Line 8:
Charles Poynton, an authority in digital television, makes the following remark in his book: "Proponents of [PsF] scheme claim compatibility with interlaced processing and recording equipment, a dubious objective in my view."<ref>{{cite web|url=http://books.google.com/books?id=ra1lcAwgvq4C&pg=RA1-PA62&sig=8ZAl0RqzUYnyxQSmjxiIw4ZJDbE|title=Charles Poynton, "Digital Video and HDTV: Algorithms and Interfaces"}}</ref> He does not question the usefulness of 2:2 pulldown scheme for broadcast purposes. Poynton explains the technique used to transfer movies to video as follows: "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."
== Examples of using PsF for acquisition ==
Progressive segmented frame technology is used in [[HDCAM]] and [[XDCAM]] video cameras, including famous [[CineAlta]] camera. This camera was used by George Lucas to shoot the [[Star_Wars_Episode_II:_Attack_of_the_Clones|Star Wars, Episode 2]] movie.
== Examples of using PsF for mastering ==
=== Terminator 2: Extreme Edition ===
One of the examples of practical usage of PsF is the "Terminator 2: Extreme Edition" DVD release. Earlier releases for videotape, LaserDisk and DVD were done by transferring the original theatrical release to 60i video using 2:3 pulldown scheme, then by editing the resulting video. The final result was interlaced video with 2:3 cadence being constantly interrupted. The broken cadence made no difference for analog television, but became a problem when progressive scan TV sets with 2:3 cadence detection became commonplace.
Considering tremendous popularity of the "Terminator 2", Artisan and THX performed a completely fresh transfer of the movie to digital form in 2003. They started with creating a new high definition digital master by converting original 24fps film to 1080PsF24 format and recording it to HD-D5 videotapes. Usage of progressive segmented frame allowed creating a digital master that is identical to original film, and made possible to perform all digital editing in 24p mode.<ref>{{cite web|url=http://www.dtvforum.info/lofiversion/index.php/t16581.html|title=Terminator 2: making of}}</ref> It is also worth nothing that this digital master appears to be used for 2006 Blu-Ray transfer of the movie.<ref>{{cite web|url=http://bluray.highdefdigest.com/terminator2.html|title=Terminator 2: Judgment Day (Blu-ray)}}</ref>
