Light weight, free way to record a video with a blurred background using Mac webcam?
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 as it works in your browser, but you can also look into any other popular application like Teams, Zoom or Skype.
- Go to meet.jitsi.com to start a video call in your browser. For other applications follow the steps they need to start a video call.
- Configure the calling application to use your camera and microphone.
- 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, Zoom, Skype
- Now you should have a screen, showing live what is being recorded by your camera.
- Open Quicktime, and follow these steps 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.
