Apple Final Cut Pro 7 - Manual (Page 1936)

2:3:3:2 Advanced Pull-Down
Camcorders such as the Panasonic AG-DVX100, the Panasonic AG-HVX200, and the Canon
XL2 use this method to store 23.98 fps video within interlaced 29.97 fps footage. Video
frames 1, 2, 4, and 5 in the pull-down pattern represent film frames A, B, C, and D.
Removing advanced pull-down is more efficient than removing standard 2:3:2:3 pull-down
because no deinterlacing is required. To remove advanced pull-down, video frame 3 in
the five-frame pattern is simply discarded during capture or ignored during playback.
