There are a ton of new Sony FS-100 owners out here that need some ouput flexibility. With only one HDMI output it pretty limited. I would like to hook up my 7" monitor, external recorder, and client monitor. These devices use a mix of HDMI an HDSDI.
So.... can you make a block that has 1in/2out HDMI and 1in/2out HDSDI with all outputs available at all times. Pick one input and make it go to all 4 outputs.
This is pretty close to what you already have in your Shuttle.
Or make a new shuttle with these i/o's and add a ProRes codec.
