Making an alpha channel

Hi,

Im a Vegas Movie Studio newbie. I am trying to create an alpha channel by using the Chroma Keyer but no matter what I do I don't seem to get an alpha channel when I render the file.

The video shows a guy with black background. With the Chroma Keyer I select the black color from the background, and black background gets transparent and shows whats underneeth. So far so good.

But what to do next? How do I render the video so the transparency is added to the video-file? I have tried to select Alpha channel: Premultiplied and then render the video to several different formats and codecs but when I import it to flash there is no transparency there.

Any help is a appreciated.

Best regards,

Gibbah
