The Container secondary event allows to define the point on which the transmission of a certain block of events starts (opening container) and subsequently ends (closing container), when inserting a container it is enough to define the following fields:
Container
Active: Tick off this parameter to enable the secondary event, leave it unchecked to disable it.
Name: Give it a brief descriptive name.
Icon: Make double-click on the default icon to change it with a more suitable one.
Opening / Closing container: Define if the event will indicate either the start or the end of the 'container'.
Note: All events scheduled between an opening and a closing container event will use the same secondary events specified on the opening container (e.g. 'secondary events | subtitles', 'properties | STMan', etc). If a closing container is missing after an opening container, the opening container will affect all following events until the end of the day (it will be ignored in following days).
Media Library [F7]: Open the Media Library clicking on this button on the secondary event's toolbar. It allows to load the asset related to the primary event for which the secondary event is being defined. If there are unsaved changes, before opening Media Library a message will be prompted, asking to save or not the modifications to the secondary event.
