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.
Can he connect it to a laptop and record directly to the PC? Leo says he can, sure. But cameras have to support it through live HDMI out. That probably means getting a camcorder like the Canon Vixia. For audio, Leo says the Shure Motiv is a really good mic. The Blue Raspberry is quite good as well. Leo recommends avoiding the Blue Yeti, though.
