Apple Final Cut Pro 7 - Manual (Page 34)

If you need to finish your project on a different editing workstation, you can export your
project to an interchange file format such as Edit Decision List (EDL) or Final Cut Pro XML
Interchange Format. You may need to output on another system if you work with
uncompressed video, do lots of real-time effects processing, or require specialized video
monitoring. For more information, see
“Using Final Cut Pro XML and QuickTime Metadata.”
You can also refer to “Offline and Online Editing.”
