Using BMCC with ATEM Switcher

I am very interested in using the BMCC camera with my ATEM switchers for live production. I just tested my BMCC with my ATEM Studio, using a BM up/down/cross converter. I was able to get it working for both 720p 50 & 59.94. The up/down/cross converter does not seem to support a conversion to 1080i.
