Open and powerful playout solution for the Mac

OnTheAir Video can be used for automated playout using its own scheduler or it can serve as a clip store for live news operations, local broadcast or live shows. Schedules can be created weeks in advance.

Thanks to its powerful Smart Playout Engine, OnTheAir Video supports multiple video formats such as Apple ProRes®, AVC-Intra®, Avid DNxHD®, H.264, HEVC, MPEG-2, MPEG-4, MPEG IMX, XDCAM EX, XDCAM HD, etc... You can add multiple transitions between the clips (cross fade, wipe,...)

With the Dynamic Graphics Overlay option, you can overlay dynamic graphics on top of your video very easily.

Mix-and-match multiple codecs

Play multiple codecs, file types, formats and frame rates in the same playlist. Support for Apple ProRes®, AVC-Intra, Avid DNxHD®, H.264, HEVC, XDCAM and many more codecs. Multiple file types are supported: movie files (such as .mov, .MXF, .M2T, .M4V), still images or sound. (Check the list in the Tech Specs section.)

Dynamic Graphics Overlay

Create stunning dynamic graphics in the free OnTheAir CG Designer application, import it in OnTheAir Video and select when you want it to play in your playlist. You can give a default status, and change variables, so for example if you need to add coming next, you can have just one project and just modify the text and the image used.

Support for 8bit, 10bit and ARGB

Use YUV 8bit, YUB 10bit or ARGB pixel formats to match your needs. Depending on the output that you use, you will be able to select these pixel formats. When outputting to ARGB, if the device allows, we'll output both the fill and the key signals.


Add transitions to bring even more dynamic to your playlist. You can use either built-in transitions such as cross-fades, or custom transitions (made with your own movies with an Alpha Channel).

Secondary Audio Output

Additionally to the video output on the selected video device, you can now also output to another available audio output on your Mac. Works with CoreAudio, so supports the audio devices that are available for macOS (including Dante or MADI).

Schedule your Playout for 24/7 unattended playout

OnTheAir Video is in use by many TV stations worldwide as their main automation software. Thanks to an easy to use scheduler, you can schedule playlists to be played automatically at given time of days. Prepare your playlists and schedules in advance and let OnTheAir Video do the rest. OnTheAir Video can play 24/7 for days and days without having to worry about it.

Remotely Controllable

With the "Remote Pack" option for OnTheAir Video, you can use a simple web browser on another computer, or another OnTheAir Video to control your playout remotely. The option also adds a "Media Browser", which lists all the media available for your OnTheAir Video, so you can see remotely what clips are available for playout.

Actions for secondary events

Thanks to its flexible system of "Actions", OnTheAir Video can send SCTE35 triggers, overlay dynamic graphics (with the DGO option), control multiple external devices such as Character Generators, video routers, logo inserters. Actions can be triggered at any moment of a clip within a playlist. Actions are AppleScripts, so it is very easy to customize them and create macros to perform multiple controls with a simple action.

Subtitling and SCTE35

OnTheAir Video is a simple to use software, but with advanced feature such as the support for subtitling (Closed Captioning CEA608 or CEA708 and OP47). You can embed the subtilting in the file, or use a SRT sidecar file.
The support for SCTE35 is very useful for add-insertion programs. You can either embed the SCTE trigger in your MXF file, or tell OnTheAir Video to trigger the SCTE35 at a specific moment of a clip using Actions.

Supports NDI® Output

NDI® is an open, low-latency, video-over-IP protocol developed by NewTek, Inc. It uses a simple gigabit ethernet cable to transmit video and audio over a local area network between multiple video systems. Now, thanks to NDI®, you can transfer HD and 4K video over a simple Ethernet cable. There is no need for additional routers or even SDI cables anymore, further demonstrating the ease-of-use and reliability of our products. NDI® opens the world to a different way of doing video production and to an ecosystem of devices supporting the protocol.

Stream on the same Mac

If you are a Web-TV broadcasting only to the web, you will love this feature. With OnTheAir Video and the Softron Streaming Pack in MovieRecorder, you can stream your video directly to YouTube, Facebook, Twitch or your Wowza or RTMP Server. No need to have a video output device.

Integration with traffic software

You can use the built-in scheduler to create your schedule and playout 24/7 unattended, but if you want to use your traffic solution to control OnTheAir Video, add the "traffic" option. Create your playlist (or log) in your traffic solution, such as Wide Orbit, and OnTheAir Video will import it and play it out. The traffic option includes the "Remote Pack" option.

Buy or Upgrade

Make sure to test with our free DEMO version available for download before purchasing so you are sure it fits your need. In DEMO mode, the application will burn a blue frame in the recorded file or at output at some intervals. That's the only limitation and difference. After your test, you will keep on using the same application, just with the demo mode unlocked.


Purchase one option per channel (except for the dongle which can hold up to 20 licences on one dongle, and for which it's one dongle per computer)

Important Note: Some of the codecs above such as H.264 or MPEG2 can have a lot of variants. This is why we always recommend to have a procedure on how to create the files you put on air. So you are sure it will always behave well. If you receive files from external sources and you don't know how they were generated, it's always a good idea to test them before putting them on air. You can even test them on a different computer with a demo version of one of our playout application.

About these specifications

We know that some of our users can not upgrade their macOS very often. This is why Softron tries to maintain compatibility with older versions of macOS as much as possible, but it is not always possible to achieve. Because Operating Systems are usually significantly improved over previous versions, Softron must use many of the more capable built-in functionalities inherent in Apple's latest OS releases. Failing to do so would mean that Softron software would essentially be blocked from using the new Frameworks provided in the OS. For this reason, Softron's free support is provided only on the current and previous macOS versions. Also, most of our tests will be done on these macOS versions, and only basic tests will be done on the previous OS. We will always try to help, but in some cases, the best solution is to upgrade your macOS to a more recent version.

Softron does not warrant that these recommended configurations will always meet specific user requirements. They are intended as guidelines and are based on extensive testing that Softron has done, they can be changed without notice. Hardware, drivers, software and operating systems change regularly and we advise users and prospective users to evaluate their requirements in their specific environment/workflow using Softron demo licenses that are available for downloading from Softron's web site.

Useful Resources

Limitations of the free DEMO mode

The free DEMO mode of OnTheAir Video 4 is fully functional for all features, except for the traffic option which require a temporary serial to be tested (contact us if you want to test it). Appart from it, the OnTheAir Video version that you test is the same that you will be using when you get your license, it just outputs blue demo frames every few seconds when in DEMO mode.

Installation instructions

Download the SINGLE version if you just need to play on one output, the Multi version to be able to play up to 8 streams on one Mac. Once downloaded, unzip the file, and drag and drop either the single application or the multiple applications folder in your "Applications" folder.
Warning! Do NOT run OnTheAir Video from your downloads folder or it will be quarantined. Always drag and drop from the Downloads folder to the Applications folder before using it. Make sure also to download and install the drivers for your video device:

AJA Drivers
Blackmagic-Design Drivers
Deltacast Drivers
For Intel and Silicon

Accessory Software

If you have the Dynamic Graphics Overlay option, you will also need OnTheAir CG Designer. You do not need a license to create CG projects to be used in OnTheAir Video DGO option. Download OnTheAir CG Designer here:

DEMO Limitations

In DEMO mode, the application will burn a blue frame in the recorded file or at output at some intervals. That's the only limitation and difference. After your test, you will keep on using the same application, just with the demo mode unlocked.

How to unlock the DEMO version ?

Purchase a license through one of our resellers or the Softron online store, then just activate your serial number in the License window or plug your dongle in the computer.

Upgrade/Update instructions

Just download the latest version and replace your previous version. It is always recommended to run extensive tests with your specific workflow and setup before putting a new version in production. You can use a free demo version for that on a separate computer. Previous legacy versions are available from the general downloads page.

You do not need to deactivate and reactivate your serial number when updating your Softron software. Read the following article to know when to deactivate.
