Ever wonder why pictures / video taken with modern cameras distorts a moving propeller. 

 

Here’s a moving illustration showing why.

As opposed to a film camera, which captures the entire image at the same time, electronic cameras scan the image from top to bottom, or vice-versa.  Since the prop is moving, it appears in different positions as the scan progresses.
