Hello Andrew,
I hope you will explain something about the film to NTSC video transfer
process. You are in conflict with my way of thinking and am getting
confused.
You say it uses a 3:2 pull down which puts one frame of film on 3 fields
of NTSC video. Since the system uses 2 interlaced fields per frame
(interlaced scanning) this puts two film frames in one video frame, every
other frame. The result would be one film frame being scanned by the even
lines (first field) and the NEXT film frame being scanned by the odd
lines (second field) in a single video frame. Somehow that makes no sense
to me.
Whatever way they do it however, they almost completely eliminate that
annouing flicker in the cinema and my eyes defocusing every time the
camera pans, hi.
