Viz Trio User Guide

Version 4.1 | Published September 25, 2023 ©


The following terms are used for Trio:

  • Control Plug-ins: A graphics scene can contain all sorts of objects that can be controlled from a template such as text, back plates, images, colors and more. The graphics designer uses control plug-ins to expose objects as tab fields.

  • Control Object: Every scene with control plug-ins must have one instance of the control object plug-in at the root level of a scene tree. Control Object reads the information from all other control plug-ins. When a scene is imported to Viz Template Wizard, it reads the information about other lower level control plug-ins through Control Object.

  • Forked Execution: With the new profile configuration, Viz Trio now supports forked execution by having more than one graphics render engine per channel. Simply put, you can trigger the same scene on multiple render engines where one can act as your backup.

  • MAM-system: A Media Asset Management (MAM) system takes care of ingestion, annotation, cataloging, storage, retrieval and distribution of digital media assets. Viz Trio works together with Vizrt’s MAM-system Viz One.

  • Newsroom Component: In a Newsroom Computer System (NCS), the Newsroom Component (NrC) is used to add data elements to a story. The user is typically a journalist working on a story. The NrC is an embedded application in the NCS that connects to a database of templates. The templates can be filled with text, images, video and maps.

  • Page: A page is based on a template and saved as a data instance of the template. A page contains a set of data and references to where data (e.g. images and video clips) can be found. When a page is loaded, all static elements will be loaded from the template and the variable elements (items/tab fields) will be set to what they were when the page was saved. Therefore, a page is not saved as a complete scene. It is only the values of the tab fields that are saved together with a reference to the template-scene.

    Note: Only pages can be taken On Air.

  • Scene: A scene is built in Viz Artist. It can be a single scene, or one part (layer) of a combination of scenes (transition logic).

  • Template: A template is based on a Viz Artist scene, and is created by Viz Trio on-the-fly while importing it to Viz Trio. The template is used to create pages that are added to a show for playout. A template can be based on one or several (transition logic) scenes (known as a combination template).

  • Transition Logic Scene: A set of scenes built in Viz Artist. A transition logic scene contains one scene that controls the state of or toggles a set of scenes (layers). The layered scenes are used by the controlling scene to toggle in and out the layered scenes, using pre-configured or customized transitions effects, without the need to take scenes already on-air, off-air. For example: A lower third may be on-air at the same time as a bug, and the lower third may be taken off-air without taking the bug off-air or reanimating it.

  • Viz Artist: The design tool where the graphics scenes and all animations are created.

  • Viz Engine: The render output engine used for playout of graphics and video.
