Apple Final Cut Pro 7 - Manual (Page 1288)

Important: Audio clips from the original QuickTime files are not imported into Shake.
Video timing changes you make in Shake can cause audio sync problems if you import
the finished Shake composite back into your original Final Cut Pro sequence.
Unsupported Media and Effects
The following items are not transferred when exporting Final Cut Pro sequences to Shake:
• QuickTime audio tracks
• Standalone audio files
• Still-image files
• Generators
• Composite modes
• Parameters in the Motion tab
• Filters
• Transitions
Sending Media from Shake Back to Final Cut Pro
When you've finished working in the Shake script that was generated from Final Cut Pro,
you need to render the originally created FileOut node. The newly rendered media file
takes the place of the placeholder QuickTime file, ready for use by the original Final Cut Pro
project.
When you reopen the Final Cut Pro project file containing the original placeholder
QuickTime file, you'll need to use the Reconnect Media command to relink the clip in
your sequence to the media that was rendered out of Shake.
