Transparent Animations?

Hello,
I'm trying to create an animation of a shirt spinning front to back and repeating in Vegas. I can get this part done. But when I use the rendered avi as a button in DVDA3, there is a black background around the shirt. So it spins inside the black box. Is there a way to render it and keep the transparent back ground and only show the shirt spinning?
If you can help, thanks!
Brad

What does the background look like, that you want the transparent avi on?

my background is an avi, so it's moving. Otherwise I could do some photoshop and add it as a background in vegas, i think.

Or is there anyway to convert the avi to a gif w/out having to save all the little pictures and run them through a animation builder?
Thanks,
Brad

I like Videomach. It can convert your AVI to a group of stills. If you have Vegas 6 or
later it has the ability to read sequence files. (shirt000.tga shirt001.tga etc)

You can make an alpha based on intensity in your photo editor.
Now if you have a solid background use your highlight
mask to hide nonselected buttons. Check for previous posts on this subject.

White shirt on track 1.
Background avi on track 2.
Key out the white shirt. If it's a static shot, do it in Photoshop and save as a PSD or PNG to keep the alpha channel.
White shirt is now keyed over the background.
Render out in the desired format.
Is this what you want to do?

You need to build your entire menu in Vegas. Start with your background, then put your spinning shirt on it at the size and location needed. The rendered AVI becomes a motion menu in DVDA and you put your buttons with the highlight mask where you need them.
