I am trying to create a composite scene very similar to the introduction scene seen in almost every James Bond movie. This is the scene with the sliding circle that pans from left to right across the screen, then "irises out" to another composite that has a gun barrel mask with a, 007 walking right to left, video in the center hole of the gun barrel mask. To see what I mean, look at almost any Bond movie, its right at the beginning.

Before I tried to apply this technique to my project I wanted to test Vegas's ability to do this type of scene, so I've mimic-ed one of the Bond movies I have.

The problem I'm having is two fold. First, Masks don't seem to work properly in Vegas. The online help steps DO NOT WORK. Second, to do this shot you actually need a composite of a composite. The parent composite comtains the Iris mask and the child. That child contains its own parent, the gun barrel mask and the child is the "007 walking" video shot.

I have managed to create the "sliding circles" part, which I was happy with, using a media generator (circular color gradient - tweaked). But the gun barrel mask with video I can't seem to get to work. Like I said masks don't seem to work, going by the online help steps.

Any ideas?
