I will record a video for you then Alex because mine locks up big time...

Still couldn't reproduce, and I'd like to know what's going on before merging this.

Is this still being tested or is it merged already?
Sometimes you have to go out on a limb to get the fruit.

N/A

7d in 60p mode (720 or 480) display gets the wrong black level when fps override is set to 60 and mlv or raw rec are on. I'll upload examples and run the black level console when I get home.

Console was reporting black level of 2077 or 2080 iirc.

The black level issue in this thread, is in regards to the black level value saved in the exif info.  An incorrect value will produce color casts in the image.

Your noise issue is due to the exposure being 2 stops underexposed.

The black level fix has been merged with unified and is now in the nightly builds.

Thanks to all those that helped.
