Encoding and exporting
Last updated 12/15/2014
If you choose None, then no XMP metadata from the source will be embedded in the file, and none of the other controls
for XMP metadata export are available. Basic XMP metadata about the exported file—such as export settings and start
timecode—is always exported, even when None is chosen.
Note: The Embed In Output File options are disabled for files of kinds for which XMP metadata can’t be embedded.
Preserving XMP metadata from sources
Many source assets contain XMP metadata. You can choose which XMP metadata from source assets should be
preserved in the encoded output files by using a preservation rule.
For single-source clips, preserving XMP metadata ensures that the production metadata from the original source flows
through to the re-encoded output file. For sequences and compositions, including source metadata preserves the
metadata from each of the items used to make up that sequence or composition. Excluding existing source metadata is
often referred to as thinning. You may want to exclude source metadata for security purposes or privacy concerns, or to
reduce the size of the output file as much as possible.
A preservation rule acts as a filter to specify which XMP metadata from a source item is passed through to an encoded
output file. The preset preservation rules are Preserve All and Exclude All. Preserve All is the default.
To create your own preservation rule, click New next to the Preservation Rules menu. You can enable individual fields
or categories by selecting them in the Preservation Rules Editor dialog box. To find specific fields, use the search field
near the top of the Preservation Rules Editor dialog box. Be sure to give your preservation rule a descriptive name.
You can edit an existing custom preservation rule by choosing it from the Preservation Rules menu and clicking Edit.
Two kinds of source XMP metadata are handled separately from the source XMP metadata controlled by the
preservation rules: sequence markers and the XMP metadata that is created by the speech analysis features in Adobe
Premiere Pro. To include the speech XMP metadata and sequence markers, select Export Master Speech Track And
Sequence Markers.
Note: Speech-to-text has been removed in the latest release of Adobe Media Encoder. However, any speech to text metadata
that has already been generated can be used in exactly the same way as it was before.
Adding XMP metadata
An export template specifies what XMP metadata will be written to the output file. For example, you can create an
export template that includes various XMP metadata from the source files as well as adding your contact information
and rights-management information to each output file.
The export template acts as a filter; any fields that are not explicitly enabled by the current template will be filtered out.
The only exceptions are internal properties that are automatically populated with data by the creator application, which
are always included and are not editable.
To create your own export template, click New next to the Export Template menu. You can enable individual fields or
categories by selecting them in the Export Template Editor dialog box. To find specific fields, use the search field near
the top of the Export Template Editor dialog box. Be sure to give your export template a descriptive name.
You can edit an existing custom export template by choosing it from the Export Template menu and clicking Edit.
After you have applied an export template, you can also manually enter values to add specific XMP metadata to the
current encoding queue items.
