TECHNICAL DESCRIPTION
The field dominance for 30 FPS NTSC and 25 FPS PAL transfers is
assumed to be field 1.
beginning of field 1 of a video frame.
The pulldown for 24 FPS NTSC transfers will be random. As there is
usually no real pulldown of the picture, but rather a blending of pictures as
they change mid-frame, this method will track the film frames to within 1
frame of accuracy.
