Here's the comparison, I used all defaults and for beta 6 and 7 I used chroma_process=0. I like beta5 better.

Also, do you think it would be worthwhile to have U=xx, V=xx parameters instead of chroma_process=xx? I've come across footage where one of the chroma channels seems to be more "saturated" than the other.
Maybe independent parameters can aid those types of situations.

One last thing, AutoGain works fine with 8bit YV16/24 and with 16bit YV12 but with 16bit YV16/24 I get some weird artifacts which seems to only affect the MSB/top half. Here's an example after dithering to 8bit.


Kudos on the debug view. It looks very good!
Thanks again for all your awesome work!
I made a mistake with dark_exclude/bright_exclude, default should be "0.5" and not "0.05"... I will change it in next version, for now use "dark_exclude=0.5,bright_exclude=0.5".

And for 16bits / YV24, this seems a chroma bug (maybe I forgot a shift somewhere... )
