I am trying to use my eyes (from a video of mine) to overlap the monalisa's eyes of a monalisa still image.

LAYERS:

VIDEO 3 - EYES MATTE (I BUILT IN PHOTOSHOP WITH TRANSPARENCY from a monalisa export frame)
VIDEO 2 - MY VIDEO
VIDEO 1 - MONALISA PICTURE

I am using track matte key in MY VIDEO setting layer to use VIDEO 3

The problem is despite the matte is in monalisa's eyes, it is black, not showing my eyes as should it be.

What am i doing wrong?
