OBS Studio is free, open-source software for video recording and live streaming. Used worldwide, it's a favourite with streamers because it's free, powerful, and easy to use.

Important!

Some computers are not powerful enough to support live streaming.

Make sure you run your preview tests to avoid technical problems.


2- Open OBS Studio.

3- In the lower right corner, click on Settings.

4- Select the Stream tab.


5- Under Service, select Custom...


6- Back in the Streaming tab for your event in our management tool, click the Start button.

7- Copy the URL address that you will find in the URL field.

8. Paste it under the Server line in OBS Studio.


9- Paste the Key into the Stream Key from OBS Studio into the Stream tab.

10. Click Apply.


11. If your default settings haven't selected the camera you will use, click the + next to Controls in the bottom section, then select Video Capture Device.

12. Select the device to be used and the desired resolution.

Warning!

Before you start your test, please keep in mind that once you've started the preview, you won't be able to change the video quality.

13. Return to our management tool, and go to your event's Streaming tab.

Click Start to test your connection.

WARNING!

IF YOU STOP THE SERVER, YOU WILL NEED TO CHANGE THE RTMP LINE IN OBS STUDIO FOR YOUR EVENT.

Each time you start and stop the server, a new RTMP URL is created. You must change this data in OBS Studio, or your attendees will not be able to see your event.

14. Click Start streaming under Commands, in the bottom right corner, to start the preview test. If you conduct your tests early, before the event begins, you may need to repeat this step. Please allow a few minutes to check your connection before the event starts.


Please note that the connection sometimes fails. If that happens, click Stop streaming, wait a few seconds, and then click Start streaming again.

This way, you can see a preview of your video.

If you don't like the sound and image, you'll feel the same way during your event. If so, find out how you can optimize the broadcasting of your video.

15. If your tests are conclusive, click Go Live a little before the predetermined start time of your event to begin broadcasting.

If you encounter a connection problem when previewing, click the Back button to return to the previous step and retry.

Your attendees will only be able to see the broadcast from the time you have set for the event to start.

Please note that a delay between the preview and your device is normal. It is not representative of what attendees will see.

Please don't rely on the delay you see in the preview to start your event.

With OBS Studio, the average delay between what you see on the software and what the attendees see is 20 seconds. We recommend including an image, a video, or an advertisement as a buffer period before your event starts.

16. Click End the event when your event is over. 

17. Made a mistake? Clicked on End the event too soon? Want to switch to another broadcasting device quickly?

Click Start over to restart the process from the beginning.


** Pro Tip **

Create buffer periods before and after the event.


BEFORE

Give your latecomers a little time to get to the viewing page, and give the others a chance to chat. Create a countdown video (as long as you'd like) before your broadcast starts.

This is an excellent time to introduce your partners, if any, and to create an atmosphere that reflects your event's personality!


AFTER

Leave some time for your customers who have pressed pause during the broadcast to finish the video by adding a short video at the end of your broadcast. This could be a logo, a still image, an advert, or a pre-recorded video.

Moreover, it will allow your customers to share their impressions of your video.
