Working with 24p Sources
With the emergence of 24p HD video recorders, there is a growing need for Final Cut Pro
to support several aspects of editing at 24 fps (in some cases, actually 23.98 fps). To this
end, Final Cut Pro and Cinema Tools provide the following:
• The import and export of 24 fps and 23.98 fps EDLs
• The ability to convert NTSC 29.97 fps EDLs to 23.98 fps or 24 fps EDLs
• A Reverse Telecine feature to undo the 3:2 pull-down used when 24 fps film or video
is converted to NTSC’s 29.97 fps
• The ability to remove 2:3:3:2 or 2:3:2:3 pull-down from NTSC media files so you can edit
at 24 fps or 23.98 fps
• The ability to output 23.98 fps video via FireWire at the NTSC standard of 29.97 fps
video
• The ability to match the edits of videotape audio with the original production audio
tapes and generate an audio EDL that can then be used to recapture and finish the
audio if you intend to recapture it elsewhere for final processing
Several of the features mentioned above are included with Final Cut Pro and do not
require Cinema Tools; however, this manual describes all of these features because they
relate to working with 24p, which is of specific interest to many filmmakers. See
Frame
Rate Basics for more information about working with the different frame rates.
Offline and Online Editing
If you are working with a high-resolution 24p format, such as uncompressed HD video,
you may need to make lower-resolution copies of your footage to maximize your
computer’s disk space and processing power. In this case, there are four basic steps to
the editing process:
• Production (generating the master video): Transfer film to or natively shoot on
uncompressed 24p HD video.
• Offline edit: Convert footage to NTSC or PAL video (which is generally lower-resolution
than 24p) and edit it.
• Project interchange: Export a Final Cut Pro project or an EDL containing your final edit
decisions.
