PsF is utilized in some [[DV]], [[HDV]] and [[AVCHD]] [[camcorder]]s for 25-frame/s and 30-frame/s progressive-scan recording. To achieve this, the camera acquires 30 ([[NTSC]]) or 25 ([[PAL]]) independent images per second. These images are output as 60 (NTSC) or 50 (PAL) interlaced fields. The result is a progressive-scan
This is how Sony described the progressive recording mode in the operating guide for a 60 Hz ("NTSC") Sony DCR-HC96 camcorder:

}}</ref> Such a reduction improves compression of the video signal, which is always desirable because of storage and transmission limitations. To ensure compatibility with interlaced-based systems, chroma information in PsF video is sometimes recorded in interlaced format, despite that the content is progressive. This may result in interlaced artifacts being noticeable on colored objects.<ref>
