Using mimoLive with the ATEM switcher: Step-by-Step Tutorial

Using mimoLive with the ATEM switcher: Step-by-Step Tutorial

This tutorial is dedicated to my friend Jay Creighton, who just dived in and purchased mimoLive and an ATEM Production Studio 4K! This is a fantastic combination for someone who has a Mac and wants to be able to switch multiple cameras, add graphics, or playback pre-produced video content––plus stream and record.

I'm going to go step-by-step through the entire process of setting up mimoLive to work with an ATEM switcher and an UltraStudio 4K or UltraStudio Mini Monitor. When we get near the end, I'll split off into a couple of different possible workflows, so you can customize the setup for your needs. As always, feel free to contact me at jason@dvestore.com if you have any questions!


Step 1: Get mimoLive


Step 2: Install the ATEM Software

Go to  https://www.blackmagicdesign.com/support and download the latest version of the ATEM software for OSX.



Once installed, in your Applications folder you'll find the Blackmagic ATEM Switchers folder.

Step 3: Connect Your ATEM

Before you launch the ATEM Setup App, power up your ATEM and connect it to your Mac via both ethernet and USB. You can connect the ATEM directly to your Mac via ethernet, or you can have them both connected to an existing network. The ethernet connection is for controlling the ATEM and the USB connection is for setting the IP address on the ATEM.



For those that are new to the ATEM, I'll note here that the ATEM does not come with a power cord, nor does it have a power button!

If you have a recent Macbook Pro, you may need a Thunderbolt to Ethernet Adapter (pictured below) in order to connect to the ATEM.



Launch the ATEM Setup app. 




With a USB connection, you should see this screen:

Click on the settings icon to go to the IP settings:



Here you can see the default network settings: 


You want the ATEM's IP address to be in the same range as your computer's network settings. In this case, I changed my network settings to be in the same range as the default ATEM settings:

Notice that the two IP addresses are not identical, but in the same range. Once you have your computer communicating across the network with your ATEM, the ATEM Setup app will show a new icon that launches the ATEM Software Control app.


Step 4: Configure the ATEM

When you click the icon, the ATEM Software Control app opens.



Click on the gear icon in the lower left corner and set your desired video standard.



Plug your cameras into the ATEM inputs and connect a monitor to the Multi-View output.

Important: Your cameras must be outputting a video signal that matches the ATEM video standard set in the previous step! For example, if you set your ATEM to 1080p29.97, your cameras must be putting out 1080p29.97. Some cameras are limited in what formats they can send out via HDMI or SDI. Check your camera settings and/or manual to see what your camera is capable of.



Next, connect the ATEM Program Out:



To the UltraStudio In:



Step 5: Configure the UltraStudio

Don't forget to plug in the UltraStudio to power it up and then connect it to your Mac via Thunderbolt.



You may also use another version of the UltraStudio, such as the following, but not all versions of the UltraStudio support the same capabilities. More on that later.



You'll need the Blackmagic Desktop Video Software, which you can get here:  https://www.blackmagicdesign.com/support/family/capture-and-playback


After download and installation, you will find the Blackmagic Desktop Video folder inside your Applications folder.

Launch the Blackmagic Desktop Video Setup app and it should "see" your UltraStudio.


Click the settings icon and set your output format to match mimoLive and the ATEM. Disable both "1080PsF On" and "Remove Field Jitter on Pause". Set the SDI Configuration to Single Link and hit "Save".



Step 6: Configure mimoLive

Now launch mimoLive and set the document settings to match the ATEM video standard settings:


Hit, "Create new document" and mimoLive opens your new document.

Watch the video below to see how to set up mimoLive to control your ATEM!



Made it through the video? Great! 

Now that you have mimoLive "talking to" and controlling the ATEM, we can discuss a few of the options for outputting finished video from mimoLive.

Option 1 would be to stop here and just use mimoLive's built-in Program Output window for monitoring your production. You could utilize the recording and/or streaming options to immortalize your work and share it with others. 

Another variation of this option is to play out the program full-screen via VGA, DVI or HDMI. You'll need a Thunderbolt to VGA , DVI or HDMI adapter, or you can use the built-in HDMI port if your Mac is so equipped. The screengrab below shows where to go to select which monitor to use for fullscreen playout.



This image shows the Playout button activated (in red).



And here's a quick shot of my Macbook Pro playing out to an inexpensive HDMI computer monitor.



Option 2 would be to use mimoLive's SDI Playout ability to send your live program out to a dedicated monitor so you can see every pixel of the final output in all it's high def glory. You can still use mimoLive's recording and streaming options as well. This doesn't use the Mac's second screen output, but uses a Thunderbolt attached UltraStudio device to generate a baseband video output. Any of the Blackmagic UltraStudio devices will support this option. 

The image below shows how I have this set up to output program video via the UltraStudio 4K.



Make sure to click the SDI Playout icon to turn it on. It will turn red when engaged.



Option 3 is to send the video and graphics back to the ATEM for compositing there. This makes the ATEM the center of your production system and lets you see everything on the ATEM's multi-view output. You can also use the outputs of the ATEM to send your program to dedicated streaming or recording devices. The downside to this option is that you forfeit mimoLive's recording and streaming abilities. 

To set this up, you will need an UltraStudio device that supports multi-channel SDI playout, such as the UltraStudio 4K or UltraStudio 4K Extreme. 

You will first need to connect the two outputs from the UltraStudio 4K...



...to two inputs on the ATEM. I've connected OUT A on the UltraStudio to IN 7 on the ATEM and OUT B to IN 8.



In mimoLive, set your SDI Playout Keying Mode to "External", as shown below.  

Note: This only works with commercial or broadcast licensed versions of mimoLive.


In the ATEM Controller Layer settings, you'll need to set your Program to "None".



Then you will need to go into your ATEM Software Control and set up the Down Stream Key as shown below. The Fill Source is set to Camera 7 and the Key Source is set to Camera 8.

The DSK 1 ON AIR button must be engaged and lit up as shown.



You can tweak the Clip and Gain sliders to taste (above), or just click the Pre Multiplied Key button (as shown below).



Now when you engage your SDI Playout in mimoLive...



...your ATEM Multi-View output will look like this!



If you wish to feed the ATEM Multi-View back into mimoLive, to view everything on your Mac, then watch the following short video.



I hope this tutorial has been helpful for you. I think mimoLive and the Blackmagic ATEM is a potent combination :) Reach out if you have any questions!  jason@dvestore.com
