Video setup option 1 configuration (easier)

Multicam video PGM -> visio app

Since version 10.2.10, Multicam can natively output the PGM to be detected as a webcam in the visio-conference app. Open Multicam first and then open your visio-conference app. Select Multicam as a video source. If you don't see it, close and reopen your visio-conference app.

Visio app camera -> Multicam

Depending on the app and type of account used, some apps like Teams or Zoom have NDI output capabilities embedded. If possible, activate this option to send the video to Multicam.

Consult these documentations to set it up on your app :

• Zoom : Using Network Device Interface
• Teams : Broadcasting audio and video from Microsoft Teams with NDI and SDI technology

Then, open Multicam settings > {RoomID} > +ADD INPUT > NDI STREAM > select the NDI stream from your visio-conference app

Declare this video input as a fixed camera.

Video setup option 2 configuration (more complex to set up)

Multicam video PGM -> visio app

Open Multicam settings and enable NDI output.

Install NDI tools, then open Webcam.

Open the settings by left clicking on its icon from the Windows tray.

Click on the gear icon, look for your computer name and select Multicam as a video source.

In your visio-conference app, select NDI Webcam Video 1 as video source.

Visio app camera -> Multicam

If the visio-conference app is open on the same computer as Multicam, you will need a second monitor to capture it with NDI screen capture. If you have only a single monitor, you won't be able to capture the screen. To do so, you will need to create a virtual monitor. See at the end of the article how to do so.

We will assume that you have two physical monitors connected to your PC: one monitor dedicated to Multicam and one monitor dedicated to your visio-conference app.

Install NDI Tools and open Screen capture.

Right click on its icon on the Windows tray to configure it.

Configure the framerate to be the same as the main framerate of your Multicam room.

By default, Screen Capture is capturing the full screen of each of your monitors. Each monitor is 1x NDI video output. But it can also capture a region of interest. To configure the region, verify that Region of Interest is ticked and then click on Configure Rol




 

This will open a new window NDI Region of Interest that you can move and resize to your needs, like this for example.

Then, open Multicam settings > {RoomID} > +ADD INPUT > NDI STREAM > select the NDI stream from your visio-conference app

Declare this video input as a fixed camera.

Audio routing configuration

Multicam audio PGM -> visio-conf app

Install both virtual audio cable drivers A and B. The instructions to install them are in the main folder.

Open Multicam settings > {RoomID} > AUDIO PLAYBACK > + AUDIO

If you don't see the audio driver, click on the refresh button.

Select CABLE-B Input (VB-Audio Cable B)

It is recommended to rename the audio output to make the audio routing simpler to identify.

For audio input, select + AUDIO in AUDIO EXT. DEVICES

Select CABLE-A Input (VB-Audio Cable A)

It is recommended to rename the input as well.

To configure the mix minus audio routing, click on AUDIO MAPPING, then untick the audio input A of the remote guest to the Multicam audio output B.

On Teams, disable any audio processing.

Visio-conf audio -> Multicam

In your visio-conf app, select

• speakers : CABLE-A Input (VB-Audio Cable A)
• microphone : CABLE-B Output (VB-Audio Cable B)

NOTE : disable any automatic audio adjustment level

Settings summary

Multicam

Visio-conference app

Configure a virtual display

If your setup only uses one monitor and your visio-conference app can't output NDI natively, you will need to create a second virtual monitor to configure your screen capture. If possible, it is still recommended to use a physical second monitor though as this procedure complicates the configuration.

Download and install VDD.Control.zip

Start VDD Control.exe, then click on Virtual Display Driver > System > Install Driver

Right click on your desktop and open the display settings to check that the second monitor is now detected by Windows. Change the resolution if needed (1920x1080 recommended).

To see your virtual screen, you will need an RDP tool like VNC (TightVNC, UltraVNC), TeamViewer, AnyDesk, RustDesk, etc.

Connect to your Multicam machine from another computer. Open your visio-conference app and move it to the virtual screen (use the Windows shortcut Win + Maj + → ). Switch monitor from your RDP app and configure the region of interest of NDI screen capture as seen above.
