Despite the criticism, PsF quickly became a de facto standard for high quality film-to-video transfer. One of the documented examples of PsF usage is the 2003 transfer of the film "[[Terminator 2: Judgment Day]]" to [[DVD]], performed by [[Artisan Entertainment]] and [[THX]]. The original 24 frame/s movie was converted to PsF format and recorded to [[D5 HD|HD-D5]] videotapes. This allowed for the creation of a [[digital master]] that was nearly identical to the original film, and made it possible to edit digitally at the native frame rate.<ref>{{cite web|url=http://www.dtvforum.info/lofiversion/index.php/t16581.html|title=Terminator 2: Extreme Edition|url-status=dead|archiveurl=https://web.archive.org/web/20080531060116/http://www.dtvforum.info/lofiversion/index.php/t16581.html|archivedate=2008-05-31}}</ref> The same digital master appears to be used for the 2006 [[Blu-ray Disc]] transfer of the movie.<ref>{{cite web |last=Bracke |first=Peter M. |date=June 27, 2006 |title=Terminator 2: Judgment Day (Blu-ray) |url=http://bluray.highdefdigest.com/terminator2.html |url-status=dead |archive-url=https://web.archive.org/web/20071018035700/https://bluray.highdefdigest.com/terminator2.html |website=Hi-Def Digest|archive-date=2007-10-18 }}</ref>

PsF has been recognized by [[Rec. 709#Frame raterates|Recommendation ITU-R&nbsp;BT.709]] as a legitimate way to transport progressive frames within an interlaced system. 25PsF and 30PsF rates have been added to the specification in addition to the more established 24PsF. "Fractional" frame rates, having the above values divided by 1.001, are also permitted; the resulting 23.976PsF and 29.97PsF rates are used in 59.94&nbsp;Hz systems. No change from 59.94 Hz systems to 60 Hz (although provided for and anticipated) has occurred allowing display on analog NTSC color televisions and monitors after down-conversion and encoding.

PsF became a means of initial image acquisition in professional Sony video cameras. It is employed in [[HDCAM]] and [[XDCAM]] video cameras, including the HDW-F900 [[CineAlta]] camera which was used by [[George Lucas]] for creating [[Star Wars: Episode II – Attack of the Clones|Star Wars, Episode 2]], and by [[Alexander Sokurov]] for creating [[Russian Ark]] fully in the digital ___domain.
