How to Remove Background in OBS?

With OBS Studio, there are multiple ways to achieve this—ranging from green screens to OBS background removal plugins and software-based solutions. In this guide, we’ll explore these methods in detail. We’ll walk you through the steps for removing the background with a green screen for a clean, crisp result, as well as using OBS background removal without a green screen via powerful plugins. Along the way, we’ll share practical tips for optimal background removal and help you decide which approach suits your needs best.

How to Remove Background Using a Green Screen in OBS?

One of the most effective and reliable ways to achieve clean background removal is by using a green screen. Green screens help OBS differentiate the subject (you) from the background, ensuring a crisp, professional look. This technique is widely used by streamers, content creators, and video professionals because it provides superior precision compared to software-based solutions. With OBS’s Chroma Key filter, the green background can be removed smoothly, leaving you with a transparent or replaced background of your choice.

Step-by-Step Guide: Removing Background with a Green Screen

Here is an elaborate step-by-step guide to help you get up and running with removing the background screen in OBS with a green screen. 

1. Set Up the Green Screen

• Position the green screen properly: Ensure that the screen covers the entire area behind you so no part of the original background peeks through.
• Remove wrinkles or creases: These can create shadows and inconsistencies, disrupting the chroma keying process. Using a stand or tension frame can help keep the screen taut.
• Ensure consistent lighting: Uneven lighting can cause dark spots or color variations that interfere with the Chroma Key filter. Use multiple lights if possible to illuminate both yourself and the green screen evenly, reducing shadows.

2. Open OBS Studio and Configure the Scene

• Add a new scene or use an existing one: Go to the Scenes panel in OBS and create a new scene if you don’t have one set up already.
• Add a video source: Click the + icon under the “Sources” panel and select your webcam or camera device.
• Access the Filters menu: Right-click your video source and select Filters to open the filters panel, where you will apply the background removal effect.

3. Add the Chroma Key Filter

• Click the + icon under Effect Filters: In the Filters menu, select Chroma Key from the list of available effects.
• Name your filter: You can give it a custom name (e.g., "Green Screen Removal") to help you manage filters easily.
• OBS will detect the green color by default: The software automatically applies a standard keying effect to remove the green background. If your background isn’t removed perfectly on the first try, don’t worry—you can fine-tune it in the next step.

4. Fine-Tune Chroma Key Settings

• Similarity: Adjust this slider to define how close the color must be to the green key color to be removed. Increasing the similarity removes more background, but setting it too high can affect parts of your clothes or face if they have green hues.
• Smoothness: Use this setting to soften the edges of your subject and reduce harsh lines that might appear around your figure. However, be cautious, as too much smoothness can blur your outline.
• Key Color Spill Reduction: This feature helps reduce green light reflections (spill) on your skin or clothing. If you notice a green tint around the edges, increase this setting to minimize it.
• Custom Key Color (Optional): If your green screen isn’t a perfect green, you can manually select the shade of green being used by clicking on the Key Color option.

5. Test the Output and Adjust Settings as Needed

• Check the live feed: Ensure that the background is removed cleanly and that no artifacts or shadows remain. Move around to verify that the Chroma Key filter consistently maintains transparency without cutting off parts of your image.
• Make further adjustments if needed: If you notice flickering or incomplete background removal, return to the Chroma Key settings and tweak the sliders until the results improve. Test under different lighting conditions to ensure consistency.

6. Save Your Settings

• Once you are satisfied with the results, click Close to apply the changes. OBS will save the configuration automatically, and your green screen background removal is now active for the selected scene.

Now, let’s take a step forward and understand how to remove OBS background using plugins, without using any green screen.
