Final Cut Express 1.0: Extracted Audio From iMovie Projects Contains Original Files
Projects imported from iMovie where the audio has been extracted and changed contain audio tracks for both the original audio and the changes to the extracted audio. For example, an iMovie project with extracted audio that has been deleted in iMovie will still have the original audio in Final Cut Express.
Symptom
Changes to extracted audio in iMovie are not reflected in Final Cut Express
Solution
Make the desired changes to the audio tracks from within Final Cut Express.
