o Some MXF files (Digital Cinema Intermediate) may contain encrypted data tracks
that you will be able to extract only if you provide the right key. To set the key,
right click on the protected track from a source package and select
SetCipherKey. This will open a dialog box, where will be reminded the public key
protecting this track and where you will be asked to set the corresponding private
key.
Note
If you have selected a mono AES3 audio track (as found in SONY XDCam
DV or Panasonic P2 files), you are given the option to extract the audio in
WAV format instead of AES format. To do so, you simply need to activate
Options > Extract AES to WAVE before performing the extraction.
2.2.4 Metadata Tracks
This view will be available only if the MXF file contains descriptive metadata tracks. It
displays the metadata tracks of the package you selected in the previous view. MXF
organizes descriptive metadata in tracks, each track contains one or several metadata
segments used to annotate a given time span. Then, each metadata segment contains a
descriptive metadata tree following a standardized descriptive metadata scheme. The
most commonly used scheme in the MXF world is the Descriptive Metadata Scheme 1
(ST380 - DMS-1) which gives the choice between 3 different metadata trees (also called
frameworks) to append to metadata segments. Finally, MXF allows three different types
of descriptive metadata tracks, each of them allowing different assembly of metadata
segments:

Static tracks contain metadata segments referring to the entirety of the package.
These tracks do not have origin or duration.

Timeline tracks are used to annotate continuously the tracks of the package. They
are built as a concatenation of metadata segments.

Event tracks are used to annotate sporadically the tracks of the package. Parts of the
track may have no metadata segments and metadata segments may overlap.
If you right-click on a metadata segment you will be given the option to extract its
metadata tree in an XML file. If you select this option a file dialog will open to let you
specify the location of the XML file to be created.
