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
http://electronrotoscope.com/ffmpeg/cartest_clean.mov
{{{
