CHAPTER 4 190
Editing Video
•
Update identical scattered sequences all at once. For example, if you create the virtual clip
described above and use the virtual clip in your video program ten times, you can simulta-
neously update all ten instances of the virtual clip just by editing the clips in the area of the
Timeline that defines the virtual clip. And if different effects are applied to each instance of a
virtual clip, the different effects are preserved for each instance. If you had copied and pasted
the sequence instead of creating a virtual clip, you’d have to update one sequence and then copy
and paste the update nine times, or edit each copy individually.
•
Apply settings more than once to the same clip. For example, certain effects can be
achieved only by combining transitions. However, you cannot apply more than one
transition to the same point in time—unless you use a virtual clip. For example, you can
apply a transition between two clips in the Timeline outside the main program, create two
virtual clips using the clips on either side of that transition, and move the new virtual clips
to the Timeline. The first transition you applied is now inside each virtual clip, so now you
can apply a second transition between the two virtual clips.
Copying and pasting a sequence multiple times in the Timeline creates many objects in the Timeline.
Virtual clips achieve the same goal in a much simpler way.
When creating virtual clips, keep in mind the following:
•
A virtual clip always represents the current state of the original Timeline area on which it is
based, so if you edit that original area in any way, you will affect the virtual clips based on it.
