Preserving Alpha Channel when converting AVI to FLV for Storyline

Hi all,
I need some help. I am trying to render out a chromakeyed video (rendering avi uncompressed 32bit) that I need to convert to FLV to work in an Articulate Storyline e-Learning project.

The problem I'm having is that when I render out from Sony Vegas Pro 12 and then convert the AVI to FLV(using Adobe Media Encoder CS6), the alpha channel doesn't seem to be preserved when I bring it into Storyline.

Any ideas on what the right workflow is? Any help is much appreciated.

Thanks.

Update...I have been intsructed to render the video out of Vegas as a png image sequence; which I have done successfully.  Now the problem is that the transparency isn't preserved when I convert the png image sequence to a flv file using Adobe Media Encoder. 

Any ideas and/or experience with this workflow would be appeciated.  Thanks.
