Shutter speed determines the amount of time that the camera shutter is open for and how long the sensor is exposed to light. Having the shutter open for a longer amount of time means you're recording light for a longer period of time, and so you get motion blur in your images. If you want to freeze action, you would shoot on a fast shutter speed so you're only capturing a small period of light. In moving image, shutter speed does the same thing and different shutter speeds paired with certain frame rates give different results. In moving image, the shutter speed determines how long each frame in the video is exposed for. In the examples above, you can see that the slowest shutter speed (1/30th) produces a blurred still, and the video as a result looks quite smooth and blurred throughout. In the opposite extreme, the video with the short shutter speed (1/100th), has very clear lines and images which makes it seem quite frantic and non fluid. This could have practical applications, such as showing somebody as being in a panicked state.
