I've searched around online for this for a while now, but am coming up empty. It seems that DVD Studio Pro 2 introduced alpha transitions on DVD's. I'm looking to use Encore, but I cannot find the same functionality.
I know that typically between menus (say, Main Menu and Special Features), your transition clip will need to have a header of the menu and a tail of the submenu. Is there any way to do this with alphas, so that a motion menu will not be disrupted?
