Quicktime to Flash with Alpha i.e. Contribute Flash on Macromedia site

Hi,

We have been trying to emulate the cutout video of the “/hassle” swf that is demonstrated on the Contibute Flash on the main page of Macromedia.com.

We have tried a PNG sequence, but it is way too much K. I know Quicktime can have transparency and when we create a Quicktime in After Effects and try to import it into Flash, the Keying shows and there is no alpha.

Is there a way to do it?

How did Macromedia do it on the Contribute Flash on their homepage?

Thank you very much for your help.

Sincerely,
Kevin McGlone
