2:2 film detection - The ability to determine whether PAL video has been converted from film using 2:2 pulldown. Film material with 2:2 pulldown may result in artifacts and jaggies when the video signal is deinterlaced. By using 2:2 film detection to determine if the material originated from film and was converted to PAL, the video processing algorithm can be used to optimize any video for deinterlacing so that the images are free of artifacts.
