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.
