Introducing MixEffect

Happy to announce the availability of my next app, MixEffect, on the App Store. MixEffect is a professional tool for controlling Blackmagic ATEM switchers from your iPhone or iPad. If you have an ATEM switcher, such as an ATEM Mini, Mini Pro, Mini Pro ISO, Mini Extreme, or Mini Extreme ISO, MixEffect is going to be your switcher’s new best friend.

MixEffect’s familiar interface gives you quick access to virtually everything you need — from switcher control, macros, audio, media, editing palettes, recording and streaming — to run your video productions. MixEffect then turns the dial past ten with animated SuperSource transitions, Video Follows Audio, customizable layouts, Shortcuts support, and much more.

Here’s an abbreviated list of features. For more information, visit the website.

  • Switcher Management: Control multiple ATEM switchers. Sync your switcher settings between all of your iCloud-connected devices.
  • Buttons: Access buttons and functionality present and missing from your physical ATEM switcher.
  • SuperSource: Enjoy beautiful transitions when switching between SuperSource layouts — no macros required. Use drag and drop to rearrange your boxes. Save your favorite preset layouts and share them with others.
  • Custom Switcher Pages: Create your own switcher pages that have the exact controls you need.
  • Macros: Organize and visualize your macros like never before.
  • Media: Upload still images from your iOS device straight to the media pool on your ATEM switcher.
  • Audio: Display real-time levels for every audio input. Adjust the gain, fader gain, frames delay, pan, and more.
  • Editing: Quickly adjust your transition, upstream key, downstream key, and SuperSource settings.
  • Automations: Control your ATEM switcher with Siri and Shortcuts. Automatically switch your inputs when your audio levels reach a certain level with the Video Follows Audio feature. Enjoy extensive keyboard shortcuts support for selecting inputs, highlight SuperSource boxes, running macros, and more.
  • Streaming: Organize your streaming destinations without having to edit XML files.
  • Recording: Manage your disk recordings straight from MixEffect. Start and stop recordings, set the filename for recorded videos, and switch disks all from your iPhone or iPad.
  • Auxiliary: Set the source for each of your Auxiliary outputs.
  • Color Generators: Adjust the colors of your Color 1 and Color 2 inputs.
  • Simulator: Don’t have an ATEM at the moment? Test out the interface using the built-in ATEM simulator.

Manage your live productions confidently with MixEffect!

  1. Hi there Adam, I have downloaded your app and have been trying it. Love is so far, one question about the animation of the SS! it is playing a bit jerky, does it rely on the device for the animation or is only triggering the ATEM to do the transition? will it preform differently on different (newer) devices?



    1. Gaby: What kind of iOS device are you using? What speed have you set for the animation? And how are you connected to the network (Wi-Fi or wireless). MixEffect instructs the ATEM to do the transition, but it calculates the frames and the delay between each frame. Knowing more about your setup will help me understand what’s happening better.

      1. David Shough

        I’m seeing the same problem. All animations are a bit jerky, regardless of what the settings are (I’ve tried all the variations.) I’m using a 12.9″ 2020 iPad Pro – plenty of power and RAM.

      2. I’m wondering if it’s your Wi-Fi connection to the ATEM. Have you tried if using it with Ethernet makes things smoother? I have a 2018 iPad Pro, so performance should be better on yours.

      3. David Shough

        I have an ethernet connector coming tomorrow. Will test and check back. Thanks

      4. David Shough

        BTW… Your app is incredible. Amazing that you were able to build this and hit the mark so well on your first version. Bravo!

        One feature request to consider: It’s frustrating to set the SuperSource view to Grid, click away to do something else, and when you come back to the SuperSource tab, the Grid view doesn’t stick. During a live broadcast, it would really help for the Grid view to stay and not reset, as that’s the best view for triggering animations. Thanks for considering.

      5. Hear you on the Grid view. Thinking of the best way to handle this, since the view is not technically part of the SuperSource section in the app (Presets, Art, and Copy). Stay tuned.

        Hey Adam, I have quite a few questions to ask you please, let me know if we can chat her, or you can list your email/phone number

        Hey Adam, my team and I were trying to use our ATEM Mini Pro switcher remotely from the phone. Everything is going great. However, we are having trouble connecting the video of our HDMI inputs on We have done the following; Added Remote Webview, Added the URL into the URL section. The only thing we need assistance with is getting our Black Magic camera inputs onto the website while remaining on the Remote Webview. Please can you guide us from this point? Every effort is greatly appreciated. Thank You!

      8. When you say get your Blackmagic Camera Inputs onto the website, what do you mean? Are you streaming from the ATEM to a place like YouTube or Vimeo? Are you inputting your Program video feed onto a computer that’s running OBS or StreamLabs, which is then streaming to YouTube or Vimeo?

        From the ports of your ATEM:

        HDMI Out -> Multiview -> Mac/PC running You’ll need some kind of capture card to take the HDMI output from the ATEM and convert it into USB (unless you have an HDMI capture card). This is the input that will get.

        Ethernet -> Internet -> YouTube/Vimeo/RTMP server. Use the Output tab in MixEffect to stream the Program feed to a streaming service.

        USB-C -> Mac/PC. This is the Program feed from the ATEM delivered as a webcam to your computer. If you’re using Zoom (or OBS) to streaming, you’d select the Blackmagic Design Camera in the Video section.

      9. Kim

        Hello Adam, thanks for your swift response, greatly appreciated.

        We already have a computer PC that is already doing as shown below;
        “HDMI Out -> Multiview -> Mac/PC running You’ll need some kind of capture card to take the HDMI output from the ATEM and convert it into USB (unless you have an HDMI capture card). This is the input that will get.”

        We are looking at the possibility of having the same function on the phone app. Is that possible?

      10. As of today, iPhones and iPads cannot take HDMI input, so you’ll have to use a Mac/PC to do this so the iPhone/iPad can view it via and Remote Webview.

    Hi Adam, I am a tech guy from Hong Kong, which helping small churches in Hong Kong to establish their online production platform. May I ask if there is possible to request a sponsor for a free mixeffect pro version so that I can utilize the tablet to serve those in need?

    Many Thanks and stay healthy,

  3. Hi Adam – I absolutely LOVE this app of yours – BRAVO!! I do have a question, and I hope you can help. I’m able to connect the ATEM extreme to the app on my ipad and control it (via an ethernet dongle), but I can’t get streaming to work on that same connection. I’ve been changing settings left, right and center, and I can’t make it work. I CAN connect using a straight USB-C cable from the aTEM to the iPad, but that gets me streaming, but the MixEffect app then doesn’t see the ATEM for control. Can I make both streaming (using my ipad for the internet) and control work from just one of those cables? I even tried connecting them both using a dongle which has USB and ethernet, but that didn’t work either. I don’t know WHAT I’ve done wrong…lol. Thanks so much – I hope you can help!!

    1. So, your ATEM Extreme needs to be connected to a router via Ethernet for streaming to work. Then, the iPad is connected to that same router via Ethernet or Wi-Fi. The USB-C connection can go to your computer should you want to see its output as a webcam or control it with ATEM Software Control on your Mac/PC. MixEffect control of the ATEM doesn’t work when you direct connect the two devices via USB-C. Let me know if that works.

  4. Thanks, Adam. That worked just fine. I do have a new question. In regards to supersources, I’m able to change the sources for each box, and I believe I’ve saved it by hitting set all settings, but when I change to another preset and then come back, to the previous one, the box sources are always reset to what they originally were. It seems that they only retain the setting that is set up using the original ATEM software. Is there some setting I’m missing to allow me to have presets saved with differing sources?

    1. To save a preset, you have to long-press on a preset. The Set All Settings button is used when recording macros (so that all the settings you set are recorded to the macro).

      1. Mark Payne

        Ohhhhh! Got it. I missed that – thanks again. Really – this app is genius – and the shortcuts – incredible!! You are one smart man!

    Church here, please consider compiling for older iOS so that we may repurpose older equipment to use your app with. Thank you!

    1. Unfortunately, MixEffect takes advantage of features that are only in iOS 14, so that will remain the minimum OS. The oldest iPads and iPhones that can use iOS 14 can be found here:

    I am a new user to ATEM Mini Pro Extreme and to MixEffects on a 12.9″ iPad Pro with a keyboard. The task this afternoon was to create a series of SuperSource layouts. And I couldn’t be more frustrated with the UI.

    I’ll describe what I tried to do and where things got confusing.

    1. I started diddling with the big 4-box template shown in the middle of the screen to change default sources, Clearly just tapping on the various boxes does nothing. Enter the rabbit hole of unmarked blue icons to try to figure out source switching.

    2. Figured out that the presets is actually a list that scrolls sideways. Yecch. Long list. That doesn’t scale. The four-box icon at the upper switches into “list” view but tapping it a second time doesn’t get you back out again. Calls up and dismisses a menu. Further down another rabbit hole… Back out with the <SuperSource menu. on the right side of the screen. Two menu controls that don't work together?

    3. And what are all those blue buttons below the presets for? Hmm. Nothing is labelled.

    4. Edited a template and named it. Then it disappeared as soon as I finished editing. WTF?
    Then I worked out, that it's 'there" but now stuck in a long list of templates I don't care about.

    4a. Now, how do I get all these templates I want to edit/use listed at the top so i can find them quickly?
    Or, how am I going to call up "my" edited templates quickly during a live presentation?

    5. And why are there then TWO templates listed every time I edit something. Oh yeah, in a list of templates there is another template entry that isn't a template entry but the active screen being sent out. It's bordered green which means nothing, of course, if you are new and using "CUT' and not "Preview".

    I'll learn all the UI "Baseball rules", but really…

    1. I would take a look at the SuperSource documentation here: and watch the following video tutorial on YouTube:

      1. To change the box sources, enable the Show Box Sources toggle at the bottom of the screen.

      2. The horizontal scrolling list is for quickly choosing a preset when you are on the main SuperSource page. If you want to see them in a full screen grid mode, tap the button the upper-right to go to the View All Presets page. There you can switch between Grid, List, and Detail view.

      3. The blue numbered buttons are for highlighting a box for a selected preset. Documentation covers this.

      4. You can use the search feature to filter your presets. You can add tags and edit the names of each preset from the View All Presets section. Note to save changes to a preset, long-press on a preset from the Presets tab.

      5. The green box around a preset is the currently active preset in MixEffect. If you don’t like that, you can disable it from MixEffect Settings > User Interface. There you can also enable the preference to show each box in a different color.

  7. I do events at different locations and who know what will happen with the internet at the venues. I do have an AP that has multiple ethernet ports. I use that router to connect to the internet and plug the ATEM Mini ISO and the ipad has a USB C dongle to have ethernet plugged in and sometimes as WiFi. What happens to the app if I loose internet from the hotel? Does the app still work since it is all communication thru the AP anyway? As redundancy, does the app work on hotspot 4g?

    1. If all devices are connected to the same AP/hotspot/router, you should stay connected to the ATEM with MixEffect.

  8. The App looks great however I am a bit confused re compatibility. I have an ATEM 2 M/E Production Studio 4K but this is not exactly listed in the documentation. You list ATEM 2 M/E Production Studio as OK but not the ATEM Production Studio 4K. You are running the app on iPhone or iPads but can it run on a new MacBook Air with M1 processor? Thanks

    1. MixEffect will work with the ATEM 2 M/E Production Studio 4K (will update the docs). It can also run on M1 Macs, but it is not officially supported (there are some UI oddities with the translation from touch to mouse-driven interface). More info on compatibility here:

      FYI: The initial list of switchers are ones that I have personally tested MixEffect on.

      1. Steve Thompson

        Adam, thank you for your prompt & precise response. I am off to purchase a MacBook.

  9. Hello Adam!
    Your MixEffect app looks like a great tool that solves a lot of field problems using the ATEM. I have three BM switchers at different locations. For my office setup, I have an ATEM Mini Pro ISO connected to one local network. I downloaded the MixEffect app and loaded it on an iPhone 10 and a 10.5-inch iPad Pro using software version 14.7.1. I am able to connect to my ATEM with the iPhone, but not with the iPad. Strange because I can use two other (way less powerful) ATEM remote apps on the iPad to control the ATEM Mini Pro ISO.

    I have a network background and I’ve checking in both English and Chinese language programing sources for reasons why this is happening. I followed your debug chart to the end and still no luck.

    I would be more than happy to get the app working on my iPad Pro. Can you give me any pointers on how I can correct this?
    Stay strong, safe and healthy.

  10. Why super sources does not appear in television studio hd pro?

  11. Hey Adam I love your app and all your presets in supersource. I’m wondering with the ability to crop video images ssrc would you be able to add in rounded corners?

    Thanks again

    1. ATEM Mini Extreme and Extreme ISO don’t have the ability to add a border around SSRC boxes. The ATEM Constellation 8K, 2 M/E Production Studio 4K, and the 4 M/E Production Studio 4K can. You can use the SuperSource foreground or background art to simulate rounded corners around your boxes though.

  12. Hi,
    I live in Algeria and I wanted to buy the app using a US credit card( belongs to the Entity where I work) using my apple ID with no success , each time I try I have this message ” you have to switch to apple local store unfortunately I don’t have a credit card issued in Algeria , is there a way to buy it directly from your website or anther way to buy it .

    1. I haven’t seen this error before. Can you send an email to me directly using the Feedback link in the MixEffect Settings with a screenshot of the error? I can see if Apple Support has any suggestions for you. The app is only available from the App Store.

    Hey Adam.

    Firstly, thanks, I love the app and the feature rich functionality.

    I have a question, which I have been struggling with over the past 2 days. I have loaded the trial version on both my iPad and M1 Mac Mini at the studio and have connected it to my ATEM 2M/E Production Studio 4K and trying to use your multiview presets within Companion. But it will not action the required custom formats that are available on the keys.

    Am I doing something wrong?

    Any help documentation or videos would be much appreciated.

  14. Gavin – I don’t have a 2 M/E Production Studio 4K to test right now, but I do have a 4 M/E Broadcast Studio 4K which has a similar MV setting. It looks like you should use the Generic OSC command: /mixeffect/multiview/layout

    The first parameter is one of the following four Layout values:

    4 = Program Bottom
    6 = Program Right
    11 = Program Left
    13 = Program Top

    The second argument should be the MV Index, 1 or 2, but in the current MixEffect 1.5.1 release, it doesn’t work (only MV 1 is changed). I will have this fixed in the upcoming 1.5.2 release.

    1. Gavin

      Thanks Adam.

      I am seriously feeling like a novice in this regard. It took me a few attempts to get the arguments right… which worked, but only one time.

      Every time since then, the bottoms just seem to have zero impact on the desk.

      I will keep trying, as it is not in my nature to give up… but I may just wait for the upcoming release of 1.5.2. in respect to the MV layout.

      Although I have to once again say that I am truly impressed with the overall app functionality, and have been using the SuperSource portion in our daily news type program.

      1. If you can send me an email with a screenshot of your Companion buttons, I can try to replicate what’s happening.

  15. Kim Holland

    My team and I provide environmental education lessons over Zoom and have utilized ATEM mini and OBS with a second laptop in the past. We no longer have an extra laptop available but do have an iPad. I’m interested in the Pro version of Mixeffect if it can switch the camera to an uploaded video. In the past, we had the second laptop connected to the ATEM mini and used OBS to become another ‘camera’, switched the camera selection, and manually hit play. I’m hoping the Mixeffect app can upload a video, then hit a preset button to switch the audience view from the speaker to the video and then play the video. Is this possible with your system? Or will there be another step in between?

  16. Kim: when you say upload a video, do you just mean playing back a video from the iPad? Would you primarily be using MixEffect to control the ATEM or will you be doing this mainly by pushing the buttons on the ATEM? There is no video playback capabilities in MixEffect, and the app can only upload still images to the ATEM. I recommend you look at the Live App Pro app – if I am understanding your question.

    If not, can you clarify again what it is you are looking to accomplish?

    1. Kim Holland

      Yes, that’s correct on playing a video back from the iPad. We will be using the MixEffect to control the ATEM and can accomplish all we need with the non-pro version other than playing videos. That clarifies what we can use MixEffect for, thank you!

      1. So this is possible. Live App Pro and MixEffect need to be running in Split View on the iPad, with Live App Pro on the LEFT side of the screen. This will allow Live App Pro to output the video through the HDMI feed.

        Keep in mind that if either app crashes (rare), if the ATEM is outputting the iPad, users might see the iPad screen. Just relaunch the two apps and you should be fine. Crashes are rare, but want you to be aware of that.

        What kind of iPad are you using? The one with the USB-C port? If so, I recommend connecting the iPad to power, Ethernet, and HDMI. The Lightning iPads you can only choose Ethernet + Power or HDMI + Power.

        Another alternative is to use an iPhone to control the ATEM wit MixEffect and use the iPad just for Live App Pro.

  17. Den yee

    What iPad do u recommend to run mix effect pro. I am using ATEM 2me constellation thx for u your help

    1. Any iPad Pro from 2018 to today will work well. I recommend any iPad with a USB-C port, including the iPad Air or the iPad mini 6th-generation.

      The new 10th-generation iPad has a USB-C port, but speeds are limited to USB 2.0 speeds, so I am not sure about that model. As for Lightning-equipped iPads, I would avoid used iPads that have processors older than the A12.

  18. Rafi Sheikh

    I have been uskng mix effect since it was rekeased. Has worked very well. Yesterday it would not do supersource-adjustment at all. Would not report audiolevels on any line input. Using atem mini extreme iso. It worked flawless last time I used same setup in september. Will do some more testing next week.

    1. Was it connected to the ATEM switcher? Did the IP address of the Extreme change in any way? That would have prevented it from connecting. Sometimes, the switcher needs to be restarted after a long time. Or, try disconnecting and reconnecting in MixEffect.

      1. Rafi Sheikh

        Hi, I now got a new Atem extreme iso now and Mix effect now it works as expected.

  19. Good evening Adam, back in October you helped me connect my atem to my iPad using MixEffect. Today when I attempted to connect my iPad I got a notice that I needed to purchase the pro version of MixEffect to access certain features. In error I repurchased MixEffect again. I need to cancel my new purchase and to find out why I am unable to use MixEffect Pro on my iPad which I purchased on the 7th October.
