M1 iPad Pro: Camo Studio PiP recording, external cam, audio

Hi, I hope You are having a good day

I want to buy a M1 iPad Pro, but since I don’t have any access to iPad before purchasing, I want to make sure if “Camo studio” app can fulfill my needs. I’m a YouTube reactor and I want to record realtime YouTube app (while im watching Youtube) and my picture from an external camera and external Mic in PiP mode so I have two questions:

1. Can This app on M1 iPad Pro record YouTube and my external camera feed at the same time in the background without any lagging while I’m watching YouTube ?

2. Is there any setting on the Camo Studio app which I can control my external Mic level and original Youtube sound independently so I can increase or decrease each one separately ?

Thank you so much in advance for helping me. 🙏🙏
