A track can be set as "master".

When a track is marked as master, a crown is displayed as icon.

 

Master tracks are used as templates or references in the project.

 

There are several advantages with master tracks.

 

•Some dialogs can automatically select the master track as source. This saves time.
For example, the comparer tool automatically finds the master track.

 

•Master tracks can inherit subtitle properties to subtitles in "vassal" tracks, such as, raised, italics.
For example, if a subtitle in a master track is flagged as raised, all subtitles (inside the same time span) in all vassal tracks will also be raised.

 

In the subtitler, use menu Track / Modify / Edit mastery to make a track master, or restore it.
