To use external camera support on the Proto Studio app, you must use an iPad Pro or above running iPadOS17 or higher.
After you have confirmed you have the correct iPad, proceed with mounting your DSLR camera in portrait mode on a tripod approximately 2.5 feet off the ground, 10–12 feet away from the individual being Live Beamed.
Connect the camera's HDMI or SDI output to your USB capture card. Then connect the capture card to your iPad Pro using a USB-C cable or adapter.
Once you have all the components connected, navigate to Beam Settings in the Proto Studio app and select the correct camera input and audio input (if you have mic routing through the capture card as well).
