My goal is to apply several keyframes to a property of a layer and then set them all as "Easy Ease": essentially, I'm looking to achieve the exact same effect as doing the following in After Effects:
Playing keyframes, without changing their default interpolation (so leaving them as linear)
Selecting all keyframes just placed.
Pressing F9 to apply Easy Ease.
I know how to do this when using After Effects manually but not when writing scripts. I would like to achieve the exactly same effect with After Effects scripting. I've come close, but I'm not quite there. For example:
master_comp.layer(1).property("Opacity").setInterpolationTypeAtKey(1, KeyframeInterpolationType.BEZIER, KeyframeInterpolationType.BEZIER);
Will change the newest pre-existing linear keyframe to Bezier, but it will not apply Easy Ease to it; they are not the same.
How can I apply Easy Ease to all the keyframes for a given property of a layer?
