You could pre-compose the watch face layer and then animate the mask, but actually doing the roto on the watch face layer is the least efficient way to do the roto. You could duplicate the footage layer, put the duplicate on top and then mask just the finger, You could add a colored solid above the watch face layer, change the blend mode so you can see through the layer and then animate a mask on the solid then use it as a track matte for the watch face layer. There are dozens of other ways to work out a solution. When I need to do roto and am using corner pin I usually prefer this method because it gives you a much bigger canvas to work with and stabilized everything so there are a lot fewer keyframes for the mask. Just drawing a mask on a corner pinned layer is not going to work because the mask is applied before the transformation effect from corner pin. The mocha Pro tracker can also deal with points that go on and off of the screen, so your track points should be obscured if a portion of your subject leaves the frame.It looks like you are using corner pin tracking from Mocha. The thing that makes this technique so much better is the fact that it uses a planar tracker rather than a pixel based tracker. Importing tracking data into After Effects.All of that tracking data can then be applied to your footage in After Effects for color grading and compositing. In this video tutorial created by Imagineer Systems (the people that make mocha Pro), we take a look at the impressive ways in which mocha Pro can track faces. If you’re working on a high-end film or commercial job, you definitely want to refine your tracks using mocha Pro as After Effects can leave some less-than-impressive results. That’s not to say that the built-in tracking features in After Effects aren’t useful.
Mocha Pro is by far a better tracker than After Effects due to its expanded functionality and spline-based track system. Think the After Effects face tracker is amazing? This mocha Pro tutorial explains why it may not be the best option for tracking.
