Using Quicktime Player to Screen Record with Audio?

Record a screen video with sound

To capture the output sound you need to install third-party software. I recommend the tool Background Music. To install either

• Use Homebrew, open a new Terminal window and run: brew install --cask background-music
• Or download from the GitHub repository at https://github.com/kyleneideck/BackgroundMusic and install the .pkg file.

After installation, in Screen Recording you will see an option for Mikrophone called Background Music. If you choose this option, the screen recording will also capture the System output audio.

Choose Background Music as Microphone in the Options menu to record System output audio.

Hello mikehende,

This may occur if you've downloaded third-party apps and changed your settings.

According to the resource you mentioned: How to record the screen on your Mac

Use QuickTime Player

1. Open QuickTime Player from your Applications folder, then choose File > New Screen Recording from the menu bar. 

- If you see the onscreen controls described above, follow those steps.

- If you see the Screen Recording window described below, follow those steps.

2. Before starting your recording, you can click the arrow next to the Record button  to change the recording settings:

- To record your voice or other audio with the screen recording, choose a microphone. To monitor that audio during recording, adjust the volume slider. If you get audio feedback, lower the volume or use headphones with a microphone.

- To show a black circle around your pointer when you click, choose Show Mouse Clicks in Recording.

3. To start recording, click the Record button  and then take one of these actions:

- Click anywhere on the screen to begin recording the entire screen.

- Or drag to select an area to record, then click Start Recording within that area.

4. To stop recording, click the Stop button  in the menu bar, or press Command-Control-Esc (Escape).

5. After you stop recording, QuickTime Player automatically opens the recording. You can now play, edit, or share the recording.

We underlined the important information. Recording your screen may not work with some apps or windows. And you'd need to adjust your volume on the Mac in order to record the audio along with the screen recording or we'd suggest using headphones. Keep in mind, you may need to remove the third-party apps you installed and restart the Mac normally in order for these steps to work successfully.

Let us know if this helps out, take care.

Only the viewing size can change, actual video recording size is limited by the Camera, but could be post processed to other sizes.

Great work! :)

Take care my friend! :

Great news my friend & yes, I highlighted the wrong option.

The .mov will be the size that the Camera ca actually record at, but viewing window can grow or shrink with CMD&+ or CMD&-
