24 frames per second (24fps)

24 frames per second is the standard frame rate or film speed for movies shot on film. It is the number of frames or images that are projected or displayed on screen per second. Before the filmmaking industry set a standard in the silent era, many films were projected at 16 or 18 frames per second, but that rate proved to be too slow when attempting to record optical film soundtracks. 24 frames per second is occasionally shortened to "24fps" or "24p."
