Convert to ProRes from DNxHD 709 .

What steps will reproduce the problem?

1.Convert to ProRes from DNxHD movie.

What is the expected output? What do you see instead?

The source DNxHD movie file is output in AfterEffects.
If set the RGB and 709 at Color Levels, the result is different.
I think the result of RGB output is correct.
I hope that the results will match the output of RGB and 709.

What version of the product are you using? On what operating system?
FFmbc 0.7-rc7, win32

- Full commandline run (with -v 3) and everything the program printed
without
the repeating parts.
