hi,
i had this exact same problem and found this solution here:

—
Place your clips on the timeline (you can do this all at once to save time), and then use Project > Project Manager to Create New Trimmed Project.

If your original clips are from DV, and your project is DV, this will create a new file for each clip on the timeline.

Voila! Batch export.

hope that helps!
