Apple Final Cut Pro 7 - Manual (Page 1835)

In some cases, a clip’s Creator property determines what application will open it, such as
Motion clips. However, for generic media types such as audio and video, you can assign
any application you want. For example, you could set Peak DV as your audio file editor
so you could quickly make permanent changes directly to the source audio files on disk
(such as using a noise reduction filter available in that application to clean up a particularly
noisy clip). In this way you could apply effects or special sound-sweetening filters before
continuing work on your edit.
Note: If <None Set> appears next to an entry in the list, that type of clip is opened in the
same application that would open if you double-clicked the corresponding media file in
the Finder. To override the Finder default, you must specify an application to open for
each type of media clip.
To set an external editor
1 Choose Final Cut Pro > System Settings, then click the External Editors tab.
2 Click Set next to the clip type for which you want to assign an external editor.
3 In the Open dialog that appears, navigate to the location of the application you want to
use, then click Open.
The pathname appears next to the file type in the External Editors tab.
The path is shown
for the application
set to open
still-image files.
To clear an external editor
1 Choose Final Cut Pro > System Settings, then click the External Editors tab.
2 Click Clear next to the clip type from which you want to remove an external editor.
The path changes to <None Set>.
Effect Handling Tab
The Effect Handling tab allows you to assign real-time effects processing to a third-party
video effects accelerator card or to Final Cut Pro (native software processing). Each codec
that appears here can be assigned to a different video effects accelerator card or to
Final Cut Pro. For more details, see
“Using RT Extreme.”
