In today's exciting Adobe After Effects basics tutorial will cover Track Mattes! In my last basic tutorials I coveredmasking and Adjustment Layers so go check them out if you haven't yet
Once you know all about masking and adjustment layers, you are ready to move on to Track Mattes!
A track matte is an invisible layer that is used to control the opacity of the layer directly beneath it. In essence, they replace the alpha channel of the layer they are being applied to.
Let's assume you have 2 layers of footage on top of each other. The top layer will, if its opacity is set to 100% and you have not applied any masks, obscure the layer below it entirely.
However, you can add a track matte to the top layer to control its opacity. First, you will need to add a new layer directly on top of the layer you want to use it as a matte for. This layer can be anything you want: text, shapes, a video or another composition. In the following example I simply added a few shapes onto my new layer:
Now let's look at the different type of track mattes in Adobe After Effects.
