What screen recording actually does

Screen recording captures everything that happens on your monitor — windows opening, text you type, videos you play, mouse movements — and saves it as a video file you can watch later, edit, or share. Unlike a screenshot, which freezes one moment, a screen recording runs continuously for as long as you let it, so it shows motion and change over time.

The file it creates is a standard video that plays in any media player. You can trim it, add captions, or upload it to a platform like YouTube or Google Drive. Most devices come with a built-in recorder already installed, so you do not need to read anything to get your free guide.

Key Takeaways

  • Windows 10 and 11 have a built-in recorder called Xbox Game Bar that works on any window, not just games.
  • Mac users can open QuickTime Player and select File > New Screen Recording to start without downloading software.
  • Before you record, close browser tabs and notifications you do not want visible, and decide whether you want to capture audio from your microphone or just screen sound.
  • The recording saves to your computer as an MP4 file that you can play, edit, or share when ready after you stop.
  • If the built-in tools feel limited, free third-party programs like OBS Studio offer more control over video quality and file size.

Recording on Windows using Game Bar

Windows 10 and 11 include a screen recorder called Xbox Game Bar that works on any process, not just games. To start, press Windows key + G on your keyboard. A small panel appears in the upper left corner of your screen with recording controls.

Before you hit record, check the settings. Click the gear icon in the Game Bar panel to open Settings. Look for the Audio section and decide whether you want to record your microphone, the sound coming from your speakers, both, or neither. If you are recording a tutorial and want to narrate, turn on the microphone. If you are capturing a video that already has sound, you can leave the microphone off.

Once you are ready, click the red circle button in the Game Bar panel, or press Windows key + Alt + R. A timer appears on screen showing how long you have been recording. When you are done, press Windows key + Alt + R again or click the stop button in the panel. The video saves automatically to your Videos folder in a subfolder called Captures.

Recording on Mac using QuickTime Player

Mac computers come with QuickTime Player, which includes a screen recorder. Open QuickTime Player from your Applications folder or by pressing Command + Space, typing "QuickTime", and pressing Enter. Once it opens, click File in the menu bar and select New Screen Recording.

A small panel appears with a red record button and a dropdown arrow. Click the dropdown arrow to choose whether you want to record your microphone along with the screen. If you want to narrate, select your microphone. If you only want screen sound, leave it set to None. Then click the red record button.

Your cursor changes to a crosshair. You can either click anywhere on the screen to record the entire display, or click and drag to select just one window or area. Once you start recording, a timer appears. When you are finished, click the stop button in the menu bar at the top of your screen. The video opens in QuickTime and you can save it by pressing Command + S, choosing a name and location, and clicking Save.

Preparing your screen before you record

A few minutes of preparation prevents you from having to re-record. Close any browser tabs, email windows, or applications you do not want in the video. If you have notifications turned on, they will pop up during recording and distract from what you are trying to show. On Windows, click the notification icon in the lower right corner and select Focus information to turn off notifications temporarily. On Mac, click the notification icon in the upper right corner and select Do Not Disturb.

If you are recording a tutorial or demonstration, write down the steps you want to show so you do not have to think while recording. Move slowly and pause between actions so viewers can follow along. If you make a mistake, keep recording — it is usually faster to edit out a few seconds than to start over.

Check your screen resolution and zoom level. If text is very small, increase the zoom before you record so viewers can read it. On Windows, right-click the desktop and select Display Settings, then adjust the Scale slider. On Mac, go to System Preferences > Displays and increase the Resolution.

Understanding audio options and what gets recorded

Screen recording captures two types of sound: audio from your speakers (system audio) and audio from your microphone. You control which one records in the settings before you start.

System audio is the sound already playing on your computer — music, video dialogue, notification sounds. If you are recording a video tutorial from a website, the website's audio records automatically. Microphone audio is your voice, which you add if you want to narrate or explain what is happening on screen.

On Windows, if you want to record system audio but Game Bar does not seem to be capturing it, check that your audio output device is set correctly in Settings > System > Sound. On Mac, QuickTime can only record microphone audio, not system audio, so if you need to capture both your voice and a video playing on screen, you will need a third-party tool like OBS Studio.

Finding and playing your recorded video

On Windows, your recording saves to the Videos > Captures folder. You can find it quickly by pressing Windows key + E to open File Explorer, clicking Videos in the left sidebar, then double-clicking the Captures folder. The file is named with the date and time you recorded it and ends in .mp4.

On Mac, the video opens in QuickTime when ready after you stop recording. If you close it without saving, you can find it in your Downloads folder or search for it using Spotlight by pressing Command + Space and typing part of the filename.

To play the video, double-click it. It opens in your default media player. You can trim it, add captions, or upload it directly from there. Most video editing software, including the free tools built into Windows (Photos app) and Mac (iMovie), can open these MP4 files.

When to use third-party recording software instead

The built-in recorders work well for most situations, but they have limits. Windows Game Bar cannot record at very high resolutions or frame rates, and Mac QuickTime cannot capture system audio. If you need more control, OBS Studio is a free, open-source program that works on Windows, Mac, and Linux.

OBS lets you choose your video resolution, frame rate, and file size before you record. You can also record multiple sources at once — your screen, your webcam, and your microphone — and arrange them in a layout. The trade-off is that OBS has more buttons and settings, so it takes longer to learn. For a straightforward screen recording, the built-in tools are usually the better choice.

Other paid options like Camtasia or ScreenFlow offer editing features built in, so you can trim and add effects without opening a separate program. These are worth considering if you record frequently, but for occasional use, free tools are sufficient.

Frequently Asked Questions

Can I record just one window instead of my whole screen?

On Mac, yes — when you click the record button in QuickTime, you can drag to select just the window you want. On Windows, Game Bar records your entire screen, but you can crop the video afterward in the Photos app or any video editor. Some third-party tools like OBS let you select a single window before you start recording.

What if my recording is too large to share?

Screen recordings create large files because they capture every frame. You can reduce the file size by trimming out unnecessary parts in the Photos app (Windows) or iMovie (Mac), or by re-exporting at a lower resolution. OBS Studio lets you choose a lower resolution or frame rate before you record, which creates smaller files from the start.

Can I record my screen while on a video call?

Yes, but tell the other people on the call that you are recording. Most video call software like Zoom and Google Meet will record the call audio and video along with your screen. Check your call software's settings to see what recording options are available.

Why is my recording choppy or laggy?

This usually happens if your computer is running many programs at once. Close unnecessary applications before you record. If you are using Game Bar or QuickTime, they use fewer resources than third-party tools, so try those first. If the problem persists, restart your computer and try again.

Can I edit my recording right after I finish?

Yes. On Windows, open the Photos app, click the video, and use the Edit & Create menu to trim or add effects. On Mac, open the video in iMovie and use the timeline to cut sections or add titles. Both are free and built into your operating system.
