I’m not completely sure what you are looking for, but enclosed are a couple of screen shots for you to look at.
Regarding my workaround: Since there was no part of the clip that showed the entire face, I chose the a frame closest to what may cover all the frames as my starting frame for stabilization. In doing so, any frame where a portion of the face appears that was not in the reference frame, the image would be smeared. So, what I did to resolve this was to take the initial stabilized rendering in After Effects and duplicate it the number of times to match the smeared instances in the clip. Then, with each occurrence of smearing, I would go to the worst smeared frame in the run and re-stabilize that duplicate clip in Mocha Pro to that particular reference frame. I would do this for each of the smeared points in the clip and adjust each Mocha Pro rendering for the span needed to cover each smeared area (usually there were two or three instances). Then, I precomposed each re-stabilized clip (trimmed to the corresponding span in the timeline) so that I could then mask (as an Add) the area of the smear replacement. Likewise, in the original stabilized clip, I precomposed it as well and masked the smeared frames to subtract them from the original. This allowed me to match the frames with the correct timing, position, and effects rendering, and repair the smeared areas of the image.
I hope that makes sense.
