I am using unmult in conjunction with a lens flair in order to generate a proper alpha channel. Unfortunately when I attempt to export the file as AVI Matrox Uncompressed HD + Alpha, the option for export Alpha and RGB is greyed out. As soon as I delete the unmult the RGB + Alpha becomes active again
Matrox Mpeg 2 I frame works but the the Matrox Uncompressed does not.
Anyone with the same issue? Is there something I am doing wrong
