The Graphics Preview window is located to the right in the Template Builder. It displays snapshots of the final output in an ongoing preview process, and provides you with an idea about how the graphics will look when played out in high resolution on a Viz Engine.

The Template Builder sends requests to the Preview Server which manages Viz Engines that provides the snapshots.

The toolbar at the bottom of the Preview Window allows you to adjust how to view the preview of the element graphics:

• Preview points: If the scene contains named preview points, such as stop points and/or tags in the Default director, these are shown as buttons on the toolbar. If there is not enough space for the buttons, they appear in a drop-down list instead. Pressing the buttons or selecting an entry from the drop-down list shows a preview of the scene at the given preview point, and the playhead on the timeline jumps to the point in time where the preview point is set.

• TA: Show/hide the Title Area.

• SA: Show/hide the Safe Area.

• K: Show the key signal for the graphics.

• Load: Clicking this button will load the animation of the graphics. Once loaded, indicated by a green line at the bottom of the timeline editor, media controls appear allowing for controlling the graphics animation in the Preview Window.

• Scrub the timeline back and forth by clicking on it or moving the playhead. If the scene does not have a director called Default, or the Default director does not have a duration the timeline will be disabled. Setting the minimum duration in Template Builder will enable the timeline. Setting the default duration in Template Builder will change the duration of the timeline if it is enabled.

  Info:

  Clicking on a preview point to request a preview sends a snapshot request with a named position to the Preview Server. Clicking on the timeline sends a snapshot request with an absolute position to the Preview Server.
