I'm trying to get animation composer to recognize something other than my webcam on my monitor. Is there something I can do to get the app to recognize another camera that's connected to my computer? Do I need Blackmagic Ultrastudio or something similar to get the app to see it? Any help on this issue would be much appreciated.
On the Camera and Microphone panel, hit the hamburger menu, and click on "Switch To Next Camera"
Yep, as Ben says above - that's the way. If that doesn't work for you then it's possible the camera you're trying to use isn't a webcam (DSLRs, iPhones, etc won't work), or maybe a driver update issue? Let us know if the problem persists.
