Apple Final Cut Pro 6 - Manual (Page 369)

36 Part I Organizing Footage and Preparing to Edit
Final Cut Pro places new subclips in the same Browser bin as the original clip they
came from, automatically appending the word “Subclip” to the name and numbering
each successive subclip you create from a particular clip. For example, if the original
clip is named “Debra enters cafe,” the first subclip is named “Debra enters cafe Subclip,”
the second is “Debra enters cafe Subclip 2,” and so on. When a new subclip is first
created, its name is highlighted and ready to be changed.
You can rename subclips, move them into different bins, and organize them in any way
you choose. After you’ve created your subclips, you can open them in the Viewer and
set new edit points, just as you can with any other clip. The original clip remains in the
Browser, but is completely independent of your subclips. Any changes you make to a
subclip are not applied to the original clip.
Numbered subclips are
placed in the same bin as
the master clip.
