Well, I'm about out of ideas on this one. Given that the program SDI out from the Web Presenter is ok, it seems like there's some kind of problem with color handling when compressing the signal to send over USB to the computer.
Now why this would be different between SDI or HDMI, I'm not really sure. Ordinarily I'd suggest that it could be some difference between color depth (8-bit vs. 10-bit) or chroma subsampling (4:4:4 vs. 4:2:2, etc.) on the output. But I think the FS7 is supposed output 10-bit 4:2:2 over both HDMI and SDI.
If the HDMI input into the Web Presenter is ok, I suppose you could run SDI output from the camera into an SDI to HDMI Micro Converter, then HDMI into the Web Presenter. Not ideal, but might be one workaround.
