This article will walk you through how to connect live switched content in OBS Studio to a Pathable Zoom room using the Virtual Camera
- One computer with Zoom installed
- The latest version of OBS Studio
- A Virtual Audio Cable (Download and install at: https://vb-audio.com/Cable/ )
Configuring OBS Studio:
• Create a new Scene for each video or screen share you plan to live switch between. Within each scene, add the desired video or screen share as a new Source.
• Once all the Scenes and Sources are created, you must configure the audio settings in OBS to properly output to Zoom. Select "Settings" from the controls on the right.
• In the menu that pops up, select "Audio" on the left.
Under "Advanced" change the Monitoring Device to "Voicemeeter Aux Input" then press Apply and OK to save
In each Scene, any Source that includes audio, such as a video/mp4, will show up in the Audio Mixer. Desktop Audio and Mic/Aux show up by default in OBS.
• Click one of the cog wheels on the right side of the Audio Mixer and select "Advanced Audio Properties".
For each line under Audio Monitoring select "Monitor Only (mute output)" This directs the audio through Voicemeeter that we will then connect to Zoom. Once all have been changed, press the "Close" button on the bottom to return to OBS Studio. If you have multiple scenes, be sure to repeat this step for each one.
Note: If you are using a browser window or a screen share as a source, Desktop Audio is the track this sound will be played through. Videos and Music directly added to OBS will have their own track in the Audio Mixer and play directly to Zoom. You will not hear the audio from added videos and music through your desktop speakers.
Similar to Zoom, it is recommended you mute the microphone in the mixer when you are not actively speaking over what is featured in OBS. You may also want to mute your desktop audio in the mixer when not screen sharing to prevent any feedback or multiple audio inputs playing over each other.
• Now that all your sources have been added and the audio has been configured in OBS, we can start the virtual camera. On the right side under controls click the button that says "Start Virtual Camera"
• Once you are in the green room (20 minutes before the scheduled start time) of the Pathable Zoom meeting or webinar, you can access settings by clicking the up-arrow next to the Start/Stop Video button at the bottom left and selecting the last option (Video Settings).
• In Video settings, under "Camera", select "OBS Virtual Camera" from the drop down. You should now see your camera preview change to match what is displayed in OBS Studio. Make sure the "Mirror my video" option below is unchecked.
• Now on the left navigate to "Audio" and in this menu. Under "Microphone" select "Voicemeeter Aux Output." If you have audio playing in OBS you should see the input level meter moving in Zoom similar to the movement of the audio meter in OBS.
• Under "Music and Professional Audio" check the boxes next to "Show in-meeting option to enable Original Sound" and the two options below it for "High fidelity music mode" and "Echo cancellation". This makes sure any media transmitted through the virtual camera retains its audio quality.
• Close the settings window and return to your meeting or webinar. The scene you have playing in OBS Studio is what will be broadcast in Zoom. At the top left of the Zoom window will be the option to turn on "Original Sound". If you select the drop down menu, you can tell Zoom to always use Original Sound when Voicemeeter Aux Output is the selected microphone to preserve this setting for anytime you are using OBS Virtual Camera.
OBS Virtual Camera is now successfully connected to Pathable Zoom!
When you want to disconnect the virtual camera, change your Microphone and Camera settings back to your computer's microphone and webcam in Zoom then press "Stop Virtual Camera" in OBS. It is recommended you change Zoom inputs prior to stopping the Virtual Camera to avoid a blank OBS holding screen being displayed during the transition.
