Add metadata

  • Article

Metadata is a valuable component of web media. Accurate and complete metadata helps you and other users successfully search and categorize media. In Microsoft Expression Encoder, you can enter metadata in many categories, and also read the existing metadata in any media that you import. By default, the Metadata category (in the Metadata panel) displays the Title, Author, Copyright, Rating, Credits, and Description boxes, but you can expand the list to show other metadata that you can enter. You can also add any number of custom metadata fields, or decide which ones will be displayed by default.

If you are working in a Transcoding Project or a Silverlight Project, when you save your job, Expression Encoder embeds the metadata in the file header. If you are working in a Live Broadcasting Project, the metadata that you add is present in the broadcast stream when you are performing a live broadcast, and is also stored with the file if you decide to archive it.

If you save the job, in the resulting job file, Expression Encoder stores the metadata attributes in name-value pairs as a child of the MediaFile element (or, if you archive a Live Broadcasting file, as a child of the LiveJob element), as in the following example.

<Markers>
<Metadata>
 <Item
  Name="Title"
  Value="The Bear" />
 <Item
  Name="Author"
  Value="EVM" />
 <Item
  Name="Copyright"
  Value="2010" />
</Metadata></Markers>

For more information, see Save job files.

To view and add metadata

  1. If you are working in a Silverlight Project or a Transcoding Project, in the Media Content panel, select the videos to which you want to add metadata.

    Note

    If you are working in a Live Broadcasting Project, the metadata will apply only to your current broadcast because you cannot broadcast more than one program at a time. Therefore, you cannot select a video to which to add the metadata.

  2. If you can't see the Metadata category, on the Window menu, click Metadata to open the Metadata panel. If Metadata is already selected, but you still can't see the Metadata category, click the Metadata tab.

  3. Click Show/Hide advanced propertiesCc294542.2f8a79a9-68d2-4878-8b75-c76ceb921b3b(en-us,Expression.40).png to expand or collapse the list of metadata. The default list of Title, Author, Copyright, Rating, Credits, and Description boxes is always visible, unless you collapse the category.

  4. Click inside any box to type text.

To create and manage metadata labels (attributes)

  1. On the Tools menu, click Options.

  2. Click Metadata attributes.

  3. Do one of the following:

    • To create a custom attribute, click Add and type the name of the attribute.

    • To change the name of an attribute, select an attribute from the list and click Edit. Type a new attribute name.

    • To delete an attribute, select one from the list and click Remove.

  4. Click OK.
