OpenCube MXFTk® Front-End in Practice 19
There are four fundamental settings to keep in mind when creating a metadata segment:

Duration: this is the duration (expressed as a number of frames) of the metadata
segment along the metadata track. You should set this value if you are working on an
event or timeline track. On a static track the metadata is not related to time
annotation. Event tracks allow event of a nil (0) duration and it is perfectly valid to set
the duration to -1 if it is unknown.

TC IN (timecode in): this is the starting point of the metadata segment along the
metadata track. You should set this value if you are working on an event track. On a
static track the metadata is not related to time annotation and on a timeline track the
segments are appended one after the other so that the TC IN of the following
metadata segments corresponds to the TC OUT of the previous segment.

Framework: There are three types of predefined frameworks in the Descriptive
Metadata Scheme 1 (scene, clip and production). Each of them defines a different
metadata dictionary which suits most of the usual needs. You are given the option to
create a complete metadata tree corresponding to one of this framework by loading
an XML file. Alternatively, if you wish to build the metadata tree step by step using
OpenCube MXFTk® Front-End interface you just need to set which kind of framework
you want to work with.

Comment: This will be stored in the MXF file and should comment the nature of this
metadata segment. It will also be displayed in the views of OpenCube MXFTk®
Front-End.
2.3.4 Remove Metadata Segment
This feature is available when right-clicking on a metadata segment of a timeline or event
metadata track. It causes the permanent destruction of the segment.
2.3.5 Replace Framework
This feature is available when right-clicking on a scene, clip or production framework
node of the tree. It lets you remove the entire framework from the segment and set a new
one instead.
2.3.6 Add Metadata
This feature is available when right-clicking on a metadata set of a metadata tree. It
opens the following dialog box that lets you specify a new property that will be added as a
child to the current metadata set.
