I have just been informed that one of the Networks we are about to broadcast on (Daystar) has set there levels at 7.5 and 78 IRE. We already edit to 7.5 but our top is obviously 100 with a lot of things brought down to around 90. Obviously others are doing this since they air other programs but for me this will be something new.

Anyone have a suggestion for getting there without having everything look crushed?

I am working with AE 6 and AVID MC 7.02. I do a lot of my work in AE so that is critical but my final products are made on the AVID.

I think this would be more of an Avid question than an AE question. With all the Avid settings options, I'll bet there's a way to get the thing to work like a proc amp that limits peak video levels to 78 IRE. You deliver for Daystar, you use that particular setting; otherwise use the default setting for everything else.

Boy, that's a really weird delivery spec. Any clue why they want it that way?

No idea. We were forced to seek another carrier a few weeks back and this was thrown together rather quickly. Still in conversations with them to find out the whats and whys.

I think a lot of it pertains to graphics which is why AE is a critical step for me since all my graphics come out of there.

I've already begun some tests but I can't say that I am all that pleased with the look.
