The project is nearly finished. All that's left is to see how it works with the background and possibly to add a few advanced touches to polish it.
We'll start by turning on the Background layer to see how our project plays against the background.
1.
Click the check box next to the Background layer to turn on the layer.
2.
Press the spacebar to view the project in the Canvas.
It looks pretty good, but it would be even better if the Bottom sublayer of pictures went behind the globe. No problem. All you need to do is move the Globe Corner movie from the Background layer to the Photographs layer.
NOTE
The more elements that you add to a project, the more Motion (and your computer) have to process the project. Motion caches each frame in video memory (VRAM) as you play the revised project. After you've played through the entire revised project in the Canvas one time, you should be able to see it play in real time.
3.
Click the disclosure triangle for the Background layer to view the contents of the layer.
4.
Drag the Globe Corner object upward from the Background layer to the Photographs layer and release.
The Globe Corner object appears at the top of the Photographs layer.
The bottom row of pictures now moves behind the spinning globe.
