[FFmpeg-user] Prores 444 being detected by quicktime as 422?

I seem to be unable to generate a 444 prores .mov file that quicktime 
player will indentify as 444. QT Player claims the movie is 422.

Several misc. sources (one of which is 
http://transcoding.wordpress.com/2012/01/29/prores-ffmpeg/) quote 
examples of using the arg "-pix_fmt yuv444p10le" to generate 444 prores 
quicktime movies. However, whenever I use yuv444p10 or yuv444p10le 
ffmpeg presents the error:

Incompatible pixel format 'yuv444p10le' for codec 'prores', 
auto-selecting format 'yuv422p10le'

I have tried various source qt movies of 8 bit uncompressed, 10 bit 
uncompressed, 422 prores and 444 prores. The output movie is created, 
but is always 422 (in Quicktime Player) and ffmpeg displays the 
"imcompatible pixel format" message.

I have been told that ffmprobe identifies the file as 444, but quicktime 
player identifies the output files as 422.

I am using an ffmpeg win32 static build on Windows 7, 64-bit OS.

CommandLine:
ffmpeg-20120903-git-5d55830-win64-static\bin\ffmpeg.exe" -i 
"C:\Server\Jobs\Conversion\FlameOutput_Quicktimes\Car_10BitRGBUncompressedTC.mov" 
-vcodec prores -profile 3 -pix_fmt yuv444p10le -f mov 
"C:\Server\Jobs\Conversion\FlameOutput_Quicktimes\Car_10BitRGBUncompressedTC\Car_10BitRGBUncompressedTC.mov"
