  Alpha Key output…

  Posted by Tim Baker on January 12, 2010 at 5:50 pm

  Ok…so I finally got a pseudo animation to test with and when I bring it into FCP…I get no alpha even though the check box is checked in PA…and I put over a hard black background…any ideas on this one?

  Hi guys,

  We resolved this issue, but in case anyone is running into the same issue, be sure that you do not use a compression type such as DVC, HDV, MPEG, JPEG or any other that does NOT support an alpha channel. If you are rendering to a QuickTime movie, the compressor must be set to “Animation” and “Millions of Colors+”. The “+” means it will render with the Alpha Channel. If you render out in AVI format, use the Uncompressed option.

  Best,
  Edward
