Animating an Effect over Time

When compositing your scene, you will often want to animate the parameters of an effect over time. For example, you may want an object to fade in or out by changing the transparency level over time or by increasing the colour contrast on one of your drawings over a certain frame range.

To animate an effect over time, create a function curve by adding keyframes to the parameters you want to animate. To do this, you will use these views: Layer Properties, Node and Timeline. You can fine tune your animation using the Function view.
