In following of this "Frequently Asked Questions Cinematography" i wanted to open a FAQ for live video.
As we get a lot of the same questions around here, i will try to put forward links to usefull topics and also will create some topics to put in very usefull data on several points of discussion.

A little introduction of myself. I'm Daniel, 30 years old at the moment of writing, Broadcast engineer and owner of a broadcast company called Xtreemtec Media Productions. With 8 years of expirience with BMD hardware and 13 years of video and broadcast gear.
We have 2 OBV's and 2 Flypacks all build around BMD hardware. The OBV trailer is full 12G build for 4K productions. We also develop hardware for the broadcast industry that comes forth of things we miss in the field or see opertunities to make a new product that will fit into our setup.
My native language is Dutch, so i'm sorry for my gramatical errors that i write up. But i hope everyone can understand me ;)


I will try to set up the topics in logic groups. If you have any suggestions or add ons please let me know. So i can keep building on a good and easy to read FAQ.


Were can i find a driver, software or manual?

Frequently Asked Questions - Atem Mixer

Atem mixer:

> Point 1.01
I connected the USB to my Atem but Media Express can not capture video
Older Atem models build arround 2010 had a capture option by USB. These mixers can be reconised by there passive cooling blocks.
These were the old Atem 1M/E 2M/E (USB 3.0) and Television studio (H.264).
On the newer Atems the USB is ONLY for firmware updates and Network settings!
You will need an external capture device, see the Capture and Streaming post for more information.

> Point 1.02
I connected a source to my Atem but i can not see it on the multiviewer
All sources must match the resolution and framerate of the Atem settings.
This means that if your Atem is set to 1080i50, all sources must send 1080 interlaced with 50 frames per second. If a source does not match these setting it won't show up!!
To match your source to the Atem, first try the settings of the source.
Source is Camera >You have a camera and you want to match it to the Atem. Have a look into the menu of the camera and find the "OUTPUT SETTINGS" Not to confuse with the "RECORD SETTINGS" which are in most cases not linked to the output settings of the camera. Consult the manual of your camera first to see if they mention anything about output settings.
Source is Computer >Most computers have extensive videocard settings. Which go far beyond the default windows settings.
>First match the resolution with windows "Display Settings".
>Select the display you need to adjust.
>Match resolution to a broadcast resolution (1280x720, 1920x1080, 3840x2160) you have set the atem to.
>Now match the Framerate. This can be found under "Display Adapter Settings"
>Go to TAB "Monitor" and under "Monitor Settings" you can select the "Screen refresh rate"
For 1080I50 and your computer can't deal with interlaced? Sometimes will help to set it to 25P. Depending on video card model.
This will in most cases get you up and running. Be aware that if you have a Black background you will not see direct result in your multiviewer!
Source is Mac >
(Have to dig up some info about mac. I'm a windows user. ;)
At the moment of writing a lot of users have troubles with MAC. Mac has activated HDCP in allof there new software releases.. And you will have a lot of trouble to get a direct connection.
If you use an adapter (TB > HDMI , Mini DP > HDMI , ETC) keep in mind that Apple's own adapters are the best to use.. Have seen a lot of issues in the forum solved after they started using official Apple converters. Those cheaper clones often do work fine on a LCD monitor or projector.. But the Atem is really picky about the signal it wants to have.
If you still have problems to get the MAC to match resolution framerate with the Atem.
Try a program called SwitchResX. This software can be tested for 10 days for free and costs 14 euros.
If you still cant get it to work, while it does work on a computer monitor. Then you out of luck and in need of a Decimator MD-HX or BMD UpDownCross HD to solve your problems.
Source is DVD player / Set top box >
A lot of DVD players and Set top boxes have a HDMI port. But while they have a HDMI port and will work fine with a TV behind it. It will often not work with a Atem or HDMI converter. The problem behind this issue is called HDCP encryption. This is a protection key system that protects content (Like played on DVD and Set top boxes) not to be copied. The Atem and almost every broadcast converter does not support HDCP as they would violate laws against protection.
So in short. Most of these sources will not get to work on a Legal way!
Source won't match!! >There will be sometimes a source that will not match or is hard to get up and running with the Atem. This can have several causes.
In most cases it will work with an extra converter like the BMD UpDownCross HD or Decimator MD-HX which will convert an input resolution and framerate to a different resolution and framerate.

> Point 1.03
I have setup my Atem IP adress but the software says "No device connected"
To start, the Atem has a USB and Network connection. The USB is for firmware updates and to configure the Atem with "Atem Setup". Here you configure the IP address of the Atem.
Fresh out of the box the Atem will be pre-configured for
First off you want to connect a cable to the IP port of the Atem. While a Cross cable direct from Atem to PC/MAC will work.. I do NOT recommend it!! Just too many things that can go wrong.

Best is to use a network switch. These switches don't cost a lot anymore. And if you need to buy 1? Buy a gigabit capable switch. This ensures more troughput and less problems when you are putting more and more gear on the same switch.
Another advantage of a network switch is that it will auto detect if a cable is crossed or not and will always connect your Computer and Atem in the right way. Neet thing is that you also can see on the switch if there is a cable connected. (You will see led lights flickering on data)
So you have connected your Computer and Atemto the same switch. You seenetwork traffic by blinking led's.
Configuring the network settings to connect with the Atem. In this example we go by the idea the Atem is still on it's default address ( )
> On Windows
  • Right click the network icon (Down right corner near the clock) "Open network and sharing center".
  • On the left pane "Change adapter settings"
  • Locate the network connection that is your hardwired network connection you have connected to the switch. ( Often called "Local Area Connection" )
  • Right click and click "Properties"
  • In the list select the "Internet Protocol Version 4(TCP/IPv4)" and click the "Properties" button below it.
  • Now a window will open and 2 options are possible, Or the box "Obtain an IP address automatically" is selected, or "Use the following IP address" is selected. If so make a photo of these settings so you can remember them for later!
  • Now we select the second option so we can cahnge the settings to our needs:
    IP address:
    Subnet mask:
    Default gateway:
    As you can see i set the computer to a different IP address as the mixer. But in the same range!
    The IP address may be anything between 1 and 255. As long as it stays in the range 192.168.10.XXX
    But to avoid most used IP addresses 230 is pretty safe. While if you have a network connected with more devices on it. The change can be that a device is already on 10.230.. ;)
  • Click on OK and your settings are saved.
    ** If your computer was connected to the internet by hard wire. your internet connection is now lost.
    The key to get this working with a hardwired connection to internet and the Atem requires a bit more skills and configuring some settings in the advanced menu of IP settings. Google this or consult an IT guy on how to set up fixed IP for internet connection with different IP range.

> On Mac
  • I do not have a Mac. So i need some guidance from somebody with a Mac to write this one out.

> Point 1.04
Atem control connection drops out.
An Atem can drop the connection if data packets don't reach the Atem or Atem Software Control panel.
Atem communicates over network with UDP based data packets. UDP is a protocol that differs from TCP. While with TCP packets it always will verify and report back that packet is received.
UDP is a protocol that does not care about reporting back. A UDP packet is send. And it does not care if it get's received by anyone. It just sends a new packet every time it has a update.
BMD has implemented this in the Atem hardware / software. By design they included some timers inside there protocol to keep track if packets are new and sequential.

So if we would disturb these packets an Atem can drop the connection as it had missed 1 or more packets.
Drop outs can have many causes. Bad network switch, cabling, to many data run trough the switch, having 2 devices in 1 network with the same IP address, Running other UDP traffic like streaming video or other network high demanding network traffic, Wifi connections often have issues! Firewalls or other software on the computer that interfers with the network traffic.

Running Atem with Wifi connections is never recommended. Due too traffic shaping for wireless the protocol can have a lot of issues. Only a few people got it stable working.
If you need to go on wifi check the Livepad Strata website
He has a detailed description on his website why wifi can be a problem and how to solve it..
Strata Website wrote:The ATEM protocol is highly intolerant of connected clients which don't respond to every message in an appropriate timeframe. This means that if your WIFI connection is interrupted, even quite briefly, the ATEM will reject the client connection.

As a comparison - TCP/IP connections and protocols are designed to deal with this sort of thing, with the connection 'guaranteed' to deliver the data (whilst the socket connection is maintained), and most TCP servers and clients have reasonable timeouts to allow for network disruptions of a few seconds.

However, the ATEM protocol uses UDP, where its possible (even common) for data packets to fail to arrive at their destination.

Clearly the ATEM protocol was designed to run on wired network connections with zero packet loss and very low latencies. Running this over a wireless connection requires some care to create as clean a network as possible with minimal interruptions caused by interference, or other WIFI influencing agents.

Maximum number of Connections!!
All Atems have a limit on how many connections you can make to it before it runs out of recources.
This is depending on model. The smaller models can connect fewer devices than the bigger mixers like the 2ME. Will add more info about this later. ;)

Some topics about Atem dropout related issues:
Atem Media pool won't upload but can control Atem switching
2 M/E 4k Network Connection question

> Point 1.05
Atem software keeps prompting for an update!
Atem software and firmware need to be in sync. If you are running a different software version on your computer then there is inside the Atem. It won't connect and will prompt you to update the firmware.
This will happen when the firmware is older or newer then the software running on the computer.
Keep in mind that if you connect with more then 1 computer to the Atem. You need to have installed the same software version on all computers. Otherwise 1 will connect and the other will prompt for a firmware update!
After a Firmware up or downgrade, it is good praktise to remove the power and USB lead for a few seconds to power reset the Atem.
At moment of writing you can not read or see what version firmware is inside the Atem mixer. So the best way is to install the Latest version software on your machine. And update the Atem after that.
You might need a USB A-B lead to firmware update the Atem by USB. But the latest models do support a network update methode.
Setting the IP settings always requires a USB lead plugged into the Atem.

> Point 1.06
How do i downgrade the firmware?
To downgrade the firmware of you Atem mixer or every other BMD device.
  • Remove the software on your computer if you had this installed.
  • Download software version that has the Firmware you need. (See Support section on the website for downloads)
  • Install this software on your computer
  • Run the software. Connect your device to the computer and you will be prompted "Firmware Update required"
  • But Wait Update?? Yes Update. While you are downgrading. The software will always say Update. ;)
  • When update is ready. Remove all power and USB connections. And reconnect after a few seconds.

Models made:
> Echolab Atem
The company Echolab started making the Atem line. Echolab was aquired by BMD in 2010 and redesigned the Atem to make them cheaper and lighter. This started a revolution in the broadcast world. Echolab Atems are not compatible with BMD Atems or controllers or software.
For support on the old Echolab Atems you might want to go to

> Atem Television Studio (old model)
The Atem Television Studio is a lightweight 1ru video mixer with 4 hdmi and 4 sdi connections. While in total a total combination of 6 inputs can be used. Channel 3 & 4 are switchable for HDMI or SDI.

How to render video to be playable by the Hyperdeck??
While the Hyperdecks are very picky on what format they want to have their video to be able to play it. There are no good export profiles or instructions out there at the moment.
I have the intend to make some profiles but i only edit on Sony Vegas and not on Mac or Premiere.. So might need some help from others to get the profiles for common used settings.

For now i have Quick and Dirty way that seems to work and i do advice this way to the forum for a year now.

  • Determine target resolution and framerate needed for your project. (Often used with an Atem mixer)
  • Record with recorder some video in the target resolution and framerate you need to play out. (Record output of the Atem to a card.)
  • Import video into your Editing software and go to options and let "project settings" match based on footage.
  • Save this profile DNxHD in your settings so you can recall this later for other projects.
  • Open the content you want to render for this project and apply the Saved settings for your DNxHD project.
  • Render out and save to card.
  • You should be good to go.

Don't forget that you need the Avid codec pack for DNxHD.. Not sure if every edit software does include this.. Download Avid QuickTime Codecs Lite Edition 2.7.3 (15-09-2016)

1280x720 50P DNxHD Settings for Premiere
1080 and 720 59.94 I and P NTSC ProRes presets for Adobe Media Encoder

A VERY Usefull topic about Hyperdeck encoding presets

File export to Hyperdeck for playback

> Point 3.02
I have network connected to my Hyperdeck but i have no FTP acces?
FTP acces is only available on the Hyperdeck Studio Mini.
On all other hyperdecks the network connection can only be used for remote control. The protocol for remote control is described in the manual of the hyperdeck.

> Point 3.03
How much time can i record on a drive?
Recording time depends on the card or ssd used. But also on the codec you use.
In this topic Hyperdeck Studio Mini File Sizes is more information about the how to calculate file size.

There is an APP called AJA Datacalc. With this software you can select the codec you want to use.
Set the number of channels of audio. (16 with the hyperdecks)
And then you can see how much time you can record on a card or how much GB it takes to record a time frame.
AJA DataCalc for IOS
AJA DataClac for Andriod

For Hyperdeck mini and Video Assist (4k) you need SD cards.
Also remember that you need a card that is recommended and tested by BMD. Other cards might not work due too read write speeds..
What SD card should I use with the Blackmagic Video Assist 4K?

For the Hyperdeck Studio's you need SSD drives of the certified recommended list.
What SSDs should I use with the HyperDecks?

> Point 3.04
How do i control the Hyperdeck Studio Remote
The Hyperdeck Studio is remote controllable by RS422 and Ethernet.
For this to work you have to push the REM button on the Hyperdeck.
The Hyperdeck Mini's don't have a REM button.

Capture, Playback and Streaming

Section for Capture, Playback and Streaming. Work in progress

There are several ways how to realtime capture video to a computer/mac.

BMD offer several different ways of hardware to get your video in or out.
PCI-E Cards for inside a desktop machine.
USB 2, 3 or C for external use.
Thunderbolt for external use.

> Point 4.01
The driver software for all capture hardware can be found in the BMD Support section on the website.
Desktop Video is the configuration, update and driver install software for the capture hardware of BMD.
Media Express is a capture and playback software made by BMD to support their hardware. In most cases this is the software to test with if you have problems with your hardware to other software like Vmix, Wirecast, or others.

> Point 4.02
For internal card we have 2 options. The Intensity card are often called the low end card with capture and playback for HDMI, component and composite plus audio. and Decklink cards.
Decklink card not regonised? 1 way that could solve it.

> Point 4.03
Often we hear people say i have System X and USB3.0 product Y from BMD and it does not work!!
Please always check the minimum hardware requirements for the hardware you buy!
USB 3 Support note (03-01-2018)
Also we have a topic with hardware tested with USB 3.0 products. If you have any questions about USB3 compatiblity or have a different system configuration and got it to work. Please report it there and we will add it to the list.
List of computers that works with BMD USB3.0 products

Intensity Shuttle USB 3 A USB3.0 capture box with HDMI, Component and composite and audio inputs.
This device only supports up to 1080P30 and 1080i60. No 1080P50/60
There is also a Thunderbolt version of this box.

> Point 4.04
Thunderbolt is becoming more used the last few years. While found mostly on MAC machines, more and more Windows machines get hardware support for Thunderbolt or USB-C. While Thunderbolt gets mixed by different hardware vendors with Displayport mini and USB-C, and Several standards within Thunderbolt, 2, and 3. Makes it a bit more difficult in some cases to mix and adapt.
We will go deeper on this topic in the future.

BMD Devices with Thunderbolt:
Intensity Shuttle Thunderbolt
Ultrastudio Thunderbolt Series

Decklink card is skipping frames / dropouts

> Point 4.05
High Sierra and Decklink / Ultrastudio products
There are issues with high sierra and drivers for the capture and playback devices.
Read this topic for several solutions.
BMD Devices not recognised in Mac OSX High Sierra

Tony Rivera wrote:Most likely you see this behavior due to the new security features in the macOS High Sierra.
If you already confirmed that the Blackmagic Design device is showing up in the ▸About This Mac▸System Report…▸USB/Thunderbolt, then you will need to allow it in the System Preferences▸Security & Privacy▸General.

There you will need to look for a text message similar to "System software from developer Blackmagic Design was blocked from loading." as well as the [Allow] button right next to that message. Click the button to allow.
Because this message may only appear for about 30 minutes after the installation of the Desktop Video software on your computer, you may need to perform a full reinstall of the Desktop Video software. To do so:
  • 1. Navigate to the Application▸Blackmagic Desktop Video… and launch the Uninstall Desktop Restart your computer as prompted.
  • 2. Download and install the most current version of the Desktop Video (10.9.11 and later). Follow on-screen prompts to restart the computer.
  • 3. Once the system is fully up, go to the System Preferences▸Security & Privacy▸General and Allow the Blackmagic Design system software.
  • 4. Due to a rarely occurring unexpected behavior in the macOS 10.13. X you might need to perform steps 1–3 once more.

Not been here in a while, and see these FAQ posts. Nice job. I see at least one of these links to a thread which I am heavily featured in, and where i posted links to Adobe Media Encoder presets. I may take a look and see if there are any others I might make and add.
