Line 11: PsF technology is implemented in [[HDCAM]] and [[XDCAM]] video cameras, including famous [[CineAlta]] camera that was used by George Lucas for the [[Star_Wars_Episode_II:_Attack_of_the_Clones\|Star Wars, Episode 2]] movie. == PsF vs. 2:2 pulldown ~~used in PAL/SECAM systems~~ == Progressive segmented frame technique is equivalent to [[Telecine\|2:2 pulldown]] pattern, which is widely used in PAL/SECAM television ~~for at least half a century~~. As Charles Poynton explains, "film is transferred to 576i video using 2:2 pulldown: Each film frame is scanned into two video fields (or frames); the film is run 4% fast." It seems that "PsF" is used for material originated on video, while "2:2 pulldown" is used for [[Telecine\|telecine]] process, and in broadcast. Poynton does not question the usefulness of 2:2 pulldown scheme for broadcast purposes. == 24PsF ==
