Working with 24p Video

If you edit 3:2 pull-down footage without removing the pull-down first, you need to be
particularly careful to match the five-frame pull-down cadence at every edit. Edits with
broken cadence, such as a repeating or out-of-order frame (for example, A, B, A, B, C, D)
can confuse reverse telecine operations. In general, you should avoid editing 29.97 fps
pull-down footage. Instead, remove the pull-down of your footage first, edit at
23.98 fps, then reinsert pull-down during output.
Several NTSC and 1080i60 HD camcorders can record using standard pull-down,
though advanced pull-down is usually recommended when recording 24p video.
However, for final playback on television or DVD, 3:2 pull-down is generally considered
to have the most acceptable quality of motion.
