The Metadata panel shows both clip-instance metadata and
XMP file metadata for a selected asset. Fields under the Clip heading
show clip-instance metadata: information about a clip selected in
the Project panel, or in a sequence. Clip instance metadata is stored
in the Premiere Pro project file, not in the file to which the clip
points. Only Premiere Pro reads clip instance metadata not, other applications.
However, in Premiere Pro you can link some clip metadata fields with
XMP metadata fields. This option allows applications outside Premiere
Pro to access the clip-based metadata by way of the XMP fields.
If you never use subclips and never import multiple instances
of master clips, then each clip in your project is unique. You can
use XMP File properties exclusively, so all your metadata is recorded
into the source file, visible to other applications. Alternatively,
you can use the traditional Clip properties, but turn linking on
for all of them. Premiere Pro automatically copies the clip data
into the matching XMP properties, from that point on.
Fields under the File and the Speech Transcript headings show
XMP metadata. Using Speech Search, you can transcribe words spoken
in a clip to text. Then search the text to find where a specific
word is spoken in the clip. For more information about using Speech
Search, see Convert speech to text metadata.
For more information about XMP metadata, see the overview on
the Adobe website.
