How to Record a Video on Your Computer

Recording a video on your computer lets you capture screen activity, webcam footage, or both for tutorials, presentations, gaming clips, or personal messages. This guide covers built-in tools for Windows and macOS, plus a reliable free option, so you can start recording without installing extra software.

What You’ll Need

• A computer running Windows 10/11 or macOS (any recent version).
• A webcam and microphone if you want to record yourself or add narration (most laptops have them built-in).
• Enough free storage space on your hard drive (a 5-minute 1080p video uses roughly 200–400 MB).

Step-by-Step

On Windows 10 and 11

1. Open the Xbox Game Bar. Press Windows + G on your keyboard. If you’re recording a game, the Game Bar works automatically; for other apps, it still works fine.
2. Start recording. In the Game Bar overlay, click the circular Record button (or press Windows + Alt + R). A small timer appears in the corner of your screen.
3. Stop recording. Click the square Stop button in the timer widget, or press the same keyboard shortcut again.
4. Find your video. Open the Game Bar again, click the Gallery icon (folder icon), and your recording will be listed there. By default, videos are saved in Videos > Captures.

On macOS (any recent version)

1. Open QuickTime Player. Go to Applications and launch QuickTime Player.
2. Start a new movie recording. From the menu bar, click File > New Movie Recording (for webcam) or New Screen Recording (for your screen).
3. Choose your source. Click the small arrow next to the red record button to select your camera, microphone, and recording quality.
4. Record. Click the red button. For screen recording, you’ll be prompted to select the entire screen or a portion. Click to start.
5. Stop and save. Click the stop button in the menu bar (or press Command + Control + Esc). QuickTime will open the video in a new window; go to File > Save to store it.

Using OBS Studio (free, both platforms)

1. Download and install OBS Studio from the official website (obsproject.com). It’s open-source and free.
2. Set up your sources. In the Sources panel, click the + button. Choose Display Capture for your screen, Window Capture for a specific app, or Video Capture Device for your webcam.
3. Select your audio. Click the + in Sources and add Audio Input Capture for your microphone. Make sure the correct device is selected in the mixer.
4. Start recording. Click Start Recording in the bottom-right corner. You’ll see a red indicator.
5. Stop and locate the file. Click Stop Recording. The video is saved in the folder listed under File > Settings > Output (default is Videos on Windows, Movies on macOS).

Common Mistakes

• Recording the wrong screen. On macOS, if you have multiple monitors, make sure you select the correct display when prompted. In OBS, choose the right display from the dropdown.
• No audio. Your microphone may be muted or not selected. Check the system sound settings and the recording app’s audio input.
• Low-quality video. Default settings may record at 720p or 30fps. For better quality, adjust the recording resolution in the app’s settings (OBS: Settings > Video; QuickTime: the arrow next to the record button).
• Huge file sizes. Uncompressed or high-bitrate recordings can fill your drive quickly. Use a lower bitrate or compress the video after recording.

Tips

• Close unnecessary apps to free up CPU and RAM, which prevents laggy recordings.
• Use a wired microphone or a USB mic for better audio quality than built-in laptop mics.
• Plan your recording. Write a quick outline of what you’ll show or say to avoid long pauses and retakes.
• Test your setup first. Record a 10-second clip and check the audio and video before doing the full recording.
• Use keyboard shortcuts to start/stop quickly: Windows + Alt + R on Windows, Command + Control + Esc on macOS (for QuickTime).

Troubleshooting

• Game Bar won’t open or record. Make sure your PC meets the minimum requirements (Windows 10/11). If the Game Bar doesn’t respond, restart your PC. For non-game apps, try running the app in windowed mode.
• QuickTime screen recording shows a black screen. This happens when the app is blocked from screen capture. Go to System Settings > Privacy & Security > Screen Recording and enable QuickTime Player. You may need to restart the app.
• No sound in the recording. Check your microphone input level in system settings. In OBS, ensure the audio source is not muted and the correct device is selected. If you’re recording system audio, you may need to enable stereo mix on Windows or install a virtual audio cable on macOS.
• The video file is corrupted or won’t play. Stop the recording properly (don’t force-quit the app). If the file is still unreadable, try playing it with VLC media player, which handles more formats.
• Recording is choppy or laggy. Lower the recording resolution or frame rate in the app’s settings. Also, close background programs that use heavy CPU or GPU, like games or video editors.

Frequently Asked Questions

Can I record my screen and webcam at the same time?

Yes. OBS Studio allows you to add both a Display Capture and a Video Capture Device source. In QuickTime, you can’t do both in one recording, but you can record screen and webcam separately and combine them in an editor.

What is the best free screen recorder for Windows?

The Xbox Game Bar is built-in and works well for quick clips. For more control (multiple sources, overlays), OBS Studio is the most popular free option.

How do I record a video of myself on my computer?

Open QuickTime Player on Mac and select New Movie Recording. On Windows, you can use the Camera app (press Start, type “Camera”) to record a webcam video, or use OBS with a Video Capture Device source.

Where are my recordings saved?

On Windows, Game Bar saves to Videos > Captures. QuickTime asks you to save manually. OBS saves to the folder you set in Settings > Output (default is Videos on Windows, Movies on Mac).

Can I record a video without installing any software?

Yes. Windows has the Xbox Game Bar (built-in) and the Camera app. Mac has QuickTime Player (built-in). Both allow basic screen or webcam recording without extra downloads.

How do I reduce the file size of a recorded video?

Use a lower resolution (like 720p) or lower bitrate in your recording settings. After recording, you can compress the file using a free tool like HandBrake or the built-in Windows Photos app (trim and export).
