It's the only one that's been around but here's the thing. All this can be very hard on folk as their host PC much be spot on perfect. Also the HDCP can create issues. You told us a camera but no model number and make. What if it's HDMI signal had it's HDCP enabled?
I'm going to buy a video capture card and doing some research on the internet and amazon. Then I came across blackmagic, elgato and magewell. The signal I am going to capture is HDMI from Camera. Any suggestions about the three brand?
