What does XSplit Broadcaster do?

It allows you to create scenes and place lower thirds, video sources, audio sources, music, powerpoint presentations, etc. It's designed to give your stream a "Tv show" look and feel. You have several plugins you can use to share on your stream like chat, whiteboard, etc. You can alternate scenes with elegant transitions and you can also broadcast to several places like youtube, facebook and instagram (IG with the help of Yellow Duck). I place 2 or more cameras, 2 or more microphones, I can isolate a single mic, I can adjust audio on the fly and also fix things on scenes or create new scenes if anything comes up, like a live tv show.
