About the course

The Timeline panel is one of the main panels in After Effects used for creating animations. Each composition has its independent Timeline panel, where you can animate layer and effects properties, position layers in time, and change the layer blending modes. In this tutorial, I’ll teach you how to work with two-dimensional layers, the stacking order of the layers controls, and many layers switches to create the effect you want.
