To implement an external update service, you need to parse and return a Vizrt Data Format (VDF) document to the Media Sequencer. The document is posted to the update service by the Media Sequencer.

Working with the data formats requires knowledge on how the data is structured when sent from the Media Sequencer to Viz Engine. You can do this by, for example, looking at the Media Sequencer’s console, and then work with the data that is sent.
Vizrt recommends that you contact your local Vizrt Support representative and obtain the current version of the VDF.

Example of a VDF Document

<?xml version="1.0" encoding="utf-8"?>
<payload xmlns="http://www.vizrt.com/types">
<field name="foo">
    <value>bar</value>
    </field>
    <field name="otherfoo">
    <value>otherbar</value>
    </field>
</payload>

Field Names refer to Field Identifiers, a property available to all Viz Artist control plugins.
