The process of removing the redundant fields from a video which was created by a telecine process with 3:2 pulldown. Inverse telecine allows MPEG encoders to recover the 24 fps progressive scan frames that comprised the original source film. For DVD content that originated as a 24 P source, the video can be encoded as 24P, which is more efficient than encoding as 30 fps interlaced video. The DVD MPEG decoder will automatically perform the 3:2 pulldown to generate 30 fps interlace video on playback.
