Does anyone know of Python code to both remove keyframe noise and also perform keyframe reduction somewhat like the timeline keyframe reduce function? I'm importing face capture FBX files produced by the Apple ARKit which contains multiple morphs with keyframes on every frame. Some keys have very small changes that produces a "vibration" look, or sudden changes "spikes" that I manually delete. Then I perform the keyframe reduce function on each morph not only to remove keys, but to create a nice smooth curve giving the animation a more fluid, natural look.

Another option is if anyone knows how (and if) the Cinema 4D keyframe reduce function can be called from Python.

I'm using Cinema 4D R21.
