I have a shot where the camera moves closer on a girl (Dolly shot), but we shot this with the intention of removing her face (artistic purposes), almost as if shes slenderman with a girls hair, so it just looks like skin over where her eyes nose and mouth would be. Almost like you were to take the bandaid tool to her face in photoshop (spot healing brush tool). How would I achieve this?
It's a little complicated to explain here but I would track the face in Mocha and then export corner pin data and apply it to the image that is going to replace the face. You will probably also need to do a little soft edge Roto.
You will need to have a good understanding of corner pin tracking and compositing as well as a good handle on Roto.
