I have the same basic problem. We shot a talking head in front of green, made QuickTime clips in Media Composer and sent the QT file to the Flash designer to integrate into a project. He asked if it was compressed with the alpha channel. Doing a little digging, I find that no, it was not compressed with the Alpha Chanel ( or ever will be I guess) Should I Export the “Show Matte” of the same sequence as a quick time, and ftp him that in addition so that he can do the composite? Thanks!
