If your subject is stationairy you can use the Track Matte effect.
Draw her eyes in the Titler in white.
Put that on track 3 with a Blur for feather.
Duplicate track 1 to track 2 and add the TM effect and set it to track 3.
If you subject is not sitting still then its a job for AE.
Thank you!! I will try this now
okay, I tried this, but my subject is not sitting still.
Could you explain how to do it with AE?
Just how much movement is there?
While AE is probably the better program for this, one can Keyframe the Fixed Effect>Motion>Position for the Track Matte, in PrPro, to do some "following." If the size also changes, one would be able to accommodate some of that, with Motion>Scale on the Track Matte.
Much movement, and then After Effects would be the way to go.
