How to Blur Your Webcam Background in OBS

The short answer

OBS Studio has not traditionally included a one-click background blur. The usual method is to add a background removal plugin, apply its filter to your webcam source, and turn on its blur option. That plugin uses person segmentation, meaning software that estimates which pixels are you and which are the room. If you want the blurred image in Zoom, Teams, Meet or a similar app, start the OBS Virtual Camera and choose it as the camera in that app.

There are two other routes. Some webcam utilities, graphics-card tools and operating-system camera effects blur the image before it reaches OBS, so OBS receives video that is already blurred. Many call apps also have their own blur. If you only need blur in a single call app and don't use OBS for anything else, that app's built-in setting is the simpler choice. OBS is worth the extra steps when you want the same blurred, adjusted image in several apps, or when you are also using overlays, scenes or recording.

Every one of these methods is a virtual video effect. It is not the same as a physically blurred background from lens depth of field, and it is not the same as blurring a background in a photo editor afterward.

Before you start

• A recent version of OBS Studio installed from the official OBS project.
• A background removal plugin release that matches your OBS version and operating system. Plugins are built for specific OBS versions, so check the plugin's release notes before you install it.
• Camera permission for OBS. On macOS, OBS must be allowed under System Settings > Privacy & Security > Camera. On Windows, check Settings > Privacy & security > Camera, including access for desktop apps.
• No other app holding the camera. On many systems, especially Windows, only one app can use a webcam at a time. Close call apps and camera utilities while you set up OBS.
• Even, front-facing light if you can manage it. Segmentation works best when you stand out clearly from the background.

This guide cannot give verified hardware requirements, recommended blur values or performance thresholds, because none were available for it. Use the plugin's own documentation for supported systems and GPU or CPU requirements.

Step 1: Get a live webcam image in OBS

• In the Sources panel, click the + button and choose Video Capture Device. On Linux it may be listed as Video Capture Device (V4L2).
• Name the source, then select your webcam from the Device list.
• Resize or position the image in the preview as needed.

Success check: the preview shows live, moving video from the correct camera. This confirms that OBS has camera access and is capturing video. Those are separate things. A source can show up in the list and still produce a black image if permission is missing or another app is using the camera. Fix that before adding any effects.

Step 2: Install the background removal plugin

• Close OBS.
• Download the plugin installer or package for your operating system from the plugin's official release page.
• Run the installer, or follow the plugin's manual install instructions for your platform.
• Reopen OBS.

Success check: right-click your webcam source and choose Filters. Click + under Effect Filters. A background removal entry should now appear in the list. If it doesn't, the plugin most likely doesn't match your OBS version or wasn't installed to the right folder.

Step 3: Add the filter and switch it to blur

• In the webcam source's Filters window, add the background removal filter under Effect Filters.
• In the filter's settings, find the background blur control and raise it above zero. When blur is off, the plugin typically replaces the background with a solid color or transparency, not a blur.
• If there is a choice of processing device, such as CPU or a GPU option, try the GPU option first if your system supports it, and switch if the preview stutters.
• Adjust any threshold, smoothing or edge settings until the outline around your head, hair and shoulders looks natural.

Success check: in the OBS preview, the room behind you is blurred and you stay sharp. Wave a hand, turn your head and lean back. The blur should follow you without large patches of background showing through or parts of you being blurred away.

Step 4: Check that your computer can keep up

Segmentation runs on every frame, so it adds processing load. Open the Stats dock from the View menu under Docks. Watch it for a minute while you move around in front of the camera. Steadily rising counts of skipped or lagged frames mean the effect is too heavy for your current settings.

To reduce the load, lower the base and output resolution or the frame rate under Settings > Video. You can also use the plugin's GPU option or a lighter model if it offers one, and close other demanding apps.

Step 5: Use the blurred feed in a video call

• Make sure the scene with your blurred webcam is the active scene in OBS.
• Click Start Virtual Camera in the Controls panel.
• Open your call app. In its video or camera settings, select OBS Virtual Camera.
• Turn off the call app's own background blur or replacement so you aren't stacking two effects.

Success check: the call app's self-view shows the same blurred image as the OBS preview. If OBS Virtual Camera isn't listed, start the virtual camera first and then fully restart the call app. On macOS, the first time you use the OBS virtual camera you may be asked to approve a system extension. Browser-based call apps also need camera permission for that site.

Some call apps mirror your self-view. Text in your scene may look reversed to you while appearing correctly to others.

What this check tells you, and what it doesn't

A good OBS preview and a correct self-view tell you three things: the camera is captured, the blur is applied, and the call app is receiving the virtual camera. They don't tell you how the image looks once the call service compresses it for other participants, how it holds up on a slow connection, or how the edges behave in different lighting later in the day. To check those, do a short test call with another person or a second device, and ask them to watch your edges while you move.

If the result looks wrong

Problem | Likely cause | What to try

Black or frozen preview | Camera permission missing, or another app is using the camera | Grant camera access to OBS, close other camera apps, then reselect the device in the source properties

Background is a solid color instead of blurred | Blur amount set to zero | Raise the blur setting in the filter properties

Flickering or ragged edges, hair disappearing | Low contrast between you and the background, or dim light | Add front light, move away from busy or similarly colored backgrounds, adjust smoothing or threshold settings

Choppy video or rising skipped frames | Processing load too high | Use the GPU option, lower OBS resolution or frame rate, close other heavy apps

OBS Virtual Camera missing in the call app | Virtual camera not started, or app opened before it started | Start the virtual camera, then restart the call app; on macOS, approve the extension if asked

Call shows your raw camera, not the blur | Call app still set to the physical webcam | Select OBS Virtual Camera in the call app's video settings

If segmentation still struggles, reduce what it has to work with. Sitting a bit farther from a plain wall, or putting distance between yourself and anything cluttered behind you, often makes the edges cleaner than any settings change.
