Hi there. Im having problems with simply tracking a mask. I have two groups of different footage, I have cut a hole in the first using the mask and inverting it and I can see the below layer of footage. now I want to track that mask to the movement of the top layer (trying to keep it over the eye of the subject. So I add the match move behavior to the mask and for some odd reason I dont get any analyse options. I can choose between four corners or transformation but I cant analyse... Please can someone tell me what im doing wrong??
You could first use an Analyze Motion behavior on your background clip, then apply a Match Move behavior to your foreground, and then drag your Analyze Motion behavior (with embedded data) from Layers into the Match Move's Source well (Inspector>Behaviors>Match Move>Source).
