10 Tech How-To

How to Record with a Webcam on Windows and Mac

Guide 10-31409 · Updated · Step by step

This guide walks you through recording video with your built-in or external webcam on both Windows and macOS. You’ll learn the built-in tools first, then free alternatives, and how to fix common issues like a black screen or no audio.

What You’ll Need

  • A computer with a built-in webcam or an external USB webcam plugged in.
  • A microphone (built-in or external) if you want audio.
  • Windows 10/11 or macOS 12 or newer.
  • Optional: a free app like OBS Studio for more control.

Step-by-Step

On Windows 10 and 11

  1. Open the Camera app. Click the Start button, type Camera, and press Enter. This is the built-in app that records video.
  2. Switch to video mode. If the app opens in photo mode, click the video camera icon on the right side of the screen (or press Ctrl + V).
  3. Check your camera and microphone. Look at the preview. If you don’t see yourself, click the camera-switch icon (top right) to toggle between multiple cameras. Click the microphone icon to make sure it’s not muted.
  4. Start recording. Click the big red record button (or press Ctrl + R). A timer will appear.
  5. Stop recording. Click the red square button (or press Ctrl + R again). The video is saved automatically.
  6. Find your video. Open the File Explorer and go to This PC > Videos > Camera Roll. Your clips appear there.

On macOS

  1. Open QuickTime Player. Go to Applications and double-click QuickTime Player.
  2. Start a new recording. In the menu bar at the top, click File > New Movie Recording.
  3. Select your camera and mic. Click the small arrow next to the record button (the red circle). Choose your webcam from the Camera list and your microphone from the Microphone list.
  4. Record. Click the red record button. You’ll see a blinking timer.
  5. Stop and save. Click the stop button (black square) in the QuickTime controls. Then go to File > Save, choose a name and location, and click Save.

Using OBS Studio (Free, Both Platforms)

  1. Download and install OBS Studio from the official website (obsproject.com). It’s free and open-source.
  2. Set up your source. In the Sources box (bottom left), click the + button, select Video Capture Device, name it, and click OK. Choose your webcam from the Device dropdown.
  3. Add audio. Click the + again, choose Audio Input Capture, and select your microphone.
  4. Start recording. Click Start Recording in the bottom right corner. The button changes to Stop Recording.
  5. Find the file. After stopping, OBS automatically saves the video to your Videos folder (or the path set in Settings > Output).

Common Mistakes

  • Recording in photo mode. The Windows Camera app opens in photo mode by default. If you press the big button without switching to video, you’ll get a photo, not a video.
  • Forgetting to save on Mac. QuickTime does not save automatically. If you close the window without saving, the recording is lost.
  • Wrong camera selected. Laptops with multiple cameras (front and rear) or external webcams can default to the wrong one. Always check the preview before recording.
  • Muted microphone. The mic icon in the camera app or the system volume being muted will produce a video with no sound.
  • Low light. Webcams perform poorly in dim rooms. The image will look grainy or dark. Add a light source in front of you.

Tips

  • Clean your lens. A smudged lens makes the whole video look blurry. Wipe it with a microfiber cloth before recording.
  • Look at the lens, not the screen. When talking to the camera, glance at the lens to simulate eye contact.
  • Record a short test clip. Check the audio level and video quality for 10 seconds before the real take.
  • Use a stable surface. If your webcam is external, place it on a solid surface or a tripod to avoid shaky footage.
  • Close other apps. Video recording uses CPU and bandwidth. Close video calls, streaming, and heavy games to prevent lag or dropped frames.
  • For longer recordings, use OBS. The built-in apps are fine for short clips, but OBS handles hours-long recordings and offers better compression settings.

Troubleshooting

Black screen or “Camera not found”

  • Check privacy settings (Windows). Go to Settings > Privacy & security > Camera. Make sure Camera access is on and the specific app has permission.
  • Check privacy settings (Mac). Go to System Settings > Privacy & Security > Camera and ensure the app you’re using is checked.
  • Close other apps using the camera. Zoom, Teams, or your browser may be holding the camera. Close them and try again.
  • Restart the computer. A simple reboot fixes many driver glitches.

No audio in the recording

  • Check the mic input. In Windows, right-click the speaker icon in the taskbar, select Sound settings, and verify the correct input device is selected.
  • On Mac, check System Settings > Sound > Input. Make sure the correct microphone is selected and the input level is not zero.
  • Test the mic with a different app. Open Voice Recorder (Windows) or Voice Memos (Mac) to see if the hardware works at all.

Video is choppy or laggy

  • Close bandwidth-heavy apps. Downloads, uploads, and streaming can interfere.
  • Lower the resolution. In OBS, go to Settings > Video and reduce the output resolution to 720p.
  • Use a wired connection. If you’re recording a video call, Wi-Fi can cause drops. Plug in an Ethernet cable.

The webcam light is on but no image

  • Try a different USB port. For external webcams, a dead or underpowered port can cause this.
  • Update the driver (Windows). Open Device Manager, find Cameras, right-click your webcam, and choose Update driver.

Frequently Asked Questions

Where does the Windows Camera app save videos?

Videos are saved automatically to This PC > Videos > Camera Roll in your user folder.

Can I record with my webcam without installing anything?

Yes. Windows has the Camera app, and Mac has QuickTime Player. Both are pre-installed and can record video with audio.

What file format will my webcam recording be in?

Windows Camera app saves as MP4. QuickTime saves as MOV. OBS can save as MP4, MKV, or FLV depending on your settings.

How do I record my screen and webcam at the same time?

Use OBS Studio. Add a Display Capture source for your screen and a Video Capture Device for your webcam. Then arrange them in the preview and record.

Why is my video sideways or upside down?

This usually happens with external webcams. In OBS, right-click the video source, go to Transform, and use Rotate 90° or Flip Vertical to fix it.

Can I record with my phone as a webcam?

Yes, apps like EpocCam or Iriun let you use your phone as a wireless webcam on both Windows and Mac, but they require installing the companion app on your computer.
