An Ercoupe pilot shows in this video that he can nearly eliminate the annoying prop blur with just a Neutral Density filter over the lens of his camera. How does that work?

It is caused by a rolling shutter (think the way your TV scans the image). The pixels in the CMOS sensor are recorded the same way. One sure fire way to eliminate it is to record only with CCD based video cameras that use a global shutter (all at once).
There are drawbacks and positives for both types.
