Hello. I'm totally new, and I think I have everything set up properly. My plan is to stream on YouTube today with a prerecorded short video on loop. I just want to make sure I know what to do and not do with my computer and screen when it's going. Do I need to keep my windows open and volume on? Can I do other things on the computer at the same time and just stream the uploaded video with it's audio? Thank you. Tonya
