If it's possible I would like to do a special picture in picture effect. I can easily create a standard PIP. What I would like to do is have the PIP play for a few seconds & then have is slowly dissapear gradualy but not to just fade away all at once but rather have it fade away from left to right. In other words the clip that forms the PIP would have to have it's transparency gradually changed over time but done in such a way as to fade from one side to the other. Can this be done?
