Chapter 11 Working With 24P Video and 24 fps EDLs 183
Using Final Cut Pro as a 24P Offline Editor
Editing 24P HD video generally requires that you first edit it with an offline system. This
allows you to choose the actual footage you want to use while working with
downconverted or compressed versions of the 24P video.
When the online system also uses Final Cut Pro, it is highly recommended that you
perform an offline edit using a 24 fps timebase. This allows you to open the project
with the online system and maintain all special settings, effects, and filters—things that
are not included in an EDL.
With online systems other than Final Cut Pro, you need to provide a 24 fps EDL from
the project.
Cinema Tools provides several tools that make it easier to use Final Cut Pro for 24P
offline editing:
 Reverse Telecine and Conform features: Useful when you have captured
downconverted versions of the 24P video and want to convert them to back to
24 fps
 24 fps EDL export: Useful when you edit with a 24 fps timebase and require a 24 fps
EDL for the online system
 NTSC-to-24 fps EDL conversion: Useful when you must edit using an NTSC 30 fps
timebase but need a 24 fps EDL
For offline editing, it is preferred that the 24P video be compressed and captured
directly, with no frame rate conversions. This removes the possibility of errors during
video and timecode rate conversions, and eliminates the need to convert the video’s
aspect ratio. However, this requires specialized hardware, so the following alternatives
using standard downconverted versions of the 24P video have been developed.
