Below you'll find the original logs for the color bar test.
The dpx file is number 75 from this image sequence in this zip file (image
sequence zip file<https://drive.google.com/file/d/0B9hzJJkCcuUrMmdHdmFodHFiVjQ/edit?usp=sharing>
).
I hope this is clear enough. Thank you Carl and Lou for pointing this out.
Now I lets get back to the main topic: Is ffmpeg's mxf and waveform output
color accurate?
