his pincushion correction, and in that version - to me - the sign jumps around. Also for some reason it seems like the "blob" after the head shot looks more like a massive wound - again to me - it looks like the entire front right side of his head is gone. Anyone else see that? Does it look dramatically different to anyone else or are these old eyes f'ing with me?

Thanks Chris - the 15fps play speed makes the movie look slower than would normally be if played at 18fps - correct?

The other thing is that the final ratio of total starting frames to total ending frames needs to be 18.3

48fps / 18.3 fps = 2.623
486 frames x 2.623 = 1275 total frames if it was all filmed at 48fps.

In your motorcycle example, take the total frames and divide by 2.623 to get the ending # of frames required.

136 frames / 2.623 = 52 frames which means we need to cut 84 frames and show at 18fps on a projector.

Just look how jumpy this is even though it is stabilized. the jerkiness of the forward motion of the limo is exactly what we see when removing frames from the motorcycle scene
When the limo slows just before 313 it also smooth and then just after, it looks like a number of frames are gone - there is a jump in the film and the impossibly fast movements of Greer and Kellerman.




I removed the 2nd and 3rd frame from each 3 frame pair thru the turn then it goes back to no frames missing at 48fps shown at 18fps.
