What's new in OnTheAir Video 4 & OnTheAir Video Express 4

Warnings and Important modifications

OnTheAir Video Express and OnTheAir Video

  • Playlists: Once you have saved your playlists with OnTheAir Video 4, if you try to open them with OnTheAir Video 3, a copy of it will be opened and you will have to save it again. The reason is that there are new "attributes" that don't work anymore (such as Comments, graphics items, transitions, etc...)
  • The playback preferences are different than the one of OnTheAir Video 3. So if you switch from one to the other, make sure to change them (which video device is used and the format) in both versions.
  • When starting OnTheAir Video, it will now show a warning: "Full Disk Access is not enabled". This is not mandatory, but it helps to have less warnings when OnTheAir Video need to access video files in your storage.
  • Changes in the playback start times in chain mode:
    • when the playlist is playing, and the "auto-update start times" option is enabled, the duration of the offline files will not be counted in the start times, so you will know exactly when the following clips will start.
    • after a clip was started, it will keep the time at which it started playing.


OnTheAir Video ONLY

  • The Schedule file is no longer a .txt file, it is now a XML file by default. The 'old' .txt file will automatically be converted to a XML. If you are using a third party tool to create your Schedules, .txt schedules can still be imported, but changes made to it in the user interface will only be saved to the XML. We advise you to change to the new XML format (JSON is also supported). Contact us for more info and help.
  • The as-run-logs have been moved by default to the same location as the technical logs. The reason is we wanted to have one less window asking to get access to the "Documents" folder. If you had a different folder set than the default one, it will be maintained there, but if you did not modify the default location, they will be moved.
  • As there is no installer anymore, this implies that:
    • Actions Folder has now moved to "/Library/Application Support/Softron/OnTheAir Video/OnTheAir Video/Actions/". It is not located next to the application anymore. We will copy your current actions to the new location, but we will not delete them from the current location so if you still use OnTheAir Video 3 this will still work. But remember this if you want to modify the Actions later to look in the correct location.
    • OnTheAir Tools is not installed by default (it's not needed to create schedules anymore, only for the "Log analyser" tool, so it can still be downloaded from our website.
    • AppleScript examples are not installed (the ones to be used as Actions, or to control OnTheAir Video). They can be downloaded from our website. 



  • There is no installer anymore. Just drag and drop the application to the Applications folder. 
  • Scrubbing in long GOP video clips in the inspector has been improved.
  • 4K decoding performances improvement
  • Improved remote editing of playlists and schedule. Now when you edit the xpls playlist document from another computer, OnTheAir Video will properly reload it, even if it is currently playing. If the currently playing clip is deleted from the playlist, it will stay in the playlist, keep on playing, and be removed from the playlist once done.



New features

OnTheAir Video Express and OnTheAir Video

  • Automatic Folder-based Playlist: Select a folder with media files, and OnTheAir Video will automatically populate the playlist with the content of the folder. Add a file, it will be added to the playlist automatically. Delete a file, the file will be removed from the playlist.
  • Shuffle playback: As with music playlists, the next clip will be randomly played.
  • Rename clips: Sometimes your file names are cryptic, now you can rename the clips in the playlists, so it says something more obvious. Also useful if you have split a clip in 2 with two different parts.
  • Auto-update modified clips: If a media file has been modified (replaced or deleted in the Finder for example), it will automatically update in the playlist.
  • New "Clip end behaviour": Cue next clip.
  • Added the ability to select a clip to "Play next", so OnTheAir Video can chain to any clip in the playlist.
  • Added an "auto-cue" feature. When using the cue mode, the next clip will be automatically cued after a specified duration.
  • Added the ability to add "Comments" in a playlist.
  • Added the ability to Disable Clips, so they don't play but remain in the playlist for later use.
  • Added support for new codecs: DNxHR and AVC-Intra 200
  • Added the audio countdown announcements. Get a voice telling you when the remaining time is 30, 20, 10, 5, 4, 3, 2.
  • New controls in inspector timeline
    • Right-click on the "Current Position" field to select if you want to display the clip timecode or the elapsed time.
    • Enter a TC in the "Current Position" field to go to that position.
    • Enter for example +3000 to go 30 seconds forward the current position. Or -25 to go 25 frames backwards.


OnTheAir Video ONLY

  • 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).
  • New Scheduling features:
    • Schedule editor is now in the application. With the ability to group playlists in "Events".
    • Repeated events. If you have a schedule that is the same every week, this will make your life easier. Repeated events can be disabled in case you just don't want them to run temporarily.
    • Scheduled playlists can now be automatically randomized when opening, or playback shuffled.
    • Schedule window: Automatically filter to show only the events of the current day.
    • Schedule window: You can choose which columns to display. This is important mainly for the start times and durations shown:
      • Theoretical Start Time and Durations (shown by default): include the duration of offline clips, as well as the preset duration of the playlist. This is used to display what will be the duration and start times of playlists once all the clips are online, and the playlist expected duration is met. This is for macro scheduling, ahead of time.
      • Real Start Time and Duration (can be shown with a right-click on the columns): only include the duration of the clips that are online.
    • If the Schedule is modified by a third party application, it is automatically reloaded. There is no need to "Reload" the schedule manually anymore.
    • Added the ability to "Loop" an event => you can loop multiple playlists.
    • Added the ability to set a preset duration to a playlist, so you can know if you are having overrun and underrun
    • Added the ability to add a timed start of a clip in a playlist directly. Set its auto-start date/time, and if the playlist is opened, it will start playing at the specified date/time. 
  • Validation report: Generate a report for a playlist to print (with offline clips, offline actions, ...). This is very useful for long playlists, to have a quick overview of possible issues.
  • Built-in CG:  (Requires the Dynamic Graphics Overlay Option) Additionally to still images, you can now import CG Projects in OnTheAir Video to be overlaid on top of the video playback. 
  • Transitions:  You can use either built-in transitions such as cross-fades, or custom transitions (made with your own movies with an Alpha Channel)
  • Streaming input: Supports HTTP, RTMP and TCP video input to play a web stream easily. Just add a "stream clip" to your playlist, enter the HTTP, RTMP or TCP url and start playing it back. Stream clips can be previewed in the inspector. You can either use a "real" live signal, and even play a VOD file from a web server.
  • Improved Actions
    • Actions can now be relative to the start, end, in, or out point. This is very useful if you need to start an action X seconds before the end of a clip.
    • Actions can now have a "custom" icon (instead of the standard A). This helps to better identify what kind of action has been added. 
  • Countdown until next Live event: In the "Timer" window, you can now show how long there is until the next live event
  • Support for OP47 Subtiltling. (Requires the CC option). It is supported either in an MXF file with OP47, or using SRT or .STL sidecar files.
  • Support for .SRT sidecars files with Closed Captioning. (Requires the CC option)
  • Support for SCTE-35 triggers. (Requires the CC option)
