 | | Originally moving picture film was shot at various speeds using hand-cranked cameras; then the speed for mechanized cameras and projectors was standardized at 16 frames per second, which was faster than much existing hand-cranked footage. |
 | | Improvements since the late 1800s include the mechanization of cameras, allowing them to record at a consistent speed, the invention of more sophisticated filmstocks and lenses, allowing directors to film in increasingly dim conditions, and the development of synch sound, allowing sound to be recorded at exactly the same speed as its corresponding video. |
 | | Since the advent of many other media technologies, film may include a broad range of media — both linear and non-linear, dramatic and informational, motion and still (though progressive). |
