As far as I am aware the realy high speed cameras get around this problem by
not moving the film. Instead the optics (or part of them) are rotated fast.
So you would have a casing with the film layered along the furthest edge
(semi cylindrical). A rotating mirror is then used project the image along
I've seen a picture of a similar camera that was used to plot the progress
of high explosive shockwaves.
