what is frame rate

Frame rate is the frequency at which consecutive images or frames are captured or displayed, typically expressed in frames per second (FPS) . It is the speed at which images are shown, or how fast you “flip” through the book. The higher the frame rate, the more refined the movement in a video, and a higher frame rate is generally better than a lower rate. Frame rate is used in film and video cameras, computer animation, and motion capture systems, and may be used interchangeably with frame frequency and refresh rate, which are expressed in hertz. In the context of computer graphics performance, FPS is the rate at which a system, particularly a GPU, is able to generate frames, and refresh rate is the frequency at which a display shows completed frames. The most common frame rates are 24fps for cinema, whereas 30fps and 60fps are used for television and online content. Different projects and mediums may require different frame rates, and there is controversy around which rates provide the best viewing experience.
