Review Questions

1 What is a mask?

2 Name two ways to adjust the shape of a mask.

3 What is a direction handle used for?

4 What is the difference between an open mask and a closed mask?

1 A mask in After Effects is a path, or outline, that is used to modify layer effects and properties. The most common use of masks is to modify a layer’s alpha channel. A mask consists of segments and vertices.

2 You can adjust the shape of a mask by dragging individual vertices, or by dragging a segment.

3 A direction handle is used to control the shape and angle of a Bezier curve.

4 An open mask can be used to control effects or the placement of text; it does not define a region of transparency. A closed mask defines a region that will affect the alpha channel of a layer.

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

􀁴 Place Deform pins using the Puppet Pin tool.

􀁴 Define areas of overlap using the Puppet Overlap tool.

􀁴 Stiffen part of an image using the Puppet Starch tool.

􀁴 Animate the position of Deform pins.

􀁴 Smooth motion in an animation.

􀁴 Record animation using the Puppet Sketch tool.

This lesson will take approximately an hour to complete. Copy the Lesson08 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.

Pull, squash, stretch, and otherwise deform objects on the screen using the Puppet tools. Whether you’re creating realistic animations, fantastic scenarios, or modern art, the Puppet tools expand your creative freedom.
