  exporting transparency for FCP Pro6

  Posted by Laura Gruszczynski on February 18, 2008 at 9:02 pm

  Hi,
  I am trying to export comps from After Effects CS3 with alpha channels to use in FCP, I find that some codecs do not show the transparency in FCP 6 even though I exported them with RGB and Alpha, straight matted.
  The animation Codec works fine but I have to compress the piece again for the web and I don’t want too much compression before I do that. AJA Kona’s setting allow me to export with RGB and Alpha straight but shows a black background in FCP.
  Any ideas?
  Thanks, Laura

  My apologies, yes, I meant render.
  I set my settings to the aja kona 10 bit, which did allow me to select RGB and alpha, straight matted, and hit render. I imported it into FCP, and the background is black, even when I change the alpha in the browser window to “straight.”
  Not sure what I am doing wrong.
  Thanks, Laura

  I have never used anything except the Animation codec for transparency. It is the only codec I know of that actually holds alpha. Lots of codecs will offer the option in the setting box but the codec itself still cannot transfer alpha. Dunno why QT let’s you think you can use an alpha with a codec that can’t.

  Coming out of FCP using Animation is tricky because of the silly way Apple has set up the export function. You must first un-render everything before you try to export using Animation. It makes sense after you think it through but it’s still stupid. The application should be able to figure it out.

  This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”
