How To Use Obs To Stream On Twitch

Streaming on Twitch has become a popular way for individuals to share their gaming experiences and connect with others who have similar interests. One of the most popular broadcasting software used by streamers is OBS (Open Broadcaster Software). As a streamer myself, I have found OBS to be a reliable and user-friendly tool that provides a seamless streaming experience. In this article, I will guide you step by step on how to use OBS to stream on Twitch, based on my personal experience.

Step 1: Download and Install OBS

The first thing you need to do is download and install OBS on your computer. OBS is available for free and is compatible with Windows, Mac, and Linux operating systems. You can download the latest version of OBS from the official website here. Once the download is complete, follow the installation instructions to set up OBS on your computer.

Step 2: Configure OBS

After installing OBS, open the software and you will be prompted to configure it. OBS will automatically detect your hardware settings, but you can make adjustments as needed. You can choose your preferred language, set up your microphone and webcam, and customize other settings according to your streaming needs.

Step 3: Set up Twitch Stream Key

In order to stream on Twitch using OBS, you will need to obtain your Twitch stream key. Your stream key is a unique code that allows OBS to connect to your Twitch channel. To get your stream key, log in to your Twitch account and navigate to your Twitch Dashboard. Under the settings tab, you will find your stream key. Copy the key and go back to OBS.

In OBS, click on “Settings” in the lower-right corner. In the left sidebar, select “Stream.” Under the “Service” dropdown, choose “Twitch.” Paste your stream key in the “Stream Key” field. Click “Apply” and then “OK” to save the changes.

Step 4: Configure Stream Settings

Now it’s time to configure your stream settings in OBS. Click on “Settings” again, but this time select “Output” in the left sidebar. Under the “Output Mode” dropdown, choose “Simple” if you are new to streaming or “Advanced” if you have more experience and want more control over your stream settings.

Next, choose your desired streaming bitrate and encoder. The bitrate refers to the amount of data transferred per second during your stream, and the encoder determines how your stream will be compressed. Higher bitrates and more advanced encoders will result in better video quality but require a faster internet connection.

Under the “Video” tab, you can set your base canvas resolution and output resolution. It’s recommended to set your base canvas resolution to your monitor’s native resolution and your output resolution to 1280×720 or 1920×1080 for optimal streaming quality.

Step 5: Add Sources

Sources in OBS refer to the different elements you want to include in your stream, such as your gameplay footage, webcam, overlays, and alerts. To add sources, click on the “+” icon under the “Sources” box in the main OBS window. You can choose from a variety of sources, including “Display Capture” to capture your entire screen, “Game Capture” to capture a specific game window, and “Video Capture Device” to add your webcam.

Arrange your sources by dragging and resizing them within the main OBS window. You can also adjust their properties, such as opacity, position, and size, by right-clicking on the source and selecting “Properties.”

Step 6: Start Streaming

Once you have set up your sources, it’s time to start streaming. To do this, click on the “Start Streaming” button in the main OBS window. OBS will now connect to your Twitch channel using the stream key you provided earlier. You can monitor your stream’s status, view the chat, and manage your stream settings in the OBS interface.

Remember to interact with your viewers, respond to chat messages, and keep the conversation engaging. A successful stream is not just about the gameplay, but also the connection you build with your audience.


Streaming on Twitch using OBS is a fantastic way to share your gaming adventures and connect with a community. By following the steps outlined in this guide, you can confidently set up OBS and start streaming like a pro. Remember to personalize your stream with overlays, alerts, and a unique personality that sets you apart from others. Happy streaming!
