How do you expand a mask using keyframes?
Blurring faces using motion tracker and a fixed elliptical mask only is suitable only when a subject’s distance remains relatively static.
Some of my videos have a subject which approaches the camera at a brisk pace, and his/her faces often enlarges by 2-3 times, reducing my original mosaic-mask down to the size of their forehead.
Motion tracker generates keyframes on target, but how do you set up the mask to both track and enlarge as the video progresses?
Thanks in advance.

If you’re using motion tracker, see if you can get a good track for the scale property.
