The motion blur is meant to be the movement that occured whilst the camera
shutter was open for that frame, so it needs to uses images from periods of time
in-between frames, not overlapping with other ones. So the first frame needs
multiple samples of the motion that occured in the first 1/30th of a second, the
second needs the next 1/30th of a second. I chose to take 10 samples of the
movement over the course of a frame, hence I need to render 10 times more
frames.

If I overlap it I get a 1980's video ghosting-trails special effect, not motion
blur :)
