Question: When recording a video, sometimes it's preferable to blur the background, especially when working from home or outside the typical office environment.

I didn't figure out [how to blur the background of a photo booth video recording](https://apple.stackexchange.com/q/412180/290197), so I record without blurring the background. But blurring the background usually makes videos look much more professional. Example:

What is the quickest and easiest way to record a video from a mac webcam that blurs the background? (preferably using software that comes with macOS, but if not, something free and very light weight is preferred)

Answer: 
The easiest approach to attain your goal is to use a video calling application in combination with screen recording.

For the video calling application I suggest [Jitsi](https://jitsi.org/) as it works in your browser, but you can also look into any other popular application like Teams, Zoom or Skype.

1. Go to [meet.jitsi.com](https://meet.jit.si) to start a video call in your browser. For other applications follow the steps they need to start a video call.
2. Configure the calling application to use your camera and microphone.
3. Configure background blurring.
	* In Jitsi you can go to the three dot menu in the lower right and select "Blur my background [BETA]".
	* Here are instructions for other applications: [Teams](https://support.microsoft.com/en-us/office/change-your-background-for-a-teams-meeting-f77a2381-443a-499d-825e-509a140f4780), [Zoom](https://support.zoom.us/hc/en-us/articles/210707503-Virtual-Background), [Skype](https://www.skype.com/en/blogs/2019-02-background-blur/)
4. Now you should have a screen, showing live what is being recorded by your camera.
5. Open Quicktime, and follow [these steps](https://support.apple.com/guide/quicktime-player/record-your-screen-qtp97b08e666/mac) to record your screen, in particular the window of your video calling application.

This will generate a recording of your screen, and as that screen shows your webcam with a blurred background you will have a video of yourself with a blurred background.

Note that some video calling applications have a built in recording option, allowing you to skip step 5.
There is an app for Mac and Windows called ChromaCam.
It has minimum requirements such as MacOs 10.14 but it can accomplish this as well.
