I don't know about anyone else, but I kind of liked the auditory feedback so I could tell what was a voiceover and what was part of the actual footage. It made it sound kind of cool... I'm not sure how else to explain it haha
Is ejecting a USB device (or any device, for that matter) necessary? I've never seen a very good tutorial on it and it's not explained very well why or when we should eject our devices.
