Chapter 11 Working With 24P Video and 24 fps EDLs 185
Using the Reverse Telecine and Conform Features
24P video is often downconverted to make it easier to use with standard video
equipment. Cinema Tools provides tools to convert NTSC or PAL captured clips back to
their original 24 fps video, enabling you to edit using a 24 fps timebase.
 NTSC: Converting 24P video to NTSC requires using a pull-down method that adds
redundant fields, maintaining the action’s original speed (one second of 24P video
equals one second of NTSC video). The Reverse Telecine feature removes the pull-
down by removing the extra fields and restores the original 24 fps rate. See
“
Reversing the Telecine Pull-Down ” on page 113 for information on using the Reverse
Telecine feature. If your source clips originated from a special type of DV camcorder
that shoots 24P, such as the Panasonic AG-DVX100 camcorder, a simpler form of the
Reverse Telecine dialog appears. See “
Removing 2:3:3:2 or 2:3:2:3 Pull-Down With
Cinema Tools ” on page 190 for instructions on reversing the pull-down for clips that
originated from a 24P-capable digital video camcorder.
 PAL: There are several methods of converting 24P video to PAL. The most common is
to play the tape four percent faster, providing a one-to-one relationship between the
24P and PAL frames, but speeding up the action by four percent. Cinema Tools
provides a Conform feature that you can use to restore the video back to 24 fps in
order to edit it at 24 fps in Final Cut Pro. See “
Frame Rate Basics ” on page 22 for
information on frame rate issues.
Exporting 24 fps EDLs
Whenever the 24P online editor is not Final Cut Pro, the best way to provide it with the
project’s edit information is to export an EDL from Final Cut Pro, which you can then
import into the online editor. EDLs contain only the basic information about an editing
project: the In and Out edit points for the first two video tracks and the first four audio
tracks, information for simple transitions, and any notes you have added. Cinema Tools
provides Final Cut Pro with the ability to export 24 fps EDLs.
To export a 24 fps EDL from Final Cut Pro:
1 Select the sequence you want to export an EDL from in the Final Cut Pro Timeline.
2 Choose File > Export > EDL.
3 Configure the EDL Export Options dialog as required, then click OK.
4 Choose the name and location for the EDL file, then click Save.
See the Final Cut Pro documentation for details on exporting EDLs and configuring the
EDL Export Options dialog.
