Rotoscoping

Hey Nick,

Did RemusBlueFX's advice assist you? Let us know.

Thanks!

I'm assuming you are rotoscoping the edge of the actors face. Any time you roto something that is moving in the frame you have to figure out a way to match the camera blur on the mask and even more importantly, on the subject - your halogram. The best technique depends entirely on the shot and on the motion.

If I'm understanding the shot properly and the camera movement then your best option would probably be to use CC force motion blur on the matte and also on the hologram. Other options include directional blur and feathering the matte. Since you didn't provide a screenshot of the entire AE UI with the modified properties of the layers you are having problems with this is only a guess. It would also help to see the video instead of just a couple of screenshots.

Maybe this tutorial will help a bit. It shows how I matched the look of some inserted video. I've cot a couple more motion tracking and compositing tutorials in the works that actually cover this subject but I'm in the middle of a production right now so you'll have to wait.  I'm guessing about the camera movement in your shot and I think the mocha tracking technique is not the right approach to your problem, but the end of the tutorial where I match the insert to the video may be helpful.
