1 How can you animate a 3D layer?

2 How are 3D lights handled in After Effects?

3 What is a point of interest?

1 Animating a 3D layer is similar to animating a 2D layer, except that you can move the object on three axes: the x axis, the y axis, and the z axis. You can animate other Transform properties, effects, and other settings just as you would those for a 2D layer.

2 In After Effects, a light is a type of layer that shines light on other layers. You can choose from among four different types of lights—Parallel, Spot, Point, and Ambient— and modify them with various settings.

3 Cameras and lights include a property that specifies the spot in the composition at which the camera or light points. By default, this point of interest is set at the center of the composition, and the camera or light’s view is automatically oriented toward it. You can change this behavior by choosing Layer > Transform > Auto-Orient. Of course, you can move the point of interest at any time.

In this lesson, you’ll learn how to do the following:

􀁴 Use motion stabilization to smooth out a shaky camera shot.

􀁴 Use single-point motion tracking to track one object in a shot to another object in a shot.

􀁴 Perform multipoint tracking using perspective corner-pinning.

􀁴 Use Imagineer Systems mocha for After Effects to track motion.

􀁴 Create a particle system.

􀁴 Use the Timewarp effect to create slow-motion video.

This lesson will take approximately 2 hours to complete. Copy the Lesson13 folder into the Lessons folder that you created on your hard drive for these projects (or create it now), if you haven’t already done so. As you work on this lesson, you’ll preserve the start files. If you need to restore the start files, copy them from the Adobe After Effects CS5 Classroom in a Book DVD.

After Eff ects CS5 provides advanced motion stabilization, motion tracking, high-end eff ects, and other features for the most demanding production environments.
