# Remove Background in OBS Studio (No Green Screen)

> Source: [Remove Background in OBS Studio (No Green Screen)](https://youtube.com/watch?v=6du8CImc5Ik)

## Summary

This tutorial demonstrates how to remove your webcam background in OBS Studio without a physical green screen. It uses the free Prism Lens app to simulate a green background, then a standard Chroma Key filter in OBS to make it transparent. The result is a clean webcam overlay that can be layered over gameplay.

### Key Points

- **Install and set up Prism Lens** [00:01] — Download Prism Lens from prism.live.com, select a Prism Lens, and choose your webcam as the video source.
- **Create a virtual green screen** [00:14] — Search Google for a 1920x1080 green screen image, then in the Prism Lens app go to the My tab, tap the plus icon, select the downloaded image, and open it.
- **Add Prism Lens to OBS** [00:30] — In OBS, add a Video Capture Device source and select the corresponding lens (e.g., Prism Lens 1) that you configured.
- **Apply Chroma Key filter** [00:43] — With the source selected, open Filters, add a Chroma Key filter, and adjust until the green screen is removed.
- **Finalize the layout** [00:56] — Close the filter window, readjust your webcam positioning, and place your gameplay source behind the webcam layer.

### Conclusion

By combining a virtual green screen image in Prism Lens with OBS's Chroma Key filter, you can achieve a broadcast-quality background removal setup without purchasing any physical equipment.
