300 Part VI Rough Editing
Duplicating a Sequence
If you want to test changes to your edited sequence that are more extensive than a few
levels of Undo will permit, or if you want to create several versions of your program for
a client to review, you can duplicate your current sequence and make changes to the
duplicate. Changes you make to a duplicate of a sequence do not affect the original in
any way. You can make as many duplicate sequences as you like, renaming them in the
Browser for reference and reediting them as extensively as you want.
To duplicate a sequence:
1 Select the sequence in the Browser.
2 Do one of the following:
 Choose Edit > Duplicate.
 Control-click the sequence, then choose Duplicate from the shortcut menu.
 Press Option-D.
3 In the Browser, enter a new name for the duplicated sequence.
Sequences are independent of each other, so changes you make to the copied
sequence do not affect the original sequence or its rendered files.
Note: When you duplicate a sequence, all clips in the new sequence are affiliated with
the same master clips as the clips in the original version of the sequence.
Copying a Sequence into Another Project
If you have more than one project file open in the Browser, you can copy a sequence
from one project and paste it into another project.
To copy a sequence from one project into another:
1 Select the sequence in the Browser.
2 Choose Edit > Copy (or press Command-C).
3 Open a new project and select its tab in the Browser.
4 Choose Edit > Paste (or press Command-V).
You can also copy a sequence into another project window by dragging.
