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 59.94 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.
