Problems switching bit depth in input file

[electron.rotoscope]

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

% ffmpeg.exe -i D:\cartest_supers.mov -pix_fmt yuv420p -vcodec libx264 -crf 24 -an D:\outvid.mp4

I don't know if this pastebin is any different but it's -v 9 -loglevel 99 ​http://pastebin.com/Mg3VSEws

Regression since 64e7cf12 - should be fixed in dcac15a8
Thank you for the report!

For future tickets: Please do not use external resources (like pastebin), always post all necessary information here on the bug tracker. Please do not upload output files, this nearly always leads to confusion, just write that the issue is a regression (worked with version xyz).

I'll keep that in mind, thank you! Wow this will really help, I wish I'd reported it sooner!
I actually didn't know that it ever worked properly, I've never tried it in an ffmpeg that didn't have an error at the switchover point.
