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

[Chris Bennett]

The film clip appears normal to me. The question is, by this method, how much could you hide? Surely somewhat less than 1/17 of a second's worth of information, which missing bits we could clearly infer by what is left, like the sudden slowing of the cycle as it makes the turn, or the fact that the rider almost plants a foot on the ground.

That's a good point.

Even with a frame or two, it seems like you could eliminate clear evidence of a shot. Or in the case of Z313, what happened around a shot. Brugioni was clear that in the version he reviewed, the head explosive was definitely more than one frame.
