2:2

A pull-down (conversion from film to video) method that involves a 1:1 ratio, often used for conversion of 25 frames per second (fps) from film to PAL or SECAM video standards. In other words, for every film frame, one video frame is captured. Sometimes also used as a 24 fps film to 25 fps video conversion (at a 4% increase in speed) with an accompanying pitch shift to hide the noticeable audio pitch differential. Another option is the 2:2:2:2:2:2:2:2:2:2:2:3 pull-down in which inserting a single frame pull-down field is used every 12 film frames or every 12.5 frames of PAL video (12 frames of film for every 25 fields of PAL video).
