Whether you want to record a tutorial, capture gameplay, make a presentation walkthrough, or save a video call, you need a screen recorder. Windows has a basic built-in option through the Xbox Game Bar, but it is limited to single apps and lacks real control over quality or audio. OBS Studio gives you everything the built-in tool does not. It is free, open-source, records at any resolution, captures your full desktop or individual windows, handles multiple audio sources, and is used by millions of content creators and everyday users worldwide. This guide walks you through how to install OBS Studio and use it to record your screen on Windows.
What Is OBS Studio?
OBS Studio, short for Open Broadcaster Software, is a free open-source application for screen recording and live streaming. It runs on Windows 10 and 11, macOS, and Linux. While it is well known among gamers and streamers, it is equally useful for anyone who needs to record their screen for any purpose, from creating how-to videos and software tutorials to recording online meetings or saving gameplay footage.
Unlike simple screen recording tools, OBS works with a scene-and-source system that gives you precise control over what appears in your recording. You can capture your full desktop, a single window, a specific game, or a combination of multiple inputs including your webcam all at once. You choose exactly what goes into the recording and how it is arranged.
How to Download and Install OBS Studio on Windows
Go to obsproject.com and click the Windows button. This downloads the installer directly from the official OBS Project website. Run the downloaded installer file and follow the standard setup steps. When asked whether to install any additional plugins or browser sources, the defaults are fine for most users. Installation takes about a minute.
Once installed, OBS Studio opens automatically. The first thing you will see is the Auto-Configuration Wizard.
Running the Auto-Configuration Wizard
The Auto-Configuration Wizard appears the first time you open OBS. It asks a few questions and then tests your system to choose the best settings automatically. This is worth completing before doing anything else.
When it asks what you want to optimize for, select Optimize just for recording. If you also plan to stream to YouTube or Twitch, select Optimize for streaming. For most people recording their screen for personal or professional use, the recording option is the right choice.
Set your base resolution to match your monitor. For most Windows users this is 1920x1080. Set your frame rate to 60 frames per second for smooth motion, or 30 if you prefer smaller file sizes.
Let OBS run its benchmark test. It will check your hardware and automatically select the best encoder for your system. If you have an NVIDIA GPU it will likely select NVENC, which offloads encoding from your CPU and keeps your system responsive while recording. Click Apply Settings when the wizard finishes.
Understanding the OBS Interface
Before recording anything, it helps to understand what you are looking at. OBS has five main sections.
The Preview area in the center shows exactly what will be captured in your recording. What you see here is what gets saved.
The Scenes panel in the bottom left contains your recording setups. A scene is a collection of sources arranged together. You can have multiple scenes and switch between them, for example one scene for your full desktop and another that includes your webcam alongside a window.
The Sources panel next to Scenes is where you add what gets captured. Sources are the individual elements in your scene, such as your screen, a specific window, your webcam, or an image.
The Audio Mixer shows the volume levels for your audio inputs, typically your desktop audio and your microphone. You can see the levels moving in real time and adjust them here.
The Controls panel in the bottom right has the buttons for starting and stopping recordings and streams.
Setting Up Your First Scene to Record the Screen
OBS creates a default scene called Scene when it opens. You will add a source to it to capture your screen.
- In the Sources panel, click the plus icon to add a new source.
- From the list that appears, select Display Capture to record your entire screen, or Window Capture to record only a specific application window.
- Give the source a name or leave the default and click OK.
- A properties window opens. For Display Capture, select which monitor to capture if you have more than one. For Window Capture, select the specific application window you want to record from the dropdown list. Click OK.
- Your screen or window now appears in the OBS preview area. You can resize and reposition it within the preview by clicking and dragging the red border handles.
If you want to add your webcam to the recording alongside your screen, click the plus icon in Sources again and select Video Capture Device. Choose your webcam from the dropdown. Your webcam feed will appear as an overlay in the preview. Drag it to the corner and resize it to sit alongside your screen capture.
Configuring Audio
Good audio is as important as good video. OBS captures two audio sources by default: your desktop audio, meaning everything playing through your speakers, and your microphone. Both appear in the Audio Mixer at the bottom of the interface.
Check that both are showing activity by playing some audio on your PC and speaking into your microphone. You should see the level bars moving. If a source is not showing any movement, click the gear icon next to it and select Properties to choose the correct audio device.
To adjust the volume balance between your microphone and desktop audio, drag the volume sliders in the Audio Mixer. A common setup is to have desktop audio slightly lower than your microphone so your voice is clear above background sound.
If you do not want to include microphone audio, click the speaker icon next to the microphone track to mute it.
Choosing Where Recordings Are Saved
Before recording, tell OBS where to save your files. Go to Settings in the bottom right Controls panel, then click the Output tab. Under Recording, find the Recording Path field and click Browse to choose a folder. Your Videos folder is a sensible default. Click OK to save the setting.
While in the Output settings, you can also change the Recording Format. OBS defaults to MKV, which is a good choice because if OBS crashes mid-recording the file remains intact and usable. MP4 files become corrupted if recording stops unexpectedly. You can always convert an MKV to MP4 after recording using a tool like HandBrake or VLC.
Starting and Stopping a Recording
Once your scene is set up with the right sources and your audio is configured, you are ready to record.
Click Start Recording in the Controls panel. OBS will begin capturing immediately. The preview continues to show what is being recorded. You can minimize OBS and go about whatever you want to record without OBS being visible in the capture.
When you are finished, click Stop Recording. Your file is saved automatically to the folder you specified. A notification in OBS confirms the recording is complete.
To quickly find your most recent recording without navigating to the folder manually, go to File in the OBS menu bar and select Show Recordings. This opens the recording folder directly.
Setting Up Hotkeys for Faster Control
Clicking into OBS to start and stop recordings is inconvenient when you are in the middle of recording something. Hotkeys let you control OBS with keyboard shortcuts without switching windows.
Go to Settings, then Hotkeys. Find the Start Recording and Stop Recording entries and assign keyboard shortcuts to each. Common choices are Ctrl + F9 to start and Ctrl + F10 to stop, but any combination you find easy to remember works. Click OK to save. From that point, you can control your recording from any app without touching OBS.
OBS Studio vs Windows Game Bar
Windows 11 includes the Xbox Game Bar, opened with Windows key + G, which has a basic screen recording feature. It is quick to access but records only a single application at a time, has limited quality controls, and does not support recording the full desktop or multiple sources at once.
OBS records your full desktop or any combination of windows and sources, gives you full control over resolution, frame rate, and encoding quality, handles multiple audio sources independently, and adds your webcam as an overlay if needed. For anything more than a quick clip of a single app, OBS is the better tool.
Final Thoughts
OBS Studio has a reputation for being complex, and it does have more depth than a simple screen recorder. But for the core task of recording your screen on Windows, the setup is genuinely straightforward. Install it, run the Auto-Configuration Wizard, add a Display Capture source, check your audio levels, and click Start Recording. Everything else, such as multiple scenes, overlays, and hotkeys, is available when you need it and easy to ignore until you do. For anyone who records their screen more than occasionally, OBS is the tool worth learning.
Frequently Asked Questions
Is OBS Studio free to use on Windows?
Yes. OBS Studio is completely free and open-source with no paid tiers, watermarks, time limits, or feature restrictions. It is available for Windows 10 and 11, macOS, and Linux at obsproject.com.
What is the difference between Display Capture and Window Capture in OBS?
Display Capture records your entire monitor including everything visible on the desktop. Window Capture records only a specific application window and continues recording that window even if other windows are in front of it. Use Display Capture for full-screen recording and Window Capture when you want to isolate a single app.
Why does OBS save recordings as MKV instead of MP4?
MKV is the default because it is more resilient. If OBS crashes or your PC loses power mid-recording, MKV files remain intact and playable. MP4 files become corrupted if recording stops abnormally. You can convert MKV to MP4 after recording using VLC or HandBrake with no quality loss.
Can OBS record my webcam alongside my screen?
Yes. Add your webcam as a Video Capture Device source in the same scene as your Display Capture source. OBS will show both simultaneously and you can resize and position the webcam feed anywhere in the preview, typically as a small overlay in one corner of the screen.
Does OBS Studio slow down my PC while recording?
The impact depends on your hardware. OBS is efficient, and if your system has a dedicated GPU, enabling hardware encoding through NVENC for NVIDIA or AMF for AMD offloads the encoding work from your CPU, leaving more resources for whatever you are recording. The Auto-Configuration Wizard selects the best encoder for your system automatically.
