Client-server playout solution for the Mac

OnTheAir Node has been designed to be an inexpensive, reliable and customisable video server that has an open client-server architecture. OnTheAir Node can be controlled remotely over the network. One client computer in a control room can control multiple OnTheAir Node playout servers located in the machine room.
With its unequaled openness, OnTheAir Node brings a new era to the world of Mac based playout servers. OnTheAir Node allows third party applications such as Traffic and Media Asset Management solutions to easily take control of a reliable playout server with real-time media cataloging and validation.
OnTheAir Node uses the same playout engine as OnTheAir Video.

Playout multiple channels on one Mac

With OnTheAir Node unequaled efficiency, you can playout 8 streams of HD simultaneously on one Mac. OnTheAir Node's Smart Playout Engine is the same engine as OnTheAir Video. It can play multiple streams on one Mac (without Dynamic Graphics Overlay, and streaming options).

Media Management and Validation

OnTheAir Node will not only output video to any of the available video output on the Mac, and allow it to be controlled remotely, but it will also catalog the available assets in one or more media folder and it will inform any of the client application (OnTheAir Live or OnTheAir Manager) when a new asset arrives or is deleted. It will also check for validity and compatibility. Information on the clips can be retrieved using a RESTful API, making it easy for any other third party application to retrieve the clip's characteristics. (Ex: video codec, audio sample rate, creation date, last modification date, finder label etc.)

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.
NDI® is a registered trademark of NewTek, Inc.

Integrate with third party solutions (Traffic or MAM)

OnTheAir Node’s open architecture will allow any third party application as Traffic or Media Asset Management software to control the playout and see the list of available media. OnTheAir Node uses a HTTP REST API for its communications meaning that the protocol is a proven and open standard that doesn’t need any special requirements.

GPI Control and Viderouter controls

Send GPI triggers from OnTheAir Node to a video mixer or any GPI compatible device to take control of it thanks to our GPICommander box which connects in USB to your Mac and provides 24 inputs and 8 outputs of GPI.


You can also control video routers very easily. Blackmagic-Design Videohub and AJA Kumo routers have a dedicated plugin that connects through the Network to take control of the crosspoints. That is with this type of control that our users handle Live events in their 24/7 playout.

Attributes for secondary events

Thanks to its flexible system of "Attributes", OnTheAir Node can take control of multiple external devices such as video routers (through RS232 or Ethernet), Character Generators, logo inserters (using GPI triggers). Attributes are changed for the whole length of a clip and reverted back to the default value at the end.


The logic of Attributes make it very easy to handle in broadcast operations. Attributes always have a default value (such as logo on, or GPI on), and you decide to modify the default value only on the clips you want (set logo off for commercials for example).

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.)

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).


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.

For Live or 24/7 unattended

If you are producing a live show, control OnTheAir Node with OnTheAir Live (FREE) to have a playlist type of application. If you are running a TV channel, control OnTheAir Node with OnTheAir Manager (paid option), it has a beautiful Calendar type of application where you can create events, playlists, handle redundancy, have attributes hierarchy and categories, add live clips. All that in a very easy-to-use application.

Add dynamic graphics with OnTheAir CG (option)

Combined with OnTheAir CG you can add Dynamic Graphics Overlay using the same video output (does not require an additional card thanks to the direct link between OnTheAir Node and OnTheAir CG). Create stunning dynamic graphics in the free OnTheAir CG Designer application, import it in OnTheAir CG Server to control from OnTheAir Node. You can give a default status to each project, 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.

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.

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.
