Life Magazine damaged their copy of the film which is probably the original source of of the two clips you posted. But the original Zapruder in camera version has been transferred and that's why we don't see the big jump as in your version and the unedited Zapruder film is what seen in Anthony's video.

And the FBI accidentally damaged a photo of a man in the 6th floor window and the original Nix film was lost as was Mary Moorman's photo of the TSBD, taken just before the first shot, and, for some unknown reason the FBI "lost" the original Klein's' microfilm. It's all a coincidence, I'm sure....
