It looks like you're trying to mask the image by overlapping multiple
sprites. Instead, you need to create a single sprite which has its
alpha channel set correctly (and it's rendering mode set to "over").
You should be able to do this by connecting the sprite's image input
to the movie, and its mask input to your mask generator.

Hi Ron - cheers or your help,
I'm using sprites and its rendering as it should but I'm just not
sure how to go about achieving the affect I want - The attached
composition should work fine now?
Regards - James

Unfortunately, I can't open your test composition (Patch with name
"SpookyReceivePatch" is missing"), but I'm wondering if your movie
is being rendered on a billboard instead of a sprite?
In my experience, billboards always render transparent areas as
black.

Hi All,
I have a composition where I'm trying to frame some videos (So
they don't have square edges) and move them around. I'm placing
a mask image with a black border and transparent center just in
front of the movie (pic in attached example) which works great.
The thing I can't figure out though is how to mask around the
edges of the video properly so that when they move over each other
I can't see the mask image - see attached composition for a demo
with pictures instead of movies.
Would there be some way to use a pixel shader to not render any of
the black pixels? I know at first this seems to look like it
would just remove the mask image (exposing the video again) but I
was thinking I could render the video and frame in a "render in
image" patch first? that way if the black pixels (the frame) are
not rendered then I can see any other movie objects behind the
current.
Cheers - James
