E1. Choosing between shutter speed or shutter angle
The shutter speed or shutter angle effects how motion is
portrayed in the recordings. A very fast shutter will freeze
rapid movements in each frame of the recording making
them crisper but possibly adding judder or jitter. Too slow
a shutter speed will result in blurred motion and handheld
camera wobble can result in soft looking pictures. In
addition, a fast shutter speed reduces the amount of
captured by the sensor.
The camera can display the shutter time period as either
fractions of a second (shutter speed) or in degrees. In
either case the operation of the shutter is identical, there is
no difference in the quality of the images captured.
Shutter speed is the easiest to understand and is similar
to how the shutter period would be expressed in a stills
camera. With Shutter Speed the shutter timing remains
fixed at the speed set even if you change the recording
frame rate (unless the shooting frame rate is increased
beyond the set shutter speed, in which case the shutter
speed will become set to the slowest possible speed for
the shooting rate chosen).
The Shutter Angle setting mimics the way the shutter
period of a movie film camera would be expressed. The
shutter in a film camera is a spinning circular disc, part
