PsF has been recognized by [[Rec. 709#Frame rate|Recommendation ITU-R 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 60 Hz systems.
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
PsF is utilized in some [[DV]], [[HDV]] and [[AVCHD]] camcorders for 25-frame/s and 30-frame/s progressive-scan recording, and can be called ''Progressive recording'' (Sony), ''Progressive scan mode'' (Sony), ''Frame mode'' (Panasonic and Canon), ''Digital Cinema mode'' (Panasonic) or ''Cinema mode'' (Canon). Consumer and many professional camcorders do not use PsF to record 24-frame/s video; instead they either record it natively in progressive form or apply [[Telecine#23pulldown|2:3 pulldown]].

* '''24PsF''' (48sF, 1080sf24, 1920×1080/24/1:1SF) is the original PsF format, which is used in professional equipment for film-to-video transfer, for high definition mastering and for video exchange between networks. This may be the first universal video standard which transcends continental boundaries, an area previously reserved for film.<ref>{{cite web|url=http://www.filmmaking-careers.com/film-production.html|title=Steve Wiedemann, 24/P HDTV: The Fall of Film Production}}</ref>
* '''25PsF''' (1080sf25, 1920×1080/25/1:1SF) is used in 50 Hz systems for production that originates on video and is targeted for television distribution.
* '''29.97PsF''' (1080sf29, 1920×1080/29.97/1:1SF) formats are sometimes used in 60 Hz systems for sitcoms and music shows.<ref>{{cite web|url=http://www.avsforum.com/avs-vb/showthread.php?p=13998888#post13998888|title='Beside You in Time' by Nine Inch Nails was encoded as interlaced.}}</ref><ref>{{cite web|url=http://hometheatermag.com/discplayers/sony_bdp-s350_blu-ray_player/|title=Sony BDP-S350 Blu-ray Player review}}</ref> 29.97PsF as well as '''30PsF''' (30p, 1080sf30, 1920×1080/30/1:1SF) formats are gaining popularity as an acquisition format for Web video delivery, because most video hosting web sites cannot stream video with rates higher than 30 frame/s.
