Apple Final Cut Pro 7 - Manual (Page 1594)

Because the Media Manager tries to preserve media referenced by clips in your project,
it is necessary to delete the original master clip (which refers to the entire length of the
media file) so only the subclip media will be preserved.
2 Rename your subclips with descriptive names.
When the Media Manager creates new media files, they will be named after these subclip
names.
3 Select all of the subclips that you created from the master clip you just deleted.
Important: The media for any subclips you don’t select will be lost. To be safe, you can
move all the subclips whose media you want to retain to one bin, and the subclips you
don’t want to preserve to a different bin. Then select the bin of subclips you want to
preserve.
4 Control-click one of the selected subclips, then choose Media Manager from the shortcut
menu that appears.
5 In the Media Manager, make the following selections:
Deselect this option.
Choose “clip names” from
this pop-up menu. This
option names your media
files using the descriptive
subclip names instead
of numbered variations
on the original
media filename.
Choose “Use existing”
from this pop-up menu.
Select this option.
6 Click OK.
