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!!

Your presentation is great and informitive for streaming using the phone for streaming. How about using the phone camera wirelessly as input into atem mini. I have searched for the subject but have not been able to find a solution except that I can pay around $500 for connecting phone to atem
Thanks for this, it's very helpful!

I have a question that I haven't been able to sort out: what do I do if the USB C port on the ATEM doesn't recognize my iPhone? Your popped right up in the ATEM software, but my ATEM doesn't recognize my phone. I'm using an iPhone SE, with a Belkin lightning-to-USB C cable. Any thoughts?


EDIT: I figured it out! You have to have your Personal Hotspot enabled for the ATEM to recognize that it's a streaming option.
Glad you found it!
Excellent! Thank you!
Love it.. this is a key feature! Does it work through a usb hub whilst also ISO recording? Asking for a friend.. 😁
Hmm. Good question. The USB protocol switches decoding what you plug in. You can use a hub for multiple drives, but not to go to a drive and to the computer. Since it’d be sending the compressed data to the phone, that’s probably the same protocol as connecting to a computer and not to a hard drive but I don’t actually know. You’ll have to test it!
@PhotoJosephthanks Jo.. trying to get my research accurate prior to purchase.. appreciate the note & love the channel!
Yup you deserve me subbing and a like
Hehe thank you!
Great video PhotoJoseph! I have a question that may fit within the context of your video.

BACKGROUND: We stream our worship services live. I currently use an ATEM Mini Extreme, connected to PC via USB. PC is hardwire connect to network switch. We use four blackmagic cameras, three are hardwired to ATEM and one is connected via Hollyland wireless transmitter. For Tally for the wireless cam, we just bought a CUEBI wireless tally - but I realized that in order to connect to ATEM, both the cuebi and the PC have to be connected to my router (which for streaming purposes, I do not want to connect PC to router). We do not stream directly from ATEM. We use Livestream Studio.

QUESTION: The cuebi connects via wifi. Here's the kicker - even with PC connected to network switch, cuebi cannot communicate with ATEM, even though atem is connected via ethernet to router, as well as cuebi connected via wifi to said router. May be a long shot question but here goes - Is there a work around in order to maintain my hardwire connection to my network switch, using THAT connection to live stream, but somehow to get the cuebi to connect to ATEM without use of a router?
I don't totally follow. Why not have everything on the network; PC, ATEM, Livestream Studio and the CUEBI? Wouldn't that resolve the issue? You're referring to the hardware Livestream Studio right? So the stream happens from there; so what if everything else is on the network, too? I haven't used the CUEBI but it appears that it has to be on the the same network as the ATEM, just via WiFi, right? So again, just put everything on the network, no?
@PhotoJoseph Well, I do not want to stream from router - I'd need to hardwire directly into network switch. In order for cuebi to work, it'd need to connect to router via wifi. If I connect the ATEM to the router via ethernet, and also connect to computer via usb (said computer would also be connected to network switch), the atem does NOT read the router network IP is picking up the network that the PC is connected to.
Why are you connecting the computer and the ATEM via USB? If they are both on the network, then a USB connection is not needed. The ATEM Software will find the ATEM on the network.
@PhotoJoseph Do you offer phone consult/support? I need a little help here.
Hi Joseph, can I ask you if the atem switches to the secondary connection only if the first one is completely off? If the primary connection is slowed down not allowing a good streaming, does the switch happen on the secondary line anyway? Maybe you can set a threshold not to exceed via software? In any case for me, having two connections to the atem is enough to buy it. Thank you for your tips
That’s actually a really interesting question. I’ve only tested it with a complete disconnect; I don’t know if it’ll switch over if it simply has not enough throughput. You can download the user guide from Blackmagic website. Just go to the Support page and search for the ATEM. You can download the installer which includes the manual, even if you don’t yet have the hardware. As far as I know, it will only switch on a disconnect, and there definitely is no threshold setting. But I don’t know if it’ll switch if the bandwidth is simply too low.
@PhotoJoseph ok, thanks for the answer. I'll check the manual
Can't you just teather the laptop to cell phone and then usb connect the atem to the laptop rather then setting up a network?
No. The ATEM doesn’t get data over usb.
Your videos are terrific. I have subscribed. I have a live event coming up, super camera on the main speaker, one camera on a WS as a fall-back (OMG) shot and a PowerPoint presentation. My boss is most worried about the internet connection since we'll be in a building with not much AV support and questionable internet connectivity but we are in a city so we do have pretty good cell service. I'm planning to use an Teradek, VidiU Go with two nodes, connected to the CORE service feeding the various web streaming services. So, I'm covered on potential signal loss. I'll have a ATEM Mini Extreme. One HMDI out will feed by monitor for Multi-view. The other HDMI out will feed an Atomos Shogun to record a Pro-Res version of the live event. One USB-C will connect the ATEM to my Mac computer. So, question: how do I connect this set-up to the VidiU Go...via an Ethernet cable? Via the other USB-C output on the ATEM? Or should I use one of the HDMI out's to feed the VidiU Go and use the Other USB-C out on the ATEM to record the show on to a fast SSD? This is the one big thing that I find SO confusing about live streaming. Thanks.
Sounds like you’re covering your bases! Yes the vidiu needs Ethernet unless it’s just being used for the cellular backup. But it also needs an HDMI feed for the program. Since you’re recording on a shogun, that has an hdmi out. Pass the signal through the shogun into the VidiU!
@PhotoJoseph Duh...what an idiot I am. Yes, the HDMI out of the Shogun into the VidiU Go. That's perfect. Somnetimes we can't see the forest for the trees. Thanks for your clarity.
Is there a hub that works with the ATEM Mini? I would still like to record my stream to an external SSD, but in this configuration, it’s being used by the iPhone…
Hm interesting question. You CAN use a hub to connect multiple drives. You can NOT use a hub to connect a drive and a computer (different USB protocols and the port auto-switches). But I don’t know which protocols a tethered phone lives on! You should post a question on the Blackmagic forums, and report back here if you find out.
Hi Joseph, awesome content! I'm having a strange thing happen with the Atem Mini Extreme ISO and my Gonine A/C power adapters. For some reason when I have the adapters in my Canon R5 and R6 and plug my HDMI cables to the Atem then my USB-C from the Atem to my computer the Atem Controller software shows my cameras going black but only when I have the A/C adapters in the cameras. When I have regular Canon batteries in, I don't have any issues. I can't find anything online pertaining to this issue and was looking for some help since you know this device so well. Any guidance would be greatly appreciated, thanks for your time.
Odd. Do the Cameras work with the AC adapters if you disconnect the atem?
Can we use USB type c hub? Plug all such as iPhone as tethered device, usb disk to record channels and connect Atem Mini Pro ISO to computer for Atem S/W Control… it should logically solve this issue. Please suggest.
No. A hub can be used to add additional recording disks but that’s it. A hub can’t be used to make it a webcam and a recorder. Those are two different usb protocols. The USB port switches depending on what’s plugged in. It can be either/or but it can’t be both at the same time.
Awesome 😎
My atem mini pro is ON AIR switch blinking when I go for strem
Insufficient bandwidth or incorrect internet setup
@PhotoJoseph Thanks for reply sir. I identify problems it hardware problem lan port is not working
it0s interesting, but i guess using VPN (in my case) would be a problem for streaming,

but great explanation
If you have to use VPN then yes VPN + cellular is a pretty slow combination but the only way to know for sure is to test!
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 😆
@PhotoJoseph absolutely nothing funny about it. you have no clue when it comes to photography.
I don’t know who hurt you, but I hope you get the help you need.
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.
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.
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!
