In Snagit 2018, the movie option is now recording sound from my mic in addition to the sound from the video. How do I record only the system audio? In earlier versions, only the system audio was recorded. I'm sure this is a nice feature for screen caps, but there must be a way to only select system audio. I'm sure I could turn off the mic sound level in system preferences, but there must be a way to choose audio sources in SnagIt.
