When it comes to professional video editing, Masks are one of the most commonly used functions when animating. Have you ever tried to draw a Shape in Adobe, and, even though you clicked the Rectangle tool to create the object, you ended up activating some strange way of selecting areas? We present you Masks in After Effects.
Masks can be created in the same way as a shape. That's why this feature also allows the user to choose between using masks by default or making new ones. But what exactly does a Mask work for in After Effects?
A mask is a tool that allows you to include or exclude specific parts of a layer in order to add sharpness or define transparency as many times as you want to in your compositions.
To use this way of correctly selecting and not end up drawing a shape, first go to your Timeline and hit the layer you want to mask. Make sure you have your layer highlighted, then tap the Rectangle button.
You will know you are using the correct function if a new numbered element appears below your layer (usually called Mask 1) and if a no-colored square forms on your screen.
