Roger may be "intermingling" knowledge of a thread on ffmpeg zeranoe 
(http://ffmpeg.zeranoe.com/forum/viewtopic.php?f=7&t=707&sid=3274fe1a5efcc0021653f967447f9057) 
and this thread but he is correct.
It may be hard to believe but every quicktime that I have tried to 
convert in ffmpeg using yuv444p10le and prores or prores_kostya results 
in a prores quicktime that ffmpeg indentifies as 444 yet is identified 
as 422 by quicktime player.

Carl is the first person to suggest that ffmpeg cannot create yuv444 
(which helps the mystery a bit).
