I'm looking for a vid cap device to run Omniscope. Ideally it would be small, cheap, and 12G SDI. It would pass up to 4k 29.997, 59.94, 60 fps. I tried a dongle from Amazon but it did not seem to like 29.97. HDMI is workable with an upstream SDI/HDMI converter, but I am concerned about delay when banging through cameras on a QC router

I had asked that an order be delayed because I had some remaining Tirz. The order was shipped anyway. Now FedEx is delaying delivery. There is no phone number to get customer service. Does anyone have any contact info other than waiting for chat for up to 24 hours?
