[VIDEO] How to setup a Livestream?


With most of the world’s population staying at home, live-streaming is the next best solution for people to meet and interact online – whether it’s for an online seminar, gaming, product launches, auctions, I’m sure we have all seen some of these livestreams somewhere.

Today we are going to learn how to setup a simple livestream for an simple online class (one speaker with powerpoint slides). If you’re looking to livestream other content such as gaming or music production, fret not, the same set of instruction applies.

The tutorial will be split into 4 main parts – Getting the hardware & software, a quick overview of OBS, adding sources into our scenes and lastly Going Live.

1. Hardware & Software

Here are what you’ll need to start:

  • A computer (duh.)
  • Webcam or Built-in Camera on your device
  • Microphone or Built-in Microphone on your device
  • Microsoft Powerpoint or whichever software you want to show your audience.
  • OBS Studio (Free)
  • Stable internet connection

Start by downloading & installing OBS studio on your computer.

2. Overview of OBS Studio

This is the part where we set up the live stream. We start by acquiring the different sources such as Webcam, audio from microphones and content on your computer into OBS.

We start by launching OBS studio on our computer. Let’s quickly run through what are the different areas in OBS.

  1. Scenes
    We can think of scenes as templates that you set up beforehand before we start our live stream. In this tutorial we are going to learn how to set up 2 scenes – one with just our camera and the second one is a picture-in-picture (PIP) of the camera and the powerpoint slide.
  2. Sources
    Like it’s name suggest, sources are what we want to place inside each scene, so you can have different sources for every scene. Example of sources are Cameras, Microphones, Window Capture, Photos etc.
  3. Audio Mixer
    The audio mixer is where we can monitor and control the volume of the audio. Straightforward.
  4. Scene Transitions
    This is where we can change how we want the transition to be like when we switch between scenes. There are 2 basic option in OBS – Fade and Cut.
  5. Controls
    This is where you hit the nuclear launcher button. BOOM and you’re live. Here’s where all the master controls are.


3. Adding Sources into Scenes.

We need to create 2 scenes for this online class that we are doing.

  1. Cam only.
  2. Cam + Powerpoint Slides (PIP)

Creating the First Scene

Step 1: Create 2 scenes. There’s already one scene created for you by default, so add another scene by clicking on the ‘+’ button on the bottom left. Name the new scene ‘Cam + Slides’ and click ‘Ok’ for now.


Step 2: Rename the first scene because I like to keep things neat and tidy. Right click on ‘Scene’ and rename it to ‘Cam only’.

Step 3: Start adding sources into our ‘Cam only’ scene. Click on ‘Cam only’, and click on the ‘+’ on the Sources panel.

Step 4: Select “Create new’ and then click ‘Ok’ to create new video capture device. Under Devices, choose the camera that you want to use (probably your computer’s built-in camera) then click ‘Ok’.

Step 5: Nice, we have added the camera into the ‘Cam only’ scene. You should be able to see your face now but it probably isn’t full screen. Let’s fix that by right clicking on ‘Video Capture Device’ under Sources > Transform > Fit to Screen. Now your face should be in full-screen glory.


Creating our ‘Cam + Slides’ Scene.

Step 1: Click on the ‘Cam + Slides’ scene first, then add ‘Video Capture Device’ as taught above. This time round we do not need to enlarge our webcam feed because we want to have our powerpoint slides take mainstage.

Step 2: Time to add in our powerpoint slide. Launch Microsoft Powerpoint – Do not maximise the window, resize it to roughly 60% of your screen.

Step 3: Change the slideshow settings by clicking on the ‘Slideshow’ tab > Set Up Slideshow > Browsed by an Individual (Window).

What this does is instead of having your slideshow going full-screen on your computer, it will now appear as a window on your computer so you can continue to monitor your livestream on OBS in the background. Click on ‘F5″ to start slideshow and you will see what I mean.

Step 4: Go back to OBS, add another source and select ‘Window Capture’.

Step 5: Rename the source to ‘Powerpoint’ and click ‘Ok’.

Step 6: Click on the dropdown menu for ‘Window’ and choose ‘Microsoft Powerpoint’

Step 7: Well done, we have added our slides into OBS, now all we need is to resize the slides and our webcam as we desire. We can resize the images using the red adjustment anchors around the source.

Step 8: As you can see, our beautiful face is being blocked by our slides. To fix that, simply drag ‘Video Capture Device’ on top of ‘Powerpoint’ in the Sources panel. This works based on the principles of layer, the source at the top of the list will be at the forefront of your scene.


Step 9: After we are done moving things around, the ‘Cam + Slides’ scene is complete.

Configuring audio:

Next we move on to the Audio panel. By default, there are 2 sources of audio added in for you – Desktop audio and Mic/Aux. Desktop audio is the sound from your computer, if your powerpoint slides contain sounds, this is where it will fall under. Mic/Aux for our tutorial today will be our voice via a microphone.

Step 1: Click on the gear icon on the Mic/Aux channel and click on ‘Properties’.

Step 2: Select the microphone that you want to use (probably the built-in microphone on your laptop) and click ‘ok’.

Step 3: If your microphone is working, you should see the levels moving. You can adjust the volume of microphone using the blue volume slider under the volume unit meter. If you want to mute/unmute your microphone, simply click on speaker icon beside the gear icon to do so.

Audio is now configured! Let’s move on.

4. Going live.

Now that we have our scenes, sources and audio ready, it’s time to configure the going live part. For this tutorial we will using YouTube as our livestreaming platform.

Step 1: Click on ‘Settings’ under the Controls panel > Stream.

Step 2: Under Service, Choose ‘YouTube/YouTube Gaming’.

Step 3: Go to YouTube and click on Go Live located on the top right corner.

Step 4: Key in the details of your livestream such as title & description. We also have the option to schedule the livestream for a later time if we want to. Click ‘Create stream’ when you’re done.

Step 5: Your Stream Key as well as Stream URL will be provided to you in the next page. Copy the Stream Key & Stream URL into OBS Studio. Click ‘Ok’ when you are done.

Step 6: Click on ‘Start Streaming’ and go back to Youtube. You should be able to see a preview of your stream. Once you are ready, just hit the ‘Go Live’ button on the top right corner of your screen.


Step 7: To switch between the 2 scenes that we have created earlier, simply click on the name of the scene under the Scenes panel. You can use ‘Cam only’ to start off the livestream and interact with your audience before switching to ‘Cam + Slides’ to begin your presentation.

Step 8: Use Powerpoint as per normal to change slides, mark annotations etc.

Hurray, you now have your live-stream ready to go. Remember to share this tutorial with your friends if you find it helpful, cheers!
