How Kease solves AE Spatial Interpolation limitations
The spatial interpolation controls the route taken by an object. In other words, the path taken by an object to move from one position to another.
Spatial properties like ‘Position’ or ‘Anchor Point’ get a special treatment by Kease when they are the target of an easing curve change.
Look what happens when Kease applies an easing curve with anticipation between two consecutive keyframes:
As you can see, a new keyframe has been created. As a matter of fact, there is a limitation in the way After Effects handles multi-dimensional spatial properties: no overshoot or anticipation effect can be achieved by simply adjusting their easing curve.
There are two solutions though:
- you can separate the property dimensions first (right click on the property and choose “Separate Dimensions”) and then apply the easing curve.
- alternatively, you have to create additional keyframes. But you don’t have to worry, Kease will do the job for you automatically.
Non-linear Spatial Interpolation treatment
The following example depicts what happens in case an Extended Preset is applied to the position property of an object which has a linear spatial interpolation:
In the next example the spatial interpolation has been changed from linear to bezier. As you can see the object moves beyond the path limits following the tangents. This is how Kease handles non-linear Spatial Interpolation. How cool is that?
