Multiview return for Remote (over VPN) switching


I want to use an ATEM controlled remotely from anywhere in the world. How are folks setting up the Multiview (with local audio) return for the remote operator to use? I want to be able to preview everything, therefore do not want the remote operator using the program out. How do I combine the MV with the house audio into NDI and send it back to the remote operator. What is the best (and economical) NDI encoder? This of course witll be done over VPN.

This is a great idea and here is what I suggest:

  1. VPN into a local PC on the same network as the ATEM and make sure that PC can see the ATEM on the network using the ATEM software control. You now have control of the ATEM.

  2. Connect the ATEM USB out (assuming we are talking about the ATEM Mini line if not then you will need a USB video capture card instead) to the same PC you are using locally to control the ATEM. Now it will be your choice on what software you want to use to get the audio and video sent back to the remote operator. I would suggest Skype because a) Skype has very low latency with 2 way capabilities and b) also allows the remote operator to send audio back to the PC (as a talkback channel in the production world) which could be taken (routed) from the PC sound card back into the audio chain (example into an audio mixer and talk back to your camera people or the talent on location) should you need this functionality.

NDI protocol does not play nice with the ATEM gear in general and also adds additional latency as the audio and video will need to be encoded and decoded. This means by default the remote operator will be many milliseconds if not seconds behind the live action so I would avoid NDI altogether.

Hope that helps.

The only problem is that ATEM does not output multiview over usb, so you need a capture card anyway.

Thanks Gimzo, I forgot the USB output is not capable of having a choice of what is being output.

I’m still hoping they add that feature eventually

In my instance, I need to be able to switch using an unreliable connection, likewise I don’t have the bandwidth for NDI, so here’s the solution I use:

Multiview going through an HDMI Splitter, one output to a monitor, other to a Thunderbolt Capture Device (Those cheap $15 USB Capture cards off Amazon/AliExpress would work great for this use case)

Zoom that uses the multiview feed as the camera source.

Expose my Companion instance to the internet using ngrok. Then pull up that URL on an iPad.

I use a screen sharing software (such as VNC or Google Remote Desktop) to setup the Zoom call and ngrok remotely. Because of the aforementioned bad internet connection at home or when traveling the frame rate of screen sharing isn’t high enough to actually switch the show. So after everything is setup on that computer, I can disconnect the screen sharing software and just rely on the remote Companion instance (which takes up very little data per each button press) and whatever quality I can get over Zoom at the time. If I need to have camera opps on comms, I would just have them dial into the Zoom call with headphones.

I don’t use a VPN.
