Live Stream from ATEM Using Your Mobile Cellular Phone!

Photo Moment - November 17, 2021

If you've ever needed to live stream from your ATEM over a cellular connection, it's easy to set up as a backup — but on location, everything changes!

Need an ATEM Mini?

What this tip is about…

If you've ever needed to live stream from your ATEM over a cellular connection, it's easy to set up as a backup, or even to stream from your home or studio. But when you go on location, everything changes! There's some tricky networking configuration you'll need to set up if you want to connect your laptop to your ATEM in the field — when the USB port is being used by your cell phone!!

Want 5 hours of pure ATEM training?
Watch this:
Just thinking while watching... For less config switching, something like a cheap TL-WR802N usb powered router could act as the bridge between the Atem and the laptop. Would be interesting to see if the router would survive the control bandwith needed.
Going wireless is a bad idea. For whatever reason the ATEM software easily drops a connection to the ATEM when on wifi, and it takes several seconds to reestablish the connection.
What happened Joe, not making any money in photography? You turned into electrician and cell phone sales person. 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Hysterical 😆
I love your classes
I appreciate that!
When streaming using your mobile phone, do you encounter any problems with cache? I have read (and encountered myself) that many have problems with that.
You certainly can, as the mobile upload speed is likely quite a bit slower and less reliable than a high speed land connection. You really want a very good signal, and as fast a connection as possible of course. You should always measure your upload speed using an app like SpeedTest, and test from exactly where you’ll stream, then set an encoding bitrate well under that. I’d say half should be OK.
Great video. Thanks for that gem!

Now to the question: Can the streamdeck be integrated into this local network. setup, and communicate correctly, as well.?
Yes! The streamDeck connects to the computer over USB, but talks to the ATEM over the network.
This is a great tip and so clearly explained, as always. I'm also not so terrified of IP addresses, subnet masks and gateways as I used to be. Many thanks.
Also easy way is to connect iPhone with Mac and share internet connection via LAN and then you have free USB C Port on ATEM to record video on SSD
That's… brilliant. I never thought of that!!
Fantastic. Great video Joseph. It was s so detailed. Hopefully in the future we'll be able to have a SIM Slot for the ATEM Mini, who knows. But for now this works great!. What I've been doing lately is using a 4G Router which has multiple Network ports to connect more than one device.

I'm planning on getting an ATEM Mini PRO or ISO. Still feeling a little bit hesitant on streaming form the ATEM instead of my computer. Been too attached to OBS Studio for a while.
If you’re using OBS for titling or anything like that, then that’s totally understandable. However if you’re just using it for live streaming, then I highly recommend jumping to the hardware encoder of the ATEM!
@PhotoJoseph ​ I only use the ATEM Mini for the Switch. Everything else I'm doing from OBS. Titling, Animations, Lower thirds, Replay ( I also do sports) and extra tweaks. Personally ATEM somewhat feels daunting and I've been watching your videos to ramp up.

I really want to make a more professional live content and perhaps using ATEM might get me there. Also wrapping my head on how to still implement OBS if streaming from ATEM.

Btw, in your experience is there any benefit streaming from ATEM Mini vs. PC? Network efficiency, bitrate and reliability wise?
when you use the 4g router do you plug the wired internet into the router's built in switch?
When connecting directly to the switcher with ethernet from a Windows PC both the PC and the ATEM use APIPA adresses so no additional IP configuration is required
Really! What the heck is APIPA? “Automatic Private IP Addressing (APIPA) is a feature in operating systems (such as Windows) that enables computers to automatically self-configure an IP address and subnet mask when their DHCP server isn't reachable.” — very interesting but it also seems like this was removed from macOS a decade ago? Maybe security reasons? Very interesting!
In order to live stream to Facebook out in the field you’ll need another hotspot for your laptop correct or is there a work around to not to have Facebook active on a desktop in order to hit the go live button
Great point. You should be able to do that from the phone, right?
perhaps you could use castr or restream or one of those multi output solutions instead of being directly in Facebook, then have a secondary device for looking at comment feeds
I'm not sure what use creating the "ATEM in the wild" location was. Your mac seemed to switch back to "Studio" when you plugged in the Belkin adapter so I think it was your Studio settings that you changed after that.
Did it?? Oh snap, you’re right! LOL well that’s embarrassing. I wonder why it did that. I used to use this feature all the time between work and home when I worked a corporate job. No idea why it switched but the intent is still valid.
good catch, but of course while he's filming in the studio he's showing options for when you show up to someone else's event space and don't know how reliable their connections are.
Great video, Joseph!

I also didn't realize that the ATEM had that capability at this point (how did I miss that?).

Also, fun fact, when you have two devices on the same Layer 2 network segment (i.e., where network traffic it not having to traverse a route processor / firewall) you technically don't actually need a gateway at all.

The only time you actually need to specify a gateway is when you need a route "out" of the network you are in. An example would be pulling up a website on your computer. Chances are that website isn't hosted from a system on your local network subnet, there gateway's job is to provide you that route out of that network so your request can eventually get out to the right place, hoping through routers on the internet until it reaches the right network.

So from a pure networking standpoint, you could leave the gateway on both devices - the ATEM and the computer - completely blank and you'd be able to talk.

All of that said, it would be interesting to see if the ATEM software would let you save without entering a gateway. It's possible that they make the gateway field required, which would be silly / lazy of them to do that when you don't need it configured to communicate with hosts on the same network subnet. Would be an interesting test to see!

You are right, I was thinking the same thing. Also, technically with a mask of, only the first 2 “numbers” need to be the same. That is why they call it a mask.
Wow this is next level stuff! I had no idea the Atem Pro could connect directly to a cell phone for streaming, I thought only the Yolobox could do that. I wonder if you could do a comparison in what the dropouts would be on a live stream if you lost the facility's connection and went to your mobile as a backup using the Atem's setup vs. a fully bonded internet solution such as a standalone box or Speedify on a Raspberry PI.
Also can you use this same type of direct to computer ethernet connection to get the Atem on a local WiFi network, for example if you're at a church or event space that has WiFi but no ethernet access? I had no idea you could connect two devices this way without a special ethernet crossover cable, which are difficult to find these days.
As a note, most ethernet port these days are auto sensing, so they don't need a crossover cable. The devices auto negotiate the connection type. 20 years it was important when plugging 2 host devices together.
@Martin Rodrigue Right; I didn’t mention a crossover cable here.
@PhotoJoseph reply was for @Steve R who mentioned it in his comment 😅
@Martin Rodrigue Thanks for that info. It actually was about 20 years ago when I was selling Pro Tools that people needed a crossover cable to connect their fader surface to a computer if they didn't have a switch on site and used wifi primarily, or actually it was common then to have your music computer completely disconnected from the internet. This was still in PowerPC G4/G5 times on the Mac. idk if the Intel Mac Pros started being auto sensing or eventually it just became more common for people to have an ethernet switch as time went on and they dropped in price.
@Eddy04tv sorry I thought I responded to this. I'm not an expert on these but I've watched a few videos on YT, the only one that showed something affordable was Alex Pettit who used an app called Speedify that he ran on a Raspberry PI, otherwise there are hardware solutions from Terradek and others that are in the $1-3k range and may include monthly fees. I saw one event photographer's video that I can't find again where he had a battery powered bonding setup he had made too. If Photojoseph would do an expose on bonding it would be amazing.
thank you for this video! very valuable content on topic the network confuguration with athem mini.
Thanks Victor!
Very clearly explained! Wish the 4G LTE will be built-in someday!
