A camera with a shutter like that does not exist. If it has a 45 degree
shutter-angle, that means the frame is still held for 1/24th of a second,
however exposed 1/4th of the time. This results in an image with less
motion-blur and this can look jerky. See "Saving Private Ryan", where
Janusz Kamynszki used a 30 degrees shutter-angle on the opening bit.
