Once you have added a generated media event and modified its settings, you can duplicate it. For more 
information, see Duplicating events on page 103. 
When you duplicate a generated media event, you have two options: 
 Select the Create a new copy of the source media radio button if

In the second example, track two is the child track of track one (the parent track), and the compositing 
mode of track one is set to 
Mask. This parent/child relationship was set up by clicking the Make Compositing 
Child
 button () in the track list for track two. This makes the text in track one act as a mask over track two, 
allowing the fire to show through the mask (i.e., the text). The region outside of the text is still transparent, 
but there is...

In the first example, the two tracks intersect along their rotation axis. In the second example, adding a 2D 
track above the “cool” track causes it to be rotated in 3D and composited as a 2D image so the “hot” text is 
displayed above it without intersecting.

Examples of various 3D compositing scenarios
In the following examples, track two (blue-and-yellow checkerboard) is rotated forward in 3D space, track 4 
(green-and-gray checkerboard) is rotated backward in 3D space, and track 3 (red-and-white checkerboard) is 
a 2D track.
