Complicated Tracking Shot Stabilization

Hello!

I’m trying to stabilize a complicated tracking shot and haven’t been able to find a tutorial that addresses my situation, which I believe has to do with assigning multiple tracking points at different times, and being able to combine them without favoring the other.

In the clip (link below) I’ve stabilized the first part of the video pretty well (it still warps a bit and you can see where the stabilization ends and jumps slightly at :13) but now I’d like to stabilize the second half of the clip as well without cutting off the woman on the left, while also combining the first half that I’ve already stabilized. Would love any insight on how to do this properly.

Really appreciate your help!
