What is the use of Precompose in After Effects?

Precompose layers Precomposing layers places them in a new composition (sometimes called a precomposition), which replaces the layers in the original composition. Precomposing a single layer is useful for adding transform properties to a layer and influencing the order in which elements of a composition are rendered.

What does pre render mean in After Effects?

Pre-render Select the pre-comp in the Project window and choose Composition > Pre-render.

How do I cancel pre compose?

What is alpha matte?

What is collapse transformations in after effects?

By using the Collapse Transformations switch you can give yourself the ability to adjust the transformation data for multiple 3D layers from a single composition layer. In a way, this makes your pre-comp transformation data act as if it was a parented null object to all of the 3D layers housed inside.

How do I merge two compositions in After Effects?

To add to @RobShultz’ suggestion, do the following. Create a new composition. Set it’s length to how long you want your final render to to be. Drag the comps you created onto the timeline. This is called nesting of comps. Arrange them as you wish on the timeline. With this new timelines selected, render your project.

What is alpha channel used for?

The alpha channel (also called alpha planes) is a color component that represents the degree of transparency (or opacity) of a color (i.e., the red, green and blue channels). It is used to determine how a pixel is rendered when blended with another.

Why is alpha matte not working?

It looks like you have created a Mask over a shape layer but the alpha matte is not using the mask because you have no content in this layer, it is empty.
