Stabilizing and Match Moving Plates

Hi Pete,

I'm having some trouble stabilizing and match moving two plates. One is my clean plate and one is my original footage. I have tracked both plates and set them both to stabilize and then I created a roto for the patch where I need to bring over the clean plate. My problem is that my clean patch is still moving ever so slightly and I don't know how to fix this. I have tracked both plates in the exact same place and have picked a point that is close to where I am doing the roto. Are there any tools in the tracker that I can use to help smooth out the shifting or do I need to just keep trying to find a better place to track on the plates?

Thanks Pete!
