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. Overlay buttons are shown depending on the playout status, once the mouse is over the Preview or On Air window. At the bottom of the Control Area system relevant information is shown, like the Engine Buffer Status and the Channel Status.

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.
On Air: Shows the On Air signal including video and graphics and the relevant control buttons as overlays, in case the mouse is over the window. 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. In case CC or OP-47 VANC data is inserted into the SDI signal, a corresponding label is shown here.
Status: Shows the engine buffer level and the Channel status.
Buffer
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.
Timeline
The Timeline shows all elements which are loaded in one of the available layers 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.

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. In case a Rule is defined for this channel, a symbol is shown to indicate that a Rule is active.
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.
