FileIn the Source Material

1.	Open Shake.
2.	FileIn all the .iff files from the Lesson11 folder. You should have the following eight clips: car_mask, laser1, laser2, laser_reflection, logo, mercedes_comp, woman, and woman_roto. Take a moment to view the final composite before starting.
3.	Find the mercedes_comp clip and load it into the Viewer.
4.	On the Globals tab, set the timeRange to 1-70.
5.	Click the Home icon at the bottom-right of the interface to set the Time Bar range.
6.	Click the Flipbook icon and play the clip once it is loaded. What you have here are your standard computer-generated laser beams and reflections added to a live-action background plate of a woman walking in front of a sports car.
7.	Repeat steps 36 to play the woman and laser clips.
8.	Load the woman_roto and car_mask clips into flipbooks and play them. The car_mask clip will appear black because it contains only an alpha channel.
9.	Press the A key with your cursor over the car_mask flipbook to display its alpha channel.
10.	Play the car_mask flipbook. The car_mask and woman_roto clips will be used to isolate certain elements in the layering process.
11.	Close all open flipbooks.
