About Offline Editing with Apple ProRes
Many of the offline editing techniques described in this chapter also apply to other video
codecs and formats. In particular, the Apple ProRes 422 (Proxy) and Apple ProRes 422 (LT)
codecs provide high-quality video for offline edits of HD and digital cinema formats. For
more information about the Apple ProRes format, see Professional Formats and Workflows,
available in Final Cut Pro Help.
Keep the following points in mind when considering the Apple ProRes format for an
offline edit:
• Offline editing with Apple ProRes is done at the original frame size, frame rate, and
aspect ratio. This is particularly advantageous for projects that involve graphics or
compositing. All versions of Apple ProRes support every popular video resolution,
including 720 x 486, 720 x 576, 960 x 720, 1280 x 720, 1280 x 1080, 1440 x 1080,
1920 x 1080, 2048 x 1024, and 2048 x 1152. This allows you to perform your offline edit
at the same resolution as your source.
• Editing with Apple ProRes at the same resolution as your source requires higher data
rates and file sizes. For example, the SD data rate of the Apple ProRes 422 (Proxy) codec
is approximately three times that of the same project in the OfflineRT format, which is
320 x 240, less than 1/4 the pixels of SD. Therefore, if data storage is the most important
issue, OfflineRT would still be the lowest data rate format for the offline edit.
Setting Up and Capturing Media to an OfflineRT Format
Before you capture, you need to choose an appropriate OfflineRT format for offline-quality
editing in Final Cut Pro.
To prepare your project for capturing media to an OfflineRT format
µ
Choose an OfflineRT Easy Setup that corresponds to the standard or your original footage
(NTSC or PAL) and frame rate.
OfflineRT Easy Setups are named with the following conventions.
• Video standard: NTSC or PAL
• Frame rate: The frame rate is included in the name of an OfflineRT Easy Setup when
nonstandard frame rates are used, such as 23.98 fps for NTSC video.
• Anamorphic: Choose an anamorphic Easy Setup if you shot your original footage with
an anamorphic lens or the anamorphic (16:9) setting selected on your camcorder.
For information about choosing an Easy Setup, see “Connecting DV Video Equipment.”
