If you Proc the video to 7.5IRE your black level will be at 15 IRE when it hits the air.
We produce everything with digital 0 black.
You can not compensate for the DG added black with just lowering your black level, or as they said in he old days “Crushing the Blacks”.
We found we had to adjust three levels with the FinalCut Proc filter to compensate.
Setup = -0.25, Video = -0.38 and Chroma = +1.05
It is not perfect, but it is much better than no compensating.
