The “Similarity” setting seems to make the most difference for me.

Adjust the settings until the background is all grey, and you still look clear.

The default “Green” option worked for me. It will also allow you to set a specific colour using a colour picker from the background.

Select the background colour under the “Key Color Type”.

Pick the “Chroma Key” option, and on the subsequent dialog click the “OK” button.

Click the “+” under the “Effect Filters” panel.

Right-click on your Source (WebCam) and select the “Filters” option from the popup menu.

Click “OK”, and your camera will be in the “Sources” list.

If you have multiple cameras connected, select your camera in the “Device” dropdown. Using all the powers of my imagination, I decided on “WebCam”.

Type in the name you want for your device.

Pick “Video Capture Device” from the popup menu.

This post contains some quick notes to get you up and running if you want to try it.

I finally took the plunge and ordered a green screen, but how do you go about using it? Fortunately Samuel Nitsche mentioned Open Broadcaster Software (OBS) Studio, so like the obedient sheep that I am, I gave it a go. 😱 That’s a bit of a problem if your washing is permanently on display in the background. I’m not sure if you know this, but a lot of people are using video conferencing, and not all video conference tools allow you to use virtual backgrounds.
