Give them what they asked for but I am sure they can handle both.
It is likely they are loading your file into FCP and using a Kona Card (or similar) to send to the deck.
If it can be handled in FCP,,,you will be golden.
Do both files and let them choose and also...you can check it out.
yeah i know, I've rendered both samples, and compared at 400%. Although the "qt None" seemed better, I still didn't understand this YUV .
I never know if it's a no no to use it if you're already in rgb color space or it's better. I worry that just because I can't see any real difference up close, it doesn't mean it's the better choice for down res to beta.
I use it for Broadcast. No problems.
As a general rule, the less conversion you have to perform on piece of video, the better.
If you already have RGB media, stay that way until you can't.
