Ralph's pastor wants a camera to use to post videos and teach at church. Leo says that most point and shoot cameras take great video, but what he'll want to be sure he gets a camera that can support an external microphone so he'll sound better. Then he can plug in a lavalier mic.
Alex has been watching a lot of live videos on Facebook. He knows that a lot of these are used with mobile phones, but the sound is terrible. He's a musician and he wants to do live performances with Facebook Live. How can he improve the sound?
