How to add subtitles to an Item [VC UG]
Vidispine supports adding subtitles to an item and to do so, the metadata field group stl_subtitle must be used. The group should be placed within a timespan corresponding to the in- and out timecodes for when the subtitles should be displayed.
Example;
<MetadataDocument xmlns="http://xml.vidispine.com/schema/vidispine">
<timespan start="10@PAL" end="100@25">
<group>
<name>stl_subtitle</name>
<field><name>stl_justification</name><value>left</value></field>
<field><name>stl_vertical</name><value>6</value></field>
<field><name>stl_text</name><value>some text actually two lines</value></field>
</group>
</timespan>
</MetadataDocument>
