Exchange
Exchange is a variant of the Overwrite option, but instead of dropping the entire
duration of the new object into the project, the duration of the existing object is used.
For example, if you drag a 30-second clip over a 5-second clip, choosing Exchange
swaps the existing 5 seconds with the first 5 seconds of the longer clip.
Similarly, if you try to exchange a 10-second clip with one that lasts only 5 seconds, the
first 5 seconds are replaced, and the remaining 5 seconds would remain.
The Exchange option transfers any filters, behaviors, and keyframes from the original
object onto the new object.
Sequential
This drop menu option is only available when you are dropping multiple objects into
the Timeline. Sequential drops objects one after another in the Timeline. For more
information, see “
Adding Multiple Clips to the Timeline
To composite an object:
1
Drag an object from the Library or Media tab into the Timeline tracks area. As you drag,
a tooltip appears at the pointer to tell you the frame number at which you are located.
2
When you reach the frame where you want the new object to start, position the
pointer over the object you want as the background, and keep the mouse button
pressed until the drop menu appears.
3
Choose Composite from the drop menu.
The new object is composited into the project.
To insert an object:
1
Drag an object from the Library or Media tab into the Timeline tracks area. As you drag,
a tooltip appears at the pointer to tell you the frame number at which you are located.
2
When you reach the frame where you want the new object to start, keep the mouse
button pressed until the drop menu appears.
3
Choose Insert from the drop menu.
The new object is inserted into the track, breaking the original bar into two, and
pushing the frames after the insertion further out in time.
