Viz Mosart User Guide

Version 5.1 | Published January 19, 2023 ©

Rundown Window

The rundown window displays a rundown/story list, corresponding to the content received from the NRCS.

The list can be modified at any time by updates from the NRCS, or by manual edits from a Mosart operator.

Each story line consists of a story info area to the left and the Viz Mosart templates and secondary elements extracted from Viz Mosart commands in the NRCS, to the right.


Story Info

The left Titles and Timings area (also called Story Info area) displays the following details:

  1. Top left hand corner: Estimated On Air time.

  2. Top right hand corner: The editorial duration of the entire story, as entered in the NRCS.

  3. Second line: The story title as entered in the NRCS.

  4. Timer in the middle of first line: When the story is On Air, how long the story has been running.

  5. Red marker: The story currently On Air.


    Yellow marker: The next story that will be taken to air.

Story Elements

Templates are represented in the right hand, timeline area of the rundown window using color-coded elements. The length of each element reflects the calculated or exact duration of the template, depending on the template type.

  • An identifier in the top left corner denotes the variant name of the template type.

  • A story using a recognized template type but an invalid variant displays the variant title in red:

  • When a story contains several elements with long duration, a vertical scroll bar appears to the right (one story will not display over more than four story rows in the Viz Mosart GUI).

  • Stories with no corresponding Viz Mosart commands appear as empty lines in the rundown window timeline.

The story elements are described in detail in the following sections:

Primary Story Elements

A story element corresponds with a Viz mosart template type. From each basic template type, a show designer creates clones with show-specific commands. Each clone is called a variant.


The Camera template type is displayed as a green colored element in the GUI. The variant of the template type (often the camera number) appears in the top left hand corner. The duration of the template is automatically calculated based on the presenter's script as entered in the NRCS (see Story Editorial Time below).



This template type is for playing (or recording) a video clip.
The package template type is displayed as a light blue element in the GUI. The variant identifier appears in the top left hand corner. The length of the package element is calculated from the actual clip length, if available on the video server.

Error Situations


  • If the package clip is not available from the video server , the template representation appears with a blue/red checkered pattern.
    Similarly, placeholder clips are displayed with a white/blue-checkered pattern.

  • Zebra-stripes mean that the video server has failed to cue clip for playing.



In some systems, Keyframe markers are displayed with grey semicolon markers:



The voiceover template type is displayed as a light blue and green element in the GUI. The variant of the template type is indicated in the top left hand corner of the colored element. The small notch in the green bar shows the calculated duration of the presenter text. The light blue represents the clip as with the server template type and the green represents presenter text as with the camera template type. If the clip is not available from the server, the clip section of the element has a checkered pattern.

The length of the voiceover element is calculated from the actual clip length when available on server.


Live/external Source

The live type is displayed as a red element in the GUI. The variant of the template type is indicated in the top left hand corner of the colored element.



The fullscreen graphics type is displayed as a yellow element in the GUI. The variant of the template type is indicated in the top left hand corner of the colored element. Duration of the element is timed from the presenter text entered in the NCS. For graphics systems which support this feature, the element has a checkered pattern if the attached graphics content is not available for playout from the graphics system.


Note: If back-to-back fullscreen graphics are within in the same story (and use the same engine), the scene is not retaken for each graphic, but just kept playing. As the show advances, and one story is left, a new story entered, the graphics are taken again (i.e. the engines are ejected) so that any other graphics that are using the same engine are taken normally.

Digital Video Effect (DVE)

The DVE type is displayed as a yellow and red element in the GUI. The variant of the DVE template type is indicated in the top left hand corner of the colored element.



The telephone interview type is displayed as a yellow and white element in the GUI. The variant of the template type is indicated in the top left hand corner of the colored element.


AdLib Pictures/Floats

The ad lib pictures template type is represented by a symbol at the right end of the story line in the rundown window. If the associated media object is not on the server, the symbol is checkered.


The element also appears in the Assets window as a colored slug with a green top half and light blue bottom half for clips, and orange bottom half for graphics. They can be taken On Air or to preview either by right clicking and using the context menu in the rundown window or the Assets window.

Adlib picture templates adds the audio faders specified in the template to the current audio fader set. The faders are subtracted when returning from the Adlib pictures. Adlib pictures are typically used in live external or studio interviews.

Adlib pictures pause when it is taken Off Air. If the Ad lib pictures is inserted again the clip continues from the paused point.


The break/continuity template is displayed as a white element. The break story is the default start and end-point of the show from which total show timers are made. Break templates can also be used for commercial breaks, when master control takes over.


Other Primary Templates

  • Jingle

  • Video Wall

Secondary Story Elements

Overlay Graphics

Overlay graphics (lower thirds) are shown as a yellow secondary element. Secondary elements appear on top of primary elements and are executed relative to the primary template. The secondary element is scaled to the duration of the lower third element set in the NCS.

Different types of overlay graphics with separate handlers in the Overlay Graphics application, such as lower thirds, wall elements or OSGs, can be displayed in different lower third level.

See General Settings for details on setup.

Take In

Take-in of lower third elements may be performed either manually or automatically from Viz Mosart.

  • Automatic: If an in-time is set in the NCS for the lower third Viz Mosart automatically takes it in.

  • Manual: If no time-in is set in the NCS for the lower third, Viz Mosart marks it as a manual lower third. These elements are displayed on the right hand side of the GUI window, and can be executed in the same way as adlib pictures.

Take Out

Take out of lower thirds may be performed in four ways. These are displayed differently in the Viz Mosart GUI:

  • AUTOOUT: Is taken in and taken out automatically from the in-time and duration or out-time set in the NCS

  • images/download/attachments/81487235/userinterface_overlay-manual.png BACKGROUNDEND: Is taken in automatically as defined in the NCS and taken out with the primary element it is attached to.

  • images/download/attachments/81487235/userinterface_overlay-storyend.png STORYEND: Is taken in automatically as defined in the NCS and taken out when the story it is attached to is taken Off Air.

  • images/download/attachments/81487235/userinterface_overlay-backgroundend.png OPENEND: Is taken in automatically as defined in the NCS and is not taken out before the operator takes it out.

Audio Play

Audio Player secondary elements are displayed as a small speaker symbol on top of a primary template. Its position represents the time code given in the NCS. The audio starts to play when the timeline reaches the position. If no in-time is defined for the sound it appears as a manual element in the symbol in the right hand area of the rundown where manual lower thirds and adlibs are shown.


Accessory Elements

Accessory secondary elements are displayed as a small plus (+) icon on top of a primary template images/download/attachments/81487235/userinterface_secondary-accessory.png .

There are two ways to use an Accessory. This relates to how they are taken:

  1. Automatic: (timecode driven) The element's display position represents the timecode provided in the NRCS. The Accessory item is taken when the timeline reaches the accessory icon.

  2. Manual: If no in-time is defined for the Accessory item, it is displayed as a manual element, with its icon to the right of the rundown, similar to where manual lower thirds and adlibs are displayed.

Color coding

Black background: Normal, the element is available.

Red background: The accessory template does not exist/is unavailable.

Additional Rundown Features

Story Editorial Time

The story planned duration (editorial time) entered in the NRCS is indicated by a grey marker on a story element or after the last story element.


Autotaking an Element

If a primary story element is programmed with "autotake next" this is indicated at the end of that element with a black triangular symbol.
Any element e1 following immediately any element e2 based on that template, will be taken automatically when e2 is 'finished'.


Effect Transitions

If an element is set to use an effect transition (from the NCS or the Template Editor), this is indicated with a black and white symbol.


Timing Information

At the top of the rundown window, there are indicators at every 30 second mark. Vertical lines running down the rundown window indicate every second, and broader lines every ten seconds.


Mouse-over Rundown Info

Hovering the mouse pointer over an element in the rundown displays the NCS script and timed commands connected with that element.

In this example, mousing over the Camera 1 element displays the transition which is used going into the template - a four frame mix - and the template variant “1”. In addition, we can see the entire script written into the NCS story connected with this template, and the details of a secondary accessory template element.
