Create a shape or motion Tween with the new shape you created.
When adding more frames to your movie, make sure you add the
same number of frames to each layer. Test your movie. To scrub through your movie to preview the
mask, lock both layers (you need to lock both the mask and the
masked layer to view the mask effect) and drag the red playhead
back and forth. You will see only the parts of your background
that are covered with the mask.
