OBS Studio is one of the great video software available nowadays for video recording and live streaming. On top of that, it is even free and open-source. Available here, it is available for the 3 major systems: Windows, Mac and Linux.
We will see in this quick tutorial how to simply start streaming on Twitch using OBS. As you will see, it’s really straight-forward.
In order to start streaming on Twitch, you will first need to retrieve a key that we will later use in OBS in order to indicate on which channel to stream.
First, connect you on Twitch and on your account in the top bar.
In the appearing menu, click on “Dashboard”:
It will get you on a new page. In this new page, in the left menu, click on « Settings » then on the « Stream Key » link.
When the page is loaded, you will need to click on the button « Show Key »:
When clicking on the button, Twitch will show you an important warning:
Your Stream Key will be used to stream on your channel, thus, it will be extremely important to not share it with anybody. It is purely personal, bound to your account and should remain private.
Please note that as said in the popup, neither Twitch Staff, Admins nor Global Moderators will ask you for this information. This is the same with Stream Maker Staff, we will never ask you this information.
When you are sure to get this point, click on the button « I Understand » and you Stream Key will appear:
This is the key that you will need to copy in OBS Studio.
Note that a « Reset Key » button exists if you need to reset your key.
OBS Studio is quite easy to setup to start streaming. Start it, if the auto-configuration wizard appears, just answers « No » as we won’t need it. This window should appears:
We will start by configuring the Twitch Stream Key in order to be ready to stream to Twitch. Click on the « Settings » in the bottom right corner:
A settings window will appear, in the left menu, click on « Stream » and select Twitch in the « Service » option.
In the « Stream key » field, put your Twitch Stream Key that we’ve retrieved in the previous chapter. This will be used by OBS Studio to indicate on which channel the stream should be broadcasted.
At this point, just a few more steps are necessary and we will be ready to start streaming!
Back to the main screen of OBS, on the bottom left, we see that we’re configuring the scene called « Scene » and that no sources is configured for it.
We will add some sources in order to provide a quality stream:
Let’s start with the « Screen Capture ». In the Sources box in the bottom left, click on the + button:
In the appearing menu, click on « Screen Capture »:
Depending on the OBS Studio version you have and the system you’re using, the value between parenthesis could change or they could not be any parenthesis at all, but we don’t have to really mind about it.
A window will ask you to give a name to this source. Feel free to name it as you want, for this tutorial, we’ll simply label it « Screen Capture »:
A new screen will appear in which you can choose which screen you want to capture and if you want to display your mouse cursor. When this configuration is done, you can click on the « OK » button.
Adding other sources will follow the same ideas, click on the « + » button in the Sources box:
In the appearing menu, choose « Audio Output Capture ».
Again, a small window will appear but this time, choose the option « Add Existing » and select « Desktop Audio », then validate by clicking on « OK »:
Again, click on the « + » button in the Sources box, but this time, choose « Audio Input Capture »:
This small window is opening and you must select the option « Add Existing » and the « Mic/Aux » value, then you can validate by clicking on « OK ».
Click on the « + » button in the Sources box, but this time, choose « Video Capture Device »:
In the small window opening choose a name for this source, we will go with « Streamer Cam Capture »:
When you validate the name, a window is opening to let you configure your camera capture configuration.
Choose the settings you want then validate by clicking on « OK ».
It is quite simple to finally add an overlay to the stream. Click on the « + » button in the Sources box, but this time choose « Image ». A small window will appear to choose the name, we will go with « Overlay »:
The next window will allow you to select the image to use as overlay. If you don’t have any overlay, don’t hesitate to use our creation tool to generate yourself a pretty one!
At this point, only one thing must be taken care of: the order of the sources.
Be sure that the order in the Sources box is:
Congrats! Everything is ready to start your stream! You just have to hit the button « Start Streaming » and start providing content to your watchers!
