Recently purchased for my church the VR-5. First- it's a great product. I have one computer connected for web streaming. I have another computer connected to hopefully insert lower thirds and text. According to the manual the logo or text needs to be on a black or white background then use the key-composting feature. Has anyone been using this feature? Guess I'm doing something wrong. I'd like to get a lower third and insert text into it and put it on the screen when broadcasting. Does anyone already do this and can give me some pointers. Just for information - I'm a true novice at all of this.
