Summary  
This chapter covers how to create and adjust vector masks and track mattes using shape and pen tools, apply Boolean mask operations (add, subtract, intersect, difference, invert), and link layers to inherit transforms for coordinated animations.

General domain of usage  
Video compositing

There are two main types of masks in After Effects: **Vector Masks** and **Track Matte**.

In this chapter, **you've learned**:
- How to create and adjust masks;
- How to use the Pen tool for precision;
- How to apply one layer as a mask for another;
- How to link layers to animate them together.

Note

What is the purpose of masks in After Effects?

This course provides a comprehensive introduction to Adobe After Effects, covering essential tools and techniques for animation, motion graphics, and visual effects. You'll engage in precise practice, learning to create full animations and advanced transitions in dedicated chapters. By the end, you'll have the skills to craft dynamic animations and high-quality video content through hands-on projects.

Explore the core interface and functionality of After Effects, covering how to navigate compositions, layers, and essential tools. Learn effective project organization and develop a solid understanding of basic transformations, forming the foundation for more advanced animation work.

The focus is on mastering key animation principles, including keyframing and easing, while applying them to create a complete animation and designing motion graphics transitions in practical examples.

Explore advanced features such as chroma keying with the Keylight effect, using masks to refine visuals, applying Adjustment Layers to multiple elements, and improving project organization through pre-composing. Practice creating professional transitions and master techniques like zooms and whip pans with precise execution.
