Recording movies

two aspects of movie recording that are easily confused are frame rate and shutter speed. But while the frame rate sets the recording speed, the shutter speed determines how long each frame is exposed to light. Fast shutter speeds can make moving objects appear well defined but ‘jittery’, while slow shutter speeds can produce smoother motion, at the risk of moving subjects appearing blurred. The best compromise is to set a shutter speed that’s double the frame rate – so 1/60 sec for a frame rate of 30fps.
