The original .mov file has the grayscale bit set in the bit depth field 
of the video sample description, but since that seemed highly illogical 
to me, I cleared it for the purposes of this demonstration. For some 
reason, QuickTime in Win or Mac seems to ignore the grayscale bit, since 
it will display the file in blue colors regardless. Perhaps we should do 
the same? This is not documented behaviour, though.
