Overview

OBS Studio (Open Broadcaster Software) is a free and open-source application for screen capture, webcam recording, and live streaming to platforms like YouTube and Twitch. It is not a video editor: it captures and encodes video in real time, then hands off the resulting file or stream for editing elsewhere.

Its core concept is scenes built from sources — window captures, game captures, webcams, images, browser sources, and audio inputs — that you can switch between live. A built-in audio mixer with per-source filters (noise suppression, gain, compressor) covers most streaming audio needs without extra software.

OBS differs from simpler screen recorders by exposing encoder settings directly: bitrate, keyframe interval, and both software (x264) and hardware (NVENC, Quick Sync, AMF) encoding paths. That flexibility is also its learning curve — a first-time user has to understand encoding basics to get clean output, whereas consumer recorders hide those choices.

It suits streamers, educators recording lectures, and anyone capturing gameplay or tutorials who wants control over quality and file size. People who only need a quick one-off screen recording without configuration are usually better served by a simpler built-in tool, then moving to OBS once they need scenes or streaming.

Key features

  • Scene collections built from window, game, display, webcam, and browser sources
  • Live audio mixer with per-source filters such as noise suppression and compression
  • Hardware-accelerated encoding via NVENC, Quick Sync, and AMD AMF, plus software x264
  • Direct streaming to RTMP/SRT services and simultaneous local recording
  • Studio Mode for previewing a scene before it goes live
  • Plugin and script ecosystem for additional sources, filters, and automation
  • Replay buffer for saving the last few minutes of gameplay on demand

System requirements

Operating system
Windows 11 and Windows 10 (64-bit)
Graphics
A GPU with current drivers supporting DirectX 11 or later
Architecture
64-bit only

How to install OBS Studio

  1. 1. Download from the developer

    Go to obsproject.com/download and choose the Windows installer.

  2. 2. Run setup

    Approve the UAC prompt and accept the default install location unless you need otherwise.

  3. 3. Run the auto-configuration wizard

    On first launch, use Tools > Auto-Configuration Wizard so OBS picks sensible encoder and bitrate defaults for your hardware.

  4. 4. Grant capture permissions

    On Windows, allow OBS through any prompts for screen recording access if your security software asks.

How to use it

  1. 1. Build a scene

    Add sources under the Sources panel — Display Capture for the whole screen, Game Capture for a specific game, or Window Capture for one app.

  2. 2. Set up audio

    Add your microphone and desktop audio under Audio Mixer, then add a Noise Suppression filter to the mic to clean up background hiss.

  3. 3. Choose an encoder

    In Settings > Output, pick NVENC or AMF if you have a compatible GPU to leave CPU headroom for the game or app you are recording.

  4. 4. Record or stream

    Use Start Recording for local files or Start Streaming after entering your platform's stream key under Settings > Stream.

  5. 5. Use the replay buffer

    Enable it in Settings > Output, then trigger Save Replay with a hotkey to capture a highlight after it happens.

Safety and privacy

  • We link only to obsproject.com, the project's own site, for downloads.
  • OBS Studio is open source, so its build process and code are publicly auditable.
Bundled software
The official installer does not bundle third-party offers.
Privacy
OBS runs locally and does not require an account. Streaming keys you enter are stored locally and sent only to the service you configure.

Known risks

  • Third-party plugins run with the same access as OBS itself; install plugins only from sources you trust.
  • Accidentally streaming a source (like a private browser tab) instead of recording is a common user error, not a software flaw — check your scene before going live.

What's new

  • 30.x series

    Recent 30.x releases focused on encoder updates, Windows capture improvements, and expanded hardware encoder support. Check the developer's release notes on GitHub for the current version.

Pros and cons

Pros

  • Completely free with no watermark or time limits
  • Deep encoder control including hardware acceleration
  • Strong plugin ecosystem
  • Handles both recording and live streaming
  • Active open-source development

Cons

  • Steeper learning curve than simple screen recorders
  • No built-in editing beyond basic trimming
  • Getting clean audio/video requires understanding encoder settings
  • Performance depends heavily on correct hardware encoder configuration

Verdict

OBS Studio is the standard free tool for streaming and flexible screen recording on Windows. It asks more setup effort than a one-click recorder, but nothing else free matches its scene and encoder control.

Frequently asked questions

Is OBS Studio free?

Yes, it is free and open source with no paid tier, watermark, or usage limits.

Does OBS Studio edit video?

No. It records and streams; for cutting, transitions, or color grading, pair it with an editor such as Shotcut or DaVinci Resolve.

Why is my recording laggy or dropping frames?

This is usually an encoder bottleneck. Try switching to your GPU's hardware encoder (NVENC, Quick Sync, or AMF) instead of the CPU-based x264 encoder in Settings > Output.

Can OBS Studio record my screen without streaming?

Yes. Use Start Recording instead of Start Streaming — a stream key or connected account is not required for local recording.
