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 iswas 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>
