24 @ 25 Repeat
This method simply repeats every 24th frame once to fit 24 fps footage into 25 fps. This
causes a noticeable stutter every second but requires less processing than the 24 @ 25
pull-down pattern because no special interlacing is required. This pull-down pattern is
analogous to the NTSC 2:2:2:4 pull-down pattern in the sense that it requires the least
amount of processing power but results in the most noticeable stutter. You should use
this option for preview purposes only and avoid it for final output.
Native 24p
Some video camcorders that record to file-based media can record at 24 or 23.98 fps.
For example, the Panasonic AG-HVX200 can record 23.98 fps footage directly. Digital
cinema cameras such as the Panavision Genesis, the Dalsa Origin, and the RED-ONE can
record natively at 24 fps. Of course, film is also recorded at 24 fps.
Film, 24p Video, and Cinema Tools
Cinema Tools is used mainly to edit movies shot and finished on film, or whenever film
production techniques such as separate picture and sound recording are used. To make
editing cheaper and more convenient, NTSC or PAL telecine transfers are used as
intermediate digital editing formats. Cinema Tools can remove 3:2 pull-down from
29.97 fps telecined video or conform 25 fps telecined video back to 24 fps so you can
edit at the proper frame rate. For more information, see Chapter 12, “
