Anyone can correct me if I’m wrong, but I was always under the impression that the difference between 24p and 24pA was the cameras method of adding pull-down so that the 24fps will fill the 29.97fps of tape.
Removing advanced pulldown from the 24pA footage can be done in Final Cut, but I believe standard pull-down must be removed in Cinema Tools when working with 24p
