10 bit Still Image Export???

I would like to export 10 bit still images from FCP HD, but haven't been able to do so. I set my options in TIFF to support NO compressions and millions of colors +, and the images are only 8 bit. I'm either doing something wrong, or I'm only capturing 8 bits. When I view my clip properties in FCP, it shows that my compressor is the Aurora 10 bit Extreme UC. If anyone has an idea of what I might need to check, I appreciate any and all help.

QuickTime currently is only able to transform movies to 8bit images, which actually is "Millions of Colors". And TIFFs can only be 256 colors, Millions and Trillions.
A possible solution would involve AfterEffects:
Set AE project to 16 bit rendering, drop clip in browser, create new sequence from it and export as SuperTIFF (see below) image sequence with "Trillions of Colors".
SuperTIFF - free AfterEffects TIFF format replacement plugin (faster, better).

You end up with one (or more :) TIFF images containing the 10 bit information from the movie clip wrapped in an 16 bit file.

Hope this helps, Oliver
