A Mosart control command can be triggered from a template, executed when the template is taken (Command On Take), at continue points (Continue Points) or when the template is taken out (Command On Take Out).

Note:

A Mosart template can trigger multiple control commands.
A (not-templated) control command can trigger a Mosart template, often used for a DirectTake template.

Working with Control Commands

This is done through AV Automation > Devices > Template Editor > Template > Properties > Control Commands tab.
images/download/attachments/154391859/cComm.png

The figure above shows a single (video) control command to be executed when the template is taken. Multiple control commands can also be assigned here.

It is also possible to assign control commands to be executed at continue points and when the template is taken out.

The latter has limitation since the Parameter setting is not available. In this context it may be useful to trigger a direct take at this place.

Adding a Control Command

To Add a Control Command

Click the Control Commands tab in the Template properties window.
The three categories of control command are Commands on Cue, Command On Take, Continue Points and Command on Take Out.
Refer to the table Command Values and Parameters for command details.

Commands on Cue

You can recall control commands in Preview, when the template is cued. This enables triggering of events when a story item is taken to Preview.
images/download/attachments/154391859/cOT.png

As illustrated above, you can give the command a Value and a Parameter in the same way as for Command On Take, Command on Take Out.
Also, in a similar way to Continue Points you can set an offset for when the command is to be executed.

Note: For Cue commands, all offsets are relative to the start of cueing. This differs from Continue Points, where each offset is relative to the previous continue point.
In the illustration above, the User Message (Ready) will be sent 100 frames after cueing.

By defining a Newsroom tag as a parameter for an On Cue command, the user can set the parameter from the NRCS.

In the Parameter column right-click and select either Add/Remove/Change a newsroom tag .

Command On Take

When selected, the commands inserted in Control commands Take are executed when the template is taken to Program or On Air.

By defining a Newsroom tag as a parameter for an On Take command, the user can set the parameter from the NRCS.

In the Parameter column, right-click and select either Add/Remove/Change a newsroom tag .

Tip: This selection then appears in the Mosart Web App NRCS Plugin (or the legacy ActiveX Plugin) for adding the template to a rundown.

Continue Points

When selected, the commands inserted in Continue Points will be taken when pressing TAKE NEXT (default: F12). Viz Mosart executes this continue point from within the primary template in which it is inserted. Each line represents a new Continue Point.
images/download/attachments/154391859/autoT.png

Cue Next Item Index: Enter the line number (for example, 0, 1, 2, 3) of the continue point that executes a cue for the next/following Primary object. If empty, Viz Mosart cues when entering the last continue point in the list.
Autotake: Insert the autotake time, in frames. The command is then automatically taken after that time.

Note: For Continue Points, all offsets are relative to the last Continue Point. This differs from Commands on Cue, where each offset is relative to the start of cueing.
In the illustration above, the Device Property is fetched 20 frames after being taken on-air, Player Status is fetched at 50 frames later and from the NRCS, the Stop Status at 110 frames after the previous (Get Player Status) Continue Point was processed.

By defining a Newsroom tag as a parameter for a Continue Point, the user can set the parameter from the NRCS.

In the Autotake column right-click and select either Add/Remove/Change a newsroom tag.

Tip: This selection then appears in the Mosart Web App NRCS Plugin (or the legacy ActiveX Plugin) for adding the template to a rundown.

Command on Take Out

The commands inserted here are executed when the template is taken from the program, taken Off Air, or at the end of the template. Only a single command can be used in Command On Take Out, and it does accept any parameters.

Command Values and Parameters

Note: Parameters marked with (*) do not work for templates.

Note: It is not possible to enter a Parameter in the Control command Take Out section.

COMMAND	Value	Parameter	Description
ACCESSORIES	TAKE_NEXT	(*)
AUDIO	FADE_MANUAL		Toggle fade manual.
	FADE_OUT_KEEPS	Fader rate	Faders that are set as "keep level" in the template On Air are faded out. Will also work when new templates have been taken in between the 'keep' action and the FADE_OUT_KEEPS.

The operation will be performed at next transition. <empty>: (no value entered) The second level for faders in the template in Preview are set to TOGGLE their current state. Note: A blank command parameter is a toggle function, and is therefore NOT suited for use from a template.

FALSE: All sound faders respond to commands from templates. <empty>: (no value entered) All faders are set to TOGGLE their current response state (default).

Parameters with Placeholders

Control command parameters can include placeholders which are then populated with values found among the fields of a currently On Air, Viz Mosart item. A placeholder is defined as a string of characters, within curly brackets {placeholder}.
For example, a placeholder can be useful for transmitting values from the NRCS, for use as control commands that will be executed when the template is taken On Air.

Example: Providing the clip name to be recorded from NRCS.

In the NRCS, a column can be created for giving the name of the clip to be recorded with Viz Mosart. Then, in Viz Mosart Newsroom settings, map the column in Story External Metadata as follows:

Story External Metadata

<mostag mostagname="NCScolumn" mosart_action="item_variable" action_value="NCS_filename" format_type="String" />

In Manus file, the Mosart item will have the following fields (the value Clip1 is given from the NRCS):

Mosart Item

<fields>
     <field name="NCS_filename" value="Clip1" />
</fields>

Then, in Template Editor, the control command for the respective template is configured as follows:

Control Command

RECORD PREPARE {NCS_filename}_Test,Recorder,RecPort

When the template is executed, a clip with name Clip1_Test is prepared for recording.

Examples

Value	Parameter	Description
PREPARE	TestClip,Default,R	Prepare a clip with name TestClip on the Default recorder. The Default recorder will be using video port R. For Quantel this clip will be initiated using the default duration.
PREPARE	TestClip,Default,R,1500	Prepare a clip with name TestClip on the Default recorder. The Default recorder will be using video port R. For Quantel this clip will have an initial duration of 1500 frames = 1 minute (25 frames/sec)

START	,Default	Starts the recording on the Default recorder. Note: There is a leading ‘,’ in the Parameter
STOP	,Default	Stops the recording on the Default recorder Note: There is a leading ‘,’ in the Parameter

The options in the Value dropdown are

PREPARE
START
STOP
STOP_AND_DETACH
DELETE.

The Parameter should be a comma-separate list of up to four items:

ClipName
Recorder
PortName
Duration.

If all four items are present, the Parameter will be

<ClipName>,<Recorder>,<PortName>,<Duration>

RECORD: Syntax

If not all items are present, any commas to the left of present items will still have to be present.
For example, if only Recorder is present, the syntax is:

,<Recorder>

In some cases, the ClipName item may have sub-items. In that case, the sub-items are separated by semicolons. (An example is given below.)

Here the options in the Value dropdown are explained in more detail:

PREPARE: Viz Mosart will prepare a clip for recording.
- Parameter: <ClipName>,<Recorder>,<PortName>,<Duration>
- ClipName: The name of the clip to be created
- PortName: The name of the video port where the recording shall take place. Note that this port has to be part of the 'Rec' virtual video port group.
  
  Note: For the setup of recording ports, please refer to The Viz Mosart Administrator Guide. See also Recording in the Viz Mosart User Guide.
- Recorder: A user-defined name to be used for the recording, tied to ClipName and PortName. Used by START and STOP.
- Duration: Estimated duration of the recording in frames.
START: Viz Mosart will start a recording previously PREPAREd
- Parameter: ,<Recorder>
  
  Note: Note the leading comma as explained above.
- Recorder: Name of recording session as created by PREPARE
