How to Green Screen in OBS

Streamers looking to add a professional touch to their videos can benefit from using a green screen, also known as chroma keying, in their streaming software. One popular software for streamers is OBS (Open Broadcasting Software). Here’s a step-by-step guide to setting up a green screen in OBS.

1. Get a Green Screen Background

First, you’ll need a green screen background. This can be a physical green screen or a green screen background that you’ve created digitally.

2. Add a Video Capture Device in OBS

Next, open OBS and add a new source by clicking the “+” button in the bottom left corner. Select “Video Capture Device” and give it a name, like “Green Screen.”

3. Configure the Camera and Resolution

Under “Device,” select the camera you’ll use for your green screen. In the “Resolution/FPS Type” section, select “Custom” and enter the resolution and frame rate you’ll use for your stream.

4. Preview the Green Screen

Click “OK” and you should now see a preview of your green screen in OBS.

5. Add a Chroma Key Filter

Next, you’ll need to add a filter to remove the green screen from your video. To do this, right-click on the “Green Screen” source and select “Filters.”

6. Adjust the Chroma Key Settings

Click the “+” button and select “Chroma Key” from the list of available filters. In the “Chroma Key” settings, you can adjust the similarity and smoothness of the green screen removal. Play around with these settings until you’re happy with the results.

7. Add More Sources

Once you’ve adjusted the settings, you’ll be able to see your background video through the green screen. You can add more source to make it look more professional.


By following these steps, you’ll be able to easily set up a green screen in OBS and take your stream to the next level. Remember to test your set up before going live, and adjust accordingly for the best results.
