There is no reason why shortened shutter speeds can't also be used at
lower frame rates, however. If you want to capture fast motion with
little blur, you can use 1/1000 shutter speed, then transmit at 60 fps.
In principle.


This doesn't work at lower frame rates as you might think. The blur is
needed to create the impression in the mind that the image is in motion.

Eliminate the blur by using a fast shutter, and you cause great
discontinuity in motion. The moving image breaks up into a series of fast moving stills.
Watch the news for a shot of a helicopter's blades spinniing. If you can clearly see the individual blades, it's because the camera is operating with a fast shutter setting, more than 1/60th of a second.
