2. Configuring OBS Studio for Streaming to Twitch

Now, we can jump to the OBS Studio setup. If you don’t have it installed on your computer, you can download OBS Studio here. This software is available for Windows, Mac, and Linux, and go here for a detailed installation guide.

After installation, there are 2 ways you can set up OBS Studio –

2.1 OBS Studio Setup with Auto-Configuration Wizard

If it’s your first time running it, a wizard will pop up to guide you through the setup. We recommend that you go through this process first but expect to fine-tune your setup later.

From the 3 options, pick Optimize for Streaming, recording is secondary. It’s best to use 1080p for Base Resolution and set fps to 60. In the next window, select Twitch as your Service, enter your stream key, and hit next. It will take a few moments before you get the results.

If you don’t know what is Bitrate or Resolution, check out our beginners article on Bitrate and Resolution in Video Streaming and Compression.

Note: You can also access this process by going to Tools > Auto-Configuration Wizard.

However, if your setup is limited, that may not be possible. If that’s the case, take a look at Twitch’s broadcasting guidelines to find out how to make your stream run smoothly.

2.2 Manual Setup of OBS Studio

Although useful, this wizard is often not as reliable as it could be. That’s why you might want to visit Settings and change a few things at your own discretion.

First, let’s go to the Video section to play with resolution, framerate, and filter settings. Base Resolution is what you will see in OBS Studio, while the Output Resolution is what you will broadcast to your viewers on Twitch. Make sure to hit Apply before you exit.

Now, let’s move to Output and focus on Video Bitrate. If you are going to stream in 1080p, your bitrate should be between 4500 to 6000 Kbps (4.5 to 6 Mbps). However, keep in mind that if your internet speed is insufficient, higher resolution may result in an unwatchable stream. You can test your upload speed here and then compare it with the guidelines we mentioned above.

Scenesare used for changing multiple sources at once, in case of intermission, technical problems, beginning of the game, etc. Start by creating a game scene.
