Export Flash as Transparent MOV

Is it possible to export a flash movie with a transparent background as a .MOV.

I don't mean for embedding in a website, I mean the actual .MOV (or .avi).

What I'm trying to accomplish is that I have a flash animation that I want to embed in a WPF application. I don't want to use a Browser within the WPF because of all of the issues that surround the browser control (has to be topmost control, etc).

So my solution was to export 开发者_如何学Pythonsaid animation as a movie and play it in the MediaElement control. The only problem is that I need the background to be transparent, and I can't find a way to do this.

Any suggestions or alternative solutions would be most welcome.

The comment above:

in the Flash IDE:

File > Export > Export Movie > ...choose Quicktime format > tick 'Ignore stage color(generate alpha channel)' and you're done.

This works for actionscript generated graphics too. Not much code there.

I found an interesting thing that worked! In the dialogue box you need to change the type of export to 'animation' if you have made an animation. Simply ticking 'ignore stage colour' did not work until I had changed the type of .mov to a animation.
