OBS SCENE SETUP

To set up your OBS Scene, please follow the steps below:

1. RESOLUTION AND BROADCASTING PARAMETERS

We need to make sure that resolution and broadcasting parameters are optimized for Facebook Live. If your Live Stream feed is too high-quality, it may freeze or be rejected by Facebook.

Click on "Settings".

Go to "Video", set the resolution to 1280 x 720 and FPS to 30

On "Output" and "Audio", make sure you are using:

- Key-Frame Interval: 1 every 2 seconds

- Max bitrate: 4000 Kbps

- Rate control: CBR

- Audio Sample Rate: 44.1 kHz

- Audio Bitrate: 128 Kbps mono or stereo

 
Then, click on "Apply":

3. ADD SOURCE

In this example, the sources will be a microphone, a webcam, and a "Browser Source".

Click on "+" to add a new source and choose "Browser"..

 Select "Create new" 

Name the source so you can identify it later and click on "OK".

3. ADDRESS

4. SOURCE PROPERTIES

Paste it on "URL" within Properties:

Make sure to set the Video Resolution to 1280x720, then click "OK".

You will see your Source Added in "Sources".

Follow the same steps to add the webcam. Click on "+" and choose Video Capture Device.

If you want to customize your webcam settings, scroll down to view all of your options. For this example, leave the defaults set and click "OK".

Click on "+" to add the microphone and select "Audio Input Capture".

 Choose your microphone from the drop-down menu and click "OK".

Double-check the mixer settings for any duplicate audio feeds. To avoid audio feedback, only one feed should be enabled.

Your scene will look like this:
