Add a webcam source to OBS

The short answer

In OBS Studio, you bring in a webcam by adding a Video Capture Device source to a scene and choosing the camera from its device list. That source handles the picture. The webcam's built-in microphone is a separate step. Depending on your platform and OBS version, you either enable audio inside the Video Capture Device properties or add the microphone as its own Audio Input Capture source. Your speech is captured only when the webcam microphone appears in the Audio Mixer and its level meter moves while you talk.

Two conditions limit this. First, OBS can only use the camera and microphone if the operating system grants it permission. Second, the exact menu labels and options differ between Windows, macOS and Linux and between OBS releases. Treat the paths below as typical, and check them against the version you have installed.

Before you start

• 1. Connect the webcam directly to the computer and confirm the operating system recognizes it as a camera and as a microphone. Many webcams appear as two devices, one for video and one for audio.
• 2. Close other apps that may be holding the camera, such as video-call software or the system camera app. A webcam is often usable by only one application at a time, and OBS may show a blank or black source if another program has it.
• 3. Allow camera and microphone access for OBS in your operating system's privacy settings. On macOS this is under Privacy & Security for both Camera and Microphone. On Windows, check the camera and microphone privacy pages and make sure desktop apps are allowed access.
• 4. Open OBS Studio and select the scene where the webcam should appear, or create a new scene.

Adding the webcam video

• 1. In the Sources panel, click the plus (+) button.
• 2. Choose Video Capture Device. On Linux this may be labeled Video Capture Device (V4L2).
• 3. Select Create new, give the source a recognizable name such as the camera model, and confirm.
• 4. In the properties window, pick your webcam from the Device dropdown. The preview should show the camera image.
• 5. Optionally, set resolution and frame rate. On Windows these appear under a Resolution/FPS Type setting that can be switched from Device Default to Custom. Pick values the webcam lists as supported.
• 6. Click OK, then resize or position the camera in the preview as needed.

Capturing the webcam microphone

Adding the video source does not guarantee that the webcam's microphone is being recorded. Use one of the two approaches below, but not both for the same microphone. Capturing the same mic twice produces doubled audio that can sound phasey or echoey.

Option A: Audio Input Capture source (works across platforms)

• 1. In the Sources panel, click plus (+) and choose Audio Input Capture.
• 2. Create a new source and name it, for example Webcam Mic.
• 3. In the Device dropdown, choose the webcam's microphone. It usually carries the camera's brand or model name.
• 4. Click OK. A new channel with that name should appear in the Audio Mixer.

Option B: Audio within the Video Capture Device (Windows)

• 1. Open the properties of the Video Capture Device source.
• 2. Look for a setting to use a custom audio device, enable it, and select the webcam's microphone.
• 3. Check the Audio Output Mode setting. The option that captures audio, rather than sending it to desktop audio, keeps the mic on the source's own mixer channel.
• 4. Click OK and confirm that the webcam source now has a channel in the Audio Mixer.

Option A keeps the microphone independent of the camera source. You can then mute, filter or adjust it separately, and it keeps working if you hide or swap the video. Option B ties the audio to the camera source, which some people find tidier for a single-camera setup. Both are documented OBS approaches. Which one is available, and how it is labeled, depends on your platform and version.

Also check Settings, then Audio, for the global microphone or auxiliary audio device. If the webcam microphone is already selected there, OBS is capturing it globally, and adding it again as a source would duplicate it. Pick one place to capture it.

Checking that speech is actually being captured

• 1. Speak at a normal volume from your usual seating position and watch the webcam mic's meter in the Audio Mixer. It should rise with your voice and fall back between phrases.
• 2. Confirm the channel is not muted. The speaker icon should not be crossed out, and the fader should not be pulled all the way down.
• 3. Make a short test recording, then play it back and listen for clipping (harsh distortion on loud words), a level too low to follow easily, or doubled sound.
• 4. If lip movement and voice appear out of step in the recording, open Advanced Audio Properties from the Audio Mixer and adjust the sync offset for the webcam mic until they line up.

If the meter does not move, recheck the operating-system microphone permission. Then confirm the correct device is selected, since webcams and headsets can have similar names. Unplugging and reconnecting the webcam, then reselecting it in OBS, can also help. If the picture works but there is no audio, the microphone is usually either not added or added under the wrong device.

Using a camcorder instead of a webcam

A camcorder's video output generally reaches OBS through the same Video Capture Device source. Usually this requires a capture device that the computer recognizes as a camera, or a camcorder that can present itself as a webcam over USB. Its audio may arrive embedded in that capture signal or may need to be added separately, much like a webcam microphone. Whether a specific camcorder offers clean video output, and how its audio is passed through, depends on the model and capture hardware. No model-specific evidence was available for this guide.

What this guide cannot tell you

No measured data on any particular webcam's microphone was available, so this guide makes no claims about how a given model sounds, how far it picks up speech, or how it compares with a dedicated microphone. Exact menu wording was described from general OBS behavior rather than checked against a specific release. If a label differs on your screen, rely on your installed version's options and the official OBS documentation for that version.
