Introduction to the Graph Editor

- [Narrator] Animation is represented in…After Effects in a few different ways.…We see animation taking place in the composition window…where our layers move around the screen.…And we've seen animation expressed as key frames…in the timeline via the default layer bar mode…where layers appear as colored bars…that are stacked on top of each other.…After Effects has another method to visualize…our animation in what's know as the graph editor.…And so to get to the graph editor,…let's click on this button right here.…And you'll notice there's nothing in here and…that's because we have to have a layer selected…with a property that has key framed animation.…

So let's select our position key frames here, and this is…just our linear base runner guy that runs across.…And it's important to note that the graph editor…is a place where the interpolation of key frames…can be viewed as either a speed change,…how fast an animation is taking place…or as a change in value for a given parameter.…So really it has two functions, this graph editor…
