Why Choose OBS for Live Streaming

OBS Studio is free and open-source, making it one of the most accessible and reliable options for live streaming. It’s used by millions of creators, companies, and production teams for everything from online classes to high-stakes broadcasts.

Some of the top reasons to choose OBS include:

Professional control over video and audio sources

Local recording for saving and archiving streams
No subscription fees or watermarks

What You Need to Get Started

Before setting up your stream in OBS, make sure you have:

A computer with OBS Studio installed
A webcam or external camera
A microphone or headset
A stable internet connection (5 Mbps upload or higher recommended)
A streaming platform account such as YouTube, Twitch, or Facebook

Step 1: Download and Install OBS

Go to obsproject.com and select your operating system (Windows, macOS, or Linux). Download the installer and follow the setup instructions.

Once installed, open OBS Studio. You’ll see the Auto Configuration Wizard, which can automatically detect your optimal settings for streaming or recording. This is a great place to start if you’re new to OBS.

Step 2: Add Your Video and Audio Sources

OBS lets you mix multiple video and audio inputs into one live stream.

In the Sources box, click the + icon.
Choose Video Capture Device to add your camera.
Select your camera from the device list and click OK.
To add audio, click the + icon again and select Audio Input Capture.
Choose your microphone or headset.

You can add more sources like screen shares, window captures, or media files at any time. Arrange and resize each source in the preview window until your layout looks right.

Step 3: Connect OBS to Your Streaming Platform

To go live, OBS needs to connect to your streaming platform using a stream key.

In OBS, open Settings in the lower-right corner.
Select the Stream tab.
Choose your platform from the Service dropdown menu (for example, YouTube, Twitch, or Facebook).
Copy your stream key from your platform dashboard and paste it into OBS.

Here’s where to find your stream key on each major platform:

YouTube: YouTube Studio → Go Live → Stream Settings
Facebook: Live Producer → Stream Setup
Twitch: Creator Dashboard → Stream Key

Click Apply and OK when finished.

Step 4: Adjust Your Video and Audio Settings

For smooth, high-quality streaming, adjust your settings in Settings → Output.

Recommended settings:

Resolution: 1920x1080 for HD or 1280x720 for faster performance
Frame Rate: 30 FPS for general streams or 60 FPS for motion-heavy content
Bitrate: 4500–6000 Kbps for 1080p or 2500–4000 Kbps for 720p
Encoder: Choose x264 for CPU-based or NVENC for GPU-based encoding

You can also open Settings → Audio to make sure the correct microphone and output devices are selected.

Step 5: Create and Test Your Scene

A scene in OBS is a collection of sources that make up your stream layout. You might create one scene for your main camera, another for screen sharing, and another for playback or media clips.

Click the + icon under Scenes to create a new one.
Add your video, audio, and graphic sources.
Preview your stream to check framing, lighting, and audio levels.

Before you go live, run a private test stream to make sure your setup is stable and looks professional.

Step 6: Start Streaming

When everything looks good, click Start Streaming in the OBS control panel.

Your broadcast will begin instantly on the connected platform. You can monitor the stream health and bitrate in the lower-right corner of OBS to make sure everything is running smoothly.

To end your stream, click Stop Streaming. OBS will automatically save your settings for next time.

Step 7: Record Your Stream (Optional)

OBS can also record your live stream locally to your computer.

Go to Settings → Output → Recording, select a save location, and choose your preferred format such as MP4 or MKV.

This feature is useful if you need to keep a copy for training, post-event review, or compliance documentation.

Click Start Recording anytime during your broadcast to capture the footage.
