What is shutter speed?

Shutter speed is the effective length of time a camera shutter is open. The complete exposure is equal to the exposure time, or the duration of light that reaches the film or image sensor. The shutter will open at the start and then an electronic shutter simulates the function of the mechanical shutter while you are filming. When you record the video there are chances that the noise of the video will be picked up during the video recording. To avoid this and get a smooth video the important thing is to understand the relation between shutter speed and the frame rate. When you are recording video the shutter speed depends on the frame rate that you are shooting at. Most of the time will range from 24 to 25 frames per second(fps) and because of the 180-degree shutter rule, your shutter speed will be double your frame rate. The shutter speed is measured in fractions of a second. If the speed of 1/60 second means the shutter is open for about one-sixtieth of a second 1/500 is fast and 1/5000 is faster and so on and so forth.
