If you removed the Anchor Point keyframes and reset its value then that’s one part of the step (it should be noted that mochaAE CC2014 works differently from previous versions by not exporting the Anchor Point data). Your other options now, in AE, is to look at whether you require the Rotation and Scale keyframes. Often times, these two data types are not what you need – either you delete all the keyframes or a very basic, 2-keyframe manual solution does the trick.
As for smoothing out AE’s own tracker data, you may want to track multiple times and then average out the tracking data using Expressions – do a COW search to find out the mechanics on this.
