I´ve attached the same animation made with Adobe Edge Animate & Hype. Look at the gradient (gray to white) background that apeares into the graphic. The way I do that is grouping (masking) the gradient rectangle. Then I join both lateral sides of the mask (moving both of them to the center or a specific point horizontally) and then stretching them to its original size. The problem is that when I stretch the left side to its original position I can´avoid a movement of the masked image. So I have to move that image manually in order to keep the correct position (I just want to move or strecth the mask keeping the image always in the same place.
I hope you understand the problem. Sorry for my english…
