Editing Video (section)

===Number of frames per second===
''[[Frame rate]]'', the number of still pictures per unit of time of video, ranges from six or eight frames per second (''frame/s'') for old mechanical cameras to 120 or more for new professional cameras. [[PAL]] standards (Europe, Asia, Australia, etc.) and [[SECAM]] (France, Russia, parts of Africa, etc.) specify 25 frame/s, while [[NTSC]] standards (United States, Canada, Japan, etc.) specify 29.97 frame/s.<ref>{{cite web|last1=Soseman|first1=Ned|title=What's the difference between 59.94fps and 60fps?|url=http://www.tvtechnology.com/media-systems/0191/whats-the-difference-between-fps-and-fps/241737|access-date=July 12, 2017|url-status=dead|archive-url=https://web.archive.org/web/20170629190309/http://www.tvtechnology.com/media-systems/0191/whats-the-difference-between-fps-and-fps/241737|archive-date=June 29, 2017}}</ref> Film is shot at a slower frame rate of 24 frames per second, which slightly complicates the process of transferring a cinematic motion picture to video. The minimum frame rate to achieve a comfortable illusion of a [[Persistence of vision|moving image]] is about sixteen frames per second.<ref>{{cite news | url=http://vision.arc.nasa.gov/publications/TemporalSensitivity.pdf | title=Temporal Sensitivity | first=Andrew B. | last=Watson | year=1986 | journal=Sensory Processes and Perception | url-status=dead | archive-url=https://web.archive.org/web/20160308001647/http://vision.arc.nasa.gov/publications/TemporalSensitivity.pdf | archive-date=March 8, 2016 }}</ref>
