Hi Matte, thanks for your fast reply.
Please, let me point out a few things, and tell me if I am wrong.

First,
I have to make sure that no levels in my graphics (that i want to appear on screen)
are under about … (10-12% above true “black”),
so 7.5 + 10-12 =… let’s say about 18-20 IRE… right?
Q: I am getting confuse with what you’ve call here -true black- , and I will assume it is a 7.5 legal black. Tell me if not.

Then,
everything i want transparent must be on my waveform at 0 IRe = Zero Black

thanks for any futher and past post.
