Mute the microphone during recording

Muting mid-take avoids capturing side conversations without stopping the video.

Steps

1. Start with a microphone enabled if you plan to narrate.
2. When someone enters the room, mute from the floating panel.
3. Unmute when you continue the explanation.
4. After stop, trim any stretch that stayed silent too long.
