 Some editing systems such as Avid Media Composer will routinely create
 quicktime files that have some frames yuv422p and some frames yuv422p10le
 in the same file. When ffmpeg tries to encode video from these files it
 creates different glitches depending on unknown factors, but usually the
 result is not clean video.
 Sample source file with on-screen text showing the changing bit depth
 available at http://electronrotoscope.com/ffmpeg/cartest_supers.mov and
 without onscreen text at
 % ffmpeg.exe -i D:\cartest_supers.mov -pix_fmt yuv420p -vcodec libx264
 -crf 24 -an D:\outvid.mp4
