In the Comp Window, right-click on the first Keyframe (small 'x'
preceding the Path) to open the Keyframe options menu.
7
Select
Keyframe Interpolation
Spatial Interpolation:
Continuous Bezier
.
Magnify the Comp Window and
center the view on the first Keyframe.
A short line has been added coming
out from the Keyframe's center - this
is a Bezier vector handle. Dragging on
this handle will impose a non-linear
change to the layer's path.
8
Drag the first handle in any direction to see the object's Path bend.
9
Right-click on the end Keyframe and apply the same
Continuous
Bezier
Spatial Interpolation.
10
Drag the end Keyframe's handle around to exaggerate the path.

Save your work, then press the 'Space Bar' to preview the motion.
Using the Space Bar imposes another form of RAM Preview - Preview with
Paths. This is helpful for examining where objects intersect each other, or
interact with other layers in the Comp Window.
Reactivate the original
Temporal
layer's Video switch and compare their
motions. The
Spatial
layer now follows a distorted path rather than the original's
linear path. Open the Position property of the
Spatial
layer - neither of the
Keyframes has any indication a Spatial Interpolation has been applied.
Generally, you don't need a Keyframe Marker icon change to identify the
Spatial Interpolation - clicking on a layer to display its path will be clue enough.
However, the only time you can see the handles of a Bezier path is to select the
property's Keyframes - then the handles will display in the Comp Window.
Interpolation and the Pen Tool
With the project you just created open, activate
the Pen Tool (G). This tool allows you to
manually insert, delete, or modify any Keyframe
