2:3

A pull-down (conversion from film to video) method that involves a 2:3 ratio of film frames to video frames, after the film has been slowed down 1/1000 to 23.976 fps to correspond to the 29.97 fps drop-frame video playback used for interlaced television transmission in the United States. Two steps are involved: slow down the film motion by 1/1000 to 23.976 (for a two-hour film, play time is only extended by 7.2 seconds) and then distribute film frames into video fields (23.976/29.97 = 4/5 or four film frames of film for every five frames of 60 Hz (59.94 fields) per second video. These four frames are "stretched" into five by exploiting the interlaced nature of 60 Hz video.
