OBS Studio is free, open-source screen-recording software for Windows, Mac, and Linux. This beginner's guide covers install, scenes and sources, the audio check, safe output settings, and the MKV rule that saves a crashed take.

Learning how to use OBS Studio to record your screen takes about fifteen minutes, and most of that time is the first setup. OBS Studio is a free, open-source program for Windows, Mac, and Linux that records anything on your screen — tutorials, gameplay, meetings, or a full desktop — once you have built a scene and picked the right capture source. The setup is the hard part: OBS opens on an empty black preview and waits for you to tell it what to record, and if you pick the wrong source or forget the audio, you get a perfect recording of nothing. This guide walks through the whole first session in order, so your first take is a usable one. If you only need a quick one-off clip, record your screen on Windows 11 with the built-in tools instead — OBS is the right choice when you want control over scenes, sources, and quality.

How do you record your screen with OBS Studio?

To record your screen with OBS Studio, install it from obsproject.com, run the Auto-Configuration Wizard, create a scene, add a Display Capture source, check your audio in the mixer, set the recording format to MKV, and click Start Recording. Your file is saved to the recording path you set in Settings > Output, and you can find it later under File > Show Recordings.

1. Download OBS Studio from obsproject.com and install it for Windows, Mac, or Linux.
2. Run the Auto-Configuration Wizard on first launch and tell it you will only be recording.
3. Create a scene with the + button under Scenes and name it, for example, "Screen Recording".
4. Add a source with the + button under Sources — Display Capture for the whole screen, Window Capture for one app, or Game Capture for a game.
5. Check your audio in the Audio Mixer: Desktop Audio should move when system sound plays, and Mic/Aux should move when you speak.
6. Set the recording format to MKV in Settings > Output, so a crash does not eat the whole take.
7. Click Start Recording, do your take, then click Stop Recording and check the file before you record anything else.

What is OBS Studio, and why is it free?

OBS Studio — Open Broadcaster Software — is a free, open-source program that records your screen and streams live video. It runs on Windows, Mac, and Linux, and it costs nothing because it is built and maintained as an open-source project, not sold as a product. That is why it has no time limits, no watermarks, and no paid tier holding back features — the same download records a ten-minute tutorial and a three-hour stream. Descript's guide calls it the tool many streamers depend on precisely because it is free, and Movavi's guide notes the same: OBS opened screen recording and streaming to a much wider audience by removing the price.

The trade is a learning curve. OBS is a production tool, not a one-button recorder: it gives you scenes, sources, an audio mixer, encoders, and output settings, and it assumes you know what those are. Atekome's October 2026 setup guide puts it plainly — OBS does many of the jobs a hardware vision mixer does in a TV control room, on an ordinary computer, at no cost — and most beginners struggle with the same few settings. That is the gap this guide closes: the five settings that matter, in the order to set them.

OBS does two jobs, and you should pick one before you start. Recording saves a video file to your computer; streaming sends live video to Twitch, YouTube, or Facebook. This guide is about recording. The wizard asks which one you want on first launch, and answering "recording only" gives you sane starting settings for file output instead of stream settings.

Install OBS Studio the safe way

Download OBS only from the official site, obsproject.com. That is the one rule every guide agrees on: Atekome's quick-answer box lists it first, Descript's install steps start there, and Movavi's install section does the same. Do not download "OBS Streamlabs" by mistake — as XboxPlay's beginner guide warns, that is a different product with a similar name. On the OBS site, pick the button for your operating system — Windows, macOS, or Linux — download the installer, and follow the prompts.

On first launch, OBS opens the Auto-Configuration Wizard. Let it run: it tests your computer and internet connection and picks starting video and output settings for you. Tell it you will only be recording, not streaming, and it will set up for file recording. You can change every setting it picks later — the wizard is a starting point, not a lock-in. Descript notes that OBS gives you preconfigured settings you can use as-is or adjust, and that is exactly what the wizard is for.

How OBS thinks: scenes and sources

Everything in OBS is built from two ideas. Sources are the ingredients — a camera, a capture card, a microphone, an image, a text title, a browser window, or a video file. Scenes are recipes — a saved arrangement of sources that you switch between during a show, the way a director cuts between shots. Atekome's guide uses exactly that analogy, and it is the fastest way to understand the interface: you never record "the screen" directly, you record a scene, and the scene holds the sources you added to it.

Sources sit in layers: the one at the top of the list appears in front. A webcam goes above the screen capture; a background image goes below it. Picking the wrong capture type is the number-one beginner failure, so learn the six that matter before your first take.

Two traps live in this table. First, Display Capture records everything on the monitor — including notifications, private messages, and the OBS window itself if it is on the same screen. If that worries you, use Window Capture for one app instead. Second, Game Capture only works for 3D games; for anything else, use Display or Window Capture. If your game recording stutters, update your graphics drivers before blaming OBS — a stale driver is a common cause, and the fix is free.

Build your first recording scene in 5 steps

Start with one scene and two sources: the screen, and your microphone. Everything else is decoration you can add after your first good take.

1. Create the scene. Under Scenes at the bottom left, click +, name it "Screen Recording", and click OK. OBS usually creates one scene for you on first launch; if it did, rename it instead of adding a second one.
2. Add the screen. Under Sources, click +, choose Display Capture, name it "Screen", and click OK. Pick the monitor you want from the Display dropdown, tick "Capture Cursor" if you want the mouse pointer visible, and click OK. Your desktop should now appear in the preview.
3. Add your voice. Under Sources, click +, choose Audio Input Capture, name it "Microphone", and click OK. Pick your microphone from the device dropdown. Speak, and watch the Mic/Aux meter in the Audio Mixer move — if it does not move, you picked the wrong device.
4. Add your face, if you want it. Under Sources, click +, choose Video Capture Device, name it "Webcam", and click OK. Pick your camera, then drag the webcam box in the preview to a corner and shrink it to less than a quarter of the screen. Because sources are layers, the webcam sits above the screen capture — drag it above Display Capture in the Sources list if it hides behind it.
5. Do a ten-second test. Click Start Recording, count to ten while talking and clicking around, click Stop Recording, then play the file back. Check three things: you can hear your voice, the video is the right screen, and nothing private is visible. If all three pass, you are ready for a real take.

Check your audio before you press record

A silent take is a lost take, and OBS will not warn you about it. The audio mixer is the panel at the bottom of the OBS window, and it is the last thing to check before every recording. Descript's guide is blunt about this: OBS assumes you know what a bitrate is and will not stop you from recording silence. So check it yourself, every time.

Two meters matter. Desktop Audio should move when system sound plays — a video, a game, a notification. Mic/Aux should move when you speak. If a meter never moves, that source is not capturing anything: open Settings > Audio and make sure Desktop Audio and Mic/Auxiliary Audio point at the devices you actually use, not "Default". Gist.ly's recording guide makes the same point: replace "Default" with the exact microphone you intend to use. Keep the levels below the red: peaks that hit the top of the meter come out distorted, and no filter fixes a clipped recording after the fact. Descript recommends 48 kHz sample rate and 128 kbps audio bitrate as a starting point, with AAC as the audio format — clean, standard settings for speech and system sound.

Two small features save takes. First, filters: right-click a source in the Audio Mixer and add Noise Suppression if your room has a fan or keyboard clatter, and a Noise Gate if you want silence between sentences. Second, hotkeys: in Settings > Hotkeys, set keys for Start Recording, Stop Recording, and Toggle Mute, so you can start and stop without the OBS window on screen. Gist.ly calls hotkeys invaluable for exactly that reason — you do not want OBS visible in your recording.

The recording settings that don't ruin the take

Open Settings > Output and set the recording side before your first real take. Leave the streaming side alone. Use Simple output mode unless you have a reason to use Advanced — Simple exposes the four settings that matter and hides the rest.

The MKV rule is the one that saves real work. Descript's guide explains it directly: choose MKV if you are concerned about preserving a partial recording in the event of a system crash, because OBS includes a Remux option to convert MKV files to MP4 later. Record in MKV, then use File > Remux Recordings to turn the finished file into MP4 for editing and sharing. Never record straight to MP4 for a long take — if OBS or the computer crashes, the MP4 is usually lost, while the MKV survives.

On the video side, set the base resolution to your monitor's resolution and the output resolution the same to start, with the downscale filter on Lanczos for the best quality if you do scale down. Descript suggests 60 fps for fast-paced action and 30 fps for standard videos, and 10,000 kbps as a starting bitrate for high-quality 1080p — a useful anchor, not a rule: raise it if the video looks blocky, lower it if the file is too big or the computer struggles. Atekome's guide agrees on the shape of it: start at 1080p and 30 fps, because a stable 1080p recording looks better than a higher-resolution one that stutters.

Encoding is the hottest job your computer does during a recording, and a laptop that thermal-throttles will drop frames. If the preview stutters or the Stats panel shows dropped frames, switch to a hardware encoder first — that moves the work to the graphics card — and drop the output resolution second. If you want to know whether heat is the cause, check your CPU temperature while a test recording runs; sustained high temperatures during encoding are a sign to give the machine air and time, not to push the settings higher.

Recording on Mac and Linux

OBS works the same way on Mac and Linux, with two platform differences to know before your first take. On a Mac, use the macOS Screen Capture source instead of Display Capture, and grant Screen Recording permission the first time OBS asks for it — in System Settings > Privacy & Security > Screen Recording. Without that permission, OBS records a black screen on a Mac, and the fix is the permission, not a different capture source. The rest of the steps — scene, sources, audio, MKV, Start Recording — are identical to Windows.

On Linux, the source is called Screen Capture rather than Display Capture — the one naming difference Movavi's guide flags — and you need FFmpeg installed for the video filter to work. Movavi's guide lists Ubuntu 18.05 or higher as the requirement for its Linux steps. After that, the flow is the same: add the source, pick the display, set the recording path, and record.

Recording games, tutorials, and meetings: pick the right capture

The capture you pick should match the job, not the habit. Display Capture is the default everyone reaches for, and it is the wrong choice for half the jobs on this list.

One practical note for all five jobs: recordings eat disk space fast, and a long take at high quality can fill a drive you thought was empty. Before a big recording session, free up disk space on Windows 11 so the recording does not stop halfway — and point the recording path at the drive with the most free space, not the default.

When OBS is the wrong tool

OBS is the wrong tool when the job is small. A thirty-second clip to show a colleague a bug, a quick screen capture for a support ticket, or a one-off recording you will never edit does not need scenes, sources, and output settings. For those, use Windows 11's built-in screen recorders — Snipping Tool, Game Bar, or Clipchamp — which record in a few clicks with no setup. The rule is simple: if you will record more than a few times, or you need a webcam, a microphone, and clean audio, OBS pays for its setup time on the second take. If you will record once, it does not.

OBS is also the wrong tool for a phone screen on its own. There is no mobile version of OBS, as both Movavi's and Descript's guides note. To record a phone with OBS, you connect the phone to the computer with a cable and add it as a Video Capture Device — Movavi's guide walks through exactly that for iPhone and Android — or you use the phone's own built-in recorder. If the phone is the subject, screen record on iPhone directly instead of routing it through a computer.

Fix the 5 problems every beginner hits

Almost every first-week OBS problem is one of these five, and each has a one-line fix. Check them in this order before reinstalling anything.

The mirror effect — OBS recording itself inside itself — deserves a line of its own, because it looks like a bug and it is not. Gist.ly's guide explains it: Display Capture shows everything on the monitor, including the OBS window, so OBS captures its own preview, which contains the capture, which contains the preview, forever. Minimizing OBS during the recording breaks the loop, and so does capturing a second monitor while OBS sits on the first.

Frequently Asked Questions

Is OBS Studio really free?

Yes. OBS Studio is free and open-source software for Windows, Mac, and Linux, with no time limits, no watermarks, and no paid tier. Download it only from the official site, obsproject.com — free copies from other sites may bundle unwanted software.

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

Yes. Add Display Capture for the screen and Video Capture Device for the webcam to the same scene, then drag the webcam box into a corner and shrink it. Sources are layers, so keep the webcam above the screen capture in the Sources list, and do a ten-second test before the real take.

Should I record in MP4 or MKV?

Record in MKV, then convert to MP4 afterwards with File > Remux Recordings. MKV survives a crash mid-take with a playable partial file; an MP4 from the same crash is usually lost entirely. MP4 is the better format for editing and sharing, so remux after the take, not during it.

Why is my OBS recording black?

Usually the capture type is wrong: Game Capture only works for 3D games, and Window Capture only shows the window you picked. Use Display Capture for the whole desktop. On a Mac, a black recording usually means the Screen Recording permission was not granted — allow it in System Settings > Privacy & Security > Screen Recording and restart OBS.

Does OBS Studio work on Mac?

Yes. OBS runs on macOS as well as Windows and Linux. Use the macOS Screen Capture source instead of Display Capture, grant the Screen Recording permission when macOS asks, and the rest of the setup — scenes, sources, audio, MKV, Start Recording — is the same as on Windows.
