Summary  
This chapter introduces how to apply a set of effects to multiple elements simultaneously by using a shared parent layer that propagates the effects downward, and how to encapsulate groups of elements into a single composite module to simplify and organize complex structures.

General domain of usage  
Video compositing

There are two essential tools for managing effects across multiple layers — **Adjustment Layers** and **Pre-Comps**. These features help you organize your project and apply changes more efficiently.

**Adjustment Layer** looks like an ordinary empty layer, but in reality, it applies all the effects added to it to all the layers below.

**Pre-Comp** is essentially a smaller composition inside your main composition. As your project grows in complexity, pre-composing groups of layers helps keep your main composition cleaner and improves workflow efficiency.

Definition

**In this chapter, you've learned**:
- How to use Adjustment layers to apply effects to multiple layers;
- How to Pre-Compose layers to simplify and organize complex projects;
- How these tools improve workflow and project management.


What is the function of an Adjustment Layer in After Effects?


What is the main purpose of Pre-Composing layers?

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.
