Hi Walter,
thank you for your reply!

[Walter Soyka] “If you’re inputting ARRI LogC3 Wide Color Gamut -EI800, and if you’re outputting ARRI LogC3 Wide Color Gamut -EI800, why work in Rec. 709? “

I work in Rec. 709 because is the color space of the delivery (TV series). Is that correct or am I doing something wrong?

[Walter Soyka] “Rather than using Curves and manually adjusting the green channel, you might consider using a Levels effect. Leave the defaults untouched, but set “Clip to Output White” to “On.””

I try using Levels and this is what I get. You can see the effect in the pictures before and after applying it. It gets rid of the green but then a blue halo appears. So I then assume I can’t use After effects working with 32 bpc and log files? It’s a pity!

I’ve found the problem when I’m not using any exposure control. If use it, the result is the following, which is what I wanted.

Thankyou Dave,

There’s no problem with this particular shot, I only use it an example of how green the green gets (if this makes any sense) In fact, in the picture attached, the Advanced spill suppressor is only affecting the left corners of the TV.
My concern was more related to the workflow / way to work than this shot.
