Propresenter has an SDI module for sale as well as a alpha channel module for sale as add on licenses to Propresenter. The most professional and appropriate way to key your graphics is to use an alpha channel. Alpha channels cut the hole, and the fill video fills the hole. So, the hole and fill are always exactly what you want it to be (or at least what you set them to be).
So to do this "right", you'd want to buy those two licenses, and (if you don't already have it) a compatible Decklink product. Then you would run two separate SDI cables to the ATEM, one for the key and one for the fill, and set up the downstream key to have those as your key and fill sources.
One of the great things about key channels (alpha channels) is that you can make semi-transparency through making the key channel not white, but shades of gray.
