Is it possible to animate a mask position with a null without moving the whole layer that the mask is on? I need to add the mask to a layer but keep that layer stationary while moving the mask around. I have tracked the position of the null using the Motion Tracker on the source video layer but can't seem to get the mask to move on its own.

Copy the mask to a solid, parent the solid to the null, and use the solid as a track matte. Does the same thing. Besides, you can't parent a mask to a null.
