<p>In After Effects CC, masks can be made into tracking masks. Right click the mask and you should see a context menu with <strong>Tracking Mask</strong>. Select it and the mask can be tracked to the video it is applied to.

Great tip that it's now possible to track the mask! Seems not that accurate, but works as expected. Thanks.
