International standard for motion picture film shooting and projection, though film shot for television in 625 scanningline countries is usually shot at 25 frames per second (even if not, it is transferred to television at 25 frames per second). There are moves afoot in the U.S. to increase the film frame rate to 30 for improved temporal resolution.

The ImageVision HDEP system and other electronic cinematography systems use 24 frames per second. RCA once proposed an electronic cinematography system with 2625 scanning lines (2475 active), a 2:33:1 aspect ratio, and a frame rate of 23.976023 frames/sec.
