So what is Shutter Speed?
Shutter Speed is the set time for which a shutter is open at a given setting of a mode. This is how it works, When the camera shoots a photo, or whilst shooting a video, the shutter opens and fully exposes the camera sensor. Light passes through the lens aperture (the F stop). After the sensor is done receiving the light, the shutter closes immediately (how fast depends on your shutter speed which can be changed in the settings on your camera). After stopping the light from hitting the sensor the button that fires the camera also called the 'shutter button' because it triggers the shutter to open and close. Or to start and stop recording.
here is a video of what the shutter does. In slow motion.
With a slower shutter speed in video you can end up a really blurry / stuttered image. Although this can create an original effect to the film footage. This can be used as flash backs in films, such as in the 'Jason Bourne films' the image is normally hard to understand depending on the shutter speed. A slow shutter speed is used for these type of shots.
However, with a higher shutter speed the video mostly looks crisp and clear with plenty of detail. The frame rates are normally high also with results in silky smooth film, which can look professional if shot in the correct resolution (1080p+).
