How can you use the Virtual Camera in Open Broadcaster Software (OBS) for your webinar?

Open Broadcaster Software (OBS)

OBS is software with lots of options for live video streaming. Combined with Virtual Cam it can also be used to incorporate professional equipment into your webinar. It’s also possible to use OBS for easy broadcasting of multi-camera webinars, as well as creating different settings for the broadcast. For example, picture in picture.

In OBS you have the option to add sources. When you connect your camera to your computer, it can practically always be used as the video during the webinar. Using Google you can find instructions for practically every type of camera to set this up. In Google, search for your camera brand and type this in combination with terms like “as webcam”, or “to computer”.

The next step is to recognize the camera as a webcam. For this, you can use your OBS software. OBS is an acronym for “Open Broadcaster Software”. It’s a free open-source software to record videos with and use for live streaming. It can do a lot more than showing your video as a webcam. For example, you can merge multiple camera images (split-screen), add filters, layer multiple camera images (picture-in-picture), and you can add images and other types of media to your video. The possibilities are endless!

For now, we're keeping things simple. Let’s use our OBS software to convert our external video as a webcam. This is how:

  • Download OBS at https://obsproject.com.

  • Open OBS, and add your camera source to “Sources”. Can’t find this setting? Perhaps there’s a problem with the detection of your camera.

  • In the 'Controls' section, select 'Start Virtual Camera'.

  • Open the WebinarGeek app and open your (test) webinar.

  • In the “Settings” select the “OBS Virtual Camera” input as your camera.

With just a few clicks you can convert your external camera into a webcam for your webinars.
