No Voice Recording for Incoming Video on QuickTime On Mac I have used Quicktime player on Macbook Air to record a Google Hangout video. I have noticed that it doesn't record the voice but only video. I am wondering if there are any settings that I am missing to make sure the audio also works with QuickTime. 

If there are no settings, then I am thinking to record the video and audio in my iPhone voice memo together . Then is there a way to add the audio in the video recorder by QuickTime? 

My options :
In this case you can't capture 2 recordings simultaneously with Quicktime. You have use additional Apps e.g Garage Band, Audacity, Audio Hijack or a iPhone to record your internal audio. 

In previous Quicktime Pro Versions it was possible insert a audio sequence to a Quicktime Movie.

Here’s a quick how-to:


Open Apple iMovie
Import your Google Hangout Video Screen Capture 
Add your audio recording to your iMovie project.
Export your Video
