Last live stream went well, but there were room for improvement. What should you use? So I have invested in more gear, a USB PCIE card for more video bandwidth to my gaming rig, another Elgato Cam Link 4K go use with my cameras. Will be dropping the iPhone 7 from the setup, running my Panasonic camcorder and 2 GoPro’s instead. A Hero 6 and a Hero 9. One of them using HDMI the other GoPro as a webcam using USB.
