  1. Nice.
    You can actually solve this problem directly by using the movie clip editor mask using the z combine node.
    You basically use the render and z of the scene as the first input.
    For the second input you connect the image and enter z manually. In this second input you have already been able to set the alpha using the mask. Here a screenshot:

    With this way you can use all the mask tools, especially if they are animated.

    Thank you,
