How Do I Add an Animation Layer in After Effects?

You can add an animation layer in After Effects by creating a new solid layer. Here's how:

1. Open After Effects and create a new project.
2. Click on the "Layer" menu in the top menu bar.
3. Select "New" > "Solid."
4. Choose the desired color, width, and height for your solid layer.
5. Click "OK."

The new solid layer will appear in your timeline, ready for animation. You can now add animation keyframes to this layer to create your desired effect.

Example:

Let's say you want to create an animation of a circle expanding outwards. You can create a solid layer, set it to a circular shape using the "Ellipse Tool," and then animate its scale property over time.

Practical Insight:

Solid layers are versatile and can be used for various animation purposes, including backgrounds, shapes, text, and more. They are a fundamental building block for creating complex animations in After Effects.
