It is kind of funny that you are asking me the best way to see my Livestream recording as I’m recording it. I am sitting here with an iPhone and an IPad and I am having issues with the camera. So it’s funny that I am giving advice. To be honest, I use a software program called OBS. It is free and you can use it with an external camera. Or, you can use a webcam and a microphone on your computer. I have tried another software called Wirecut, but I never did figure it out, so I do not recommend that one.  I am sure there are other programs and other people who understand them, but OBS does the job and it doesn’t cost anything so that’s what I use.
