Thanks for confirming what I thought. I will drill down into those settings later, the main thing is facing the fact I will have to render twice. I accept that fate in the interest of quality. I wonder what is the path to 'the movies?' I don't mean the odd digital projector now beginning to appear in movie theaters in major cities, I mean if you create this great digital movie, what is the optimal quality path to 'film?' ::::: Opera :::::
