Imported FBX animation, remove jitter by smoothing keyframe curves?



I’ve imported a Houdini sim through FBX, the animation slightly jitters, some nervous keyframes here and there. I was wondering if I can make out of all keyframes one f curve that smooths out the small irregularities, no corners, something like chamfer for f curves.

I’ve tested making the points soft which already helps but prefer to have not a point for each single keyframe.
