'''Motion interpolation''' is a form of [[judder|de-judder]] [[video processing]] used in various display devices such as [[HDTV]]s and video players. New [[Film frame|frames]] are [[interpolated]] and inserted between standard frames to smooth the picture. [[Films]] are recorded at a [[frame rate]] of 24 frames per second (frame/s) and television is typically filmed at 25, 50, 30 or 60 frames per second (the first two being PAL, the other two from NTSC). Display devices such as HDTVs may have a [[refresh rate]] of 60, 100, 120 or even 200<ref>{{cite web |url=http://www.pcauthority.com.au/News/123515,sony-pumps-motionflow-200hz-with-new-bravia-z-series.aspx |title=Sony new 200hz motionflow technology |accessdate=2008-10-19}}</ref> [[Hz]]. The display device can repeat the standard frames or insert new frames that are interpolated on the fly.
