Exploring spatial keyframes

Now earlier in this lesson, you animated the snowflake along a curve,…but I thought it'd be useful to give you a better, guided tour of how the…different keyframes work in the Comp panel.…The position keyframe in the Comp panel, by the way, is called a spatial keyframe.…Spatial simply means space.…It has a value on X and Y, unlike say Opacity, which has a value in percent.…When I turn on the stopwatch for Position and create the first keyframe and,…then I will go to a later point in time and I'll move the Snowflake,…it might look like After Effects creates motion paths in a straight line.…

So you might think if I make a third keyframe and drag it over here, this…would be a straight line, but it's not.…The middle keyframe--actually all of the keyframes--are defaulting to Auto Bezier keyframes,…Auto meaning automatic.…You can think of it like After Effects is making an automatic curve.…Now where does it get this curve from?…Well, you see there is two dots to the left and right of the keyframe, and you…
