The Intensity Pro card will not be suitable. It does not have simultaneous HD and SD output. You're better off with the DeckLink Studio card instead.
The card will majority of the codecs supported by Final Cut Pro such as DVCPRO HD, ProRes, IMX, XDCAM, Uncompressed etc.
We don't expose a BMD codec in FCP as we use the ones provided by Apple but if you use After Effects, you'll see our Uncompressed codec as an option. That's because we do chroma filtering in our codec when you render so you get a much nicer image.
