4.1 Control Area & Timeline (v3.0)

Control Area

The Control Area allows you to preview the item which is currently selected in the Workbench/Timeline (shown in the PREVIEW window) and it shows the final output signal (shown in the ON AIR window) which is sent to the Video output device. In addition it shows some system relevant info.

  1. Tab view (not shown on screenshot): Shows the Multi Viewer as well as all the opened Channels you are currently working with, which allows you to switch to a different Channel.

  2. Preview: Shows the selected Video, Audio or GFX element. Click the play button in the viewer to start the preview of the element, or to release the stop frame of a graphics element. Click the speaker symbol to toggle the ability to preview the audio.

  3. On Air: Shows the signal including video and graphics. In the upper right corner there are two elements to control the Audio Bars and Timecode overlays shown on top of the On Air window and which allows you to turn the Audio Monitor on/off.

  4. Engine Status: Shows the engine buffer level and the temperature (if available) of the CPU running the just:out engine.


  • Green: Good buffer status.

  • Yellow If the buffer status is below 50% it must recover to green in time, otherwise the Playout will stagger.

  • Red: The engine's buffer is completely empty and the output will drop frames or even stall completely.

CPU Temperature of the machine running the just:out Engine

  • Green: the temperature is fine.

  • Yellow: the temperature is slightly too high, the Playout may stagger if the temperature rises even more.

  • Red: the temperature reached a critical level and the Playout will drop frames or even stall completely.

In case the temperature of the machine running the engine is to high, the operating system will reduce the speed of the machine or shut down certain functions completely. Please contact your system administrator in case the temperature indicator reaches the red level during normal usage.


The Timeline shows all elements which are loaded in one of the available layesr of the Channel but also those elements which are already playing out. This includes the element names, the elapsed/remaining time info and the' "Play" button. The visibility of the final output is defined from top to bottom.

  1. Layers: Depending on the configuration the Channel you will see Audio, Event, FX- and Video-Layers. The names of the Layers may differ from the ones seen in the figure above, as they have been defined by your system administrator while setting up the Channels. It is also possible that your Channel has more or fewer Layers than shown in this figure or that certain Layers do not exist at all. 

  2. Elapsed Timecode: Displays the elapsed time for each actual playing element. If a Layer does not contain any elements the timecode is 00:00:00:00.

  3. Current Item Name: Displays the name of the current item in the particular Layer.

  4. Poster Frame: Shows (if available) the poster frame of the current item in the particular Layer.

  5. Current Time Indicator (CTI): Shows the current Playout position.

  • Yellow: The just:out engine is not started.

  • Green: The just:out engine is started.

  • Red: The just:out engine is started, but there is an FX element waiting at a stop frame.

6. Content of the Timeline:

  • Audio Element: Audio elements are represented by grey bars (or slices, depending on the Timeline scale). Audio items can only be placed on Audio Layers.

  • Graphic Element: Graphic elements are represented by grey bars (or slices, depending on the Timeline scale) with a gray triangle in case it has at least one stop frame in it. Only FX Layer compatible files can be placed on FX Layers.

  • Event Element: Event elements are represented by a yellow triangle. Event items can only be placed on Event Layers.

  • Video Element: Video elements are represented by grey bars (or slices, depending on the Timeline scale) in the Video Layer. The bright blue part represents a finished action or loop.

7. Remaining Timecode: Displays the remaining time for each actually playing element.

8. Hide/Show Buttons: Toggle the visibility of the currently playing element(s) on the specific FX Layer. The visibility of hidden Layers can be changed in the menu View → Hidden Timeline Layers.

9. Timeline Scrub & Scale: The scale of the Timeline ruler can be changed by using your mouse wheel while hovering above the Timeline's ruler. The Timeline can either be static or rolling (View → Static Timeline). In static mode the Timeline ruler description starts with zero, in rolling mode the description equals the engine time.
