Strata Lite Remote for BlackMagic Design ATEM Switchers, including ATEM Television Studio, ATEM 1M/E, ATEM 2M/E, Production Studio 4K and 1M/E / 2M/E Production Studio 4K and TelevisionStudio HD.

Strata connects directly to your ATEM switcher via Wifi and your switcher's network connection. It does not require a separate computer.

The Lite version includes basic control of Program and Preview buttons on ATEM Switchers (on iPhone controls Program bus only).

FEATURES (iPad version):
* Control Program and Preview Busses
* Cut and Auto Transition Control
* TBar Control
* Remapping of Source Button Layout
* Connection Indicator with auto-reconnect

Note that the iPhone version does not control preview or Auto, only cuts on the program bus.

NOTE: It does not provide control of the second ME in ATEM 2M/E switchers, although it does control Program and Preview on the first ME of an ATEM 2M/E. This app is not designed for older ATEM Switchers not manufactured by BlackMagic Design. Strata requires iOS 5.1.1 or later and ATEM firmware version 3.4, thru 7.01 Firmware.

NOTE: If you require more complete control of your ATEM switcher, including ME2 of the 2M/E, you should select Strata Pro from the App Store instead of Strata Lite. (Strata Pro provides control of ALL the main buttons on ATEM Switchers plus Midi Control and Macros).

IMPORTANT: The control protocol uses UDP and is fairly intolerant to packet loss and network latency. It is very important to have a reliable, responsive WIFI network for Strata to work reliably. Wifi router performance varies between vendors, and best results have been shown with Apple Airport wifi routers. Some 3rd party routers have shown to be unreliable due to latency or UDP packet loss. Version 1.35 of Strata will handle poor connections much more eleganty. See for more details on optimising your Wifi environment for Strata.

This is one of my favorite apps to use but lately, it has been freezing up on me. Will you have any updates soon?

Hi G-Productions
If your freezing issue is new, most likely its an environmental change - look at your Wifi networking first, since its almost always the cause. Try a wired lightning to ethernet connection.

Great app

Solid functionality, and works like a charm; would love to have cut and fade functionality in the lite version; those are the only extra functions we would need to take this to the next level: that being said, it is understandable that this would be in the more expensive version


Great Idea...poorly implemented.

This is an app Blackmagic should have made. Great idea, but app crashes WAY TOO OFTEN. An app shouldn’t crash if it has trouble connecting with WiFi, and the developer gives the same excuse...”it’s the routers fault.” I don’t blame the router when Safari crashes. There are a lot of bugs to work out of this app before it’s useful in a “real” switching environment. I’ll give it 2 stars for the creativity of attempting something that has real potential to be useful.

Hi Jernap. It's important to understand that Strata is not 'crashing' as you suggest, but it's actually being forcibly closed by iOS because its 'stuck' - due to the network connectivity. If you try a wired ethernet connection I am certain your experience will be totally different (but with the same Strata software). Almost all issues related to apparent 'crashing' or problems connecting are due to intermittent or latent WIFI connectivity. There can be many reasons why your WIFI connection is not reliable, including interference from other devices, and most often, different compatibility with routers. Our users report Apple Airport routers appear noticeably more reliable with Strata. Alternatively you can now setup a wired ethernet connection to your iPad which may completely solve any interference issues.
