Creating a Master Clip by Duplicating a Master Clip
You can intentionally duplicate a master clip to create a new, unrelated master clip,
which will then have its own affiliate clips. However, you should do this sparingly
because the main reason for a master clip is to have only one clip per project that
represents a media file on disk.
To create a new master clip by duplicating a master clip, do one of the following:
m
Select a master clip in the Browser, then choose Modify > Duplicate as New Master Clip.
m
Control-click any master clip in the Browser, then choose Duplicate as New Master Clip
from the shortcut menu.
The clip is duplicated, and the new clip is an unrelated master clip.
