All for inputs are via HDMI, 2 Canon HF G10 and 2 PCs. The output will be HDMI to an active HDMI Splitter to TVs and another PC with an Intensity Pro (we’ve had it for a while so no sense purchasing another capture card just for SDI right?). There might be a few HDMI to SDI converters in the mix. I’m not sure if there is a way to genlock HDMI sources.
