Import Clip Notes comments as composition markers
1 Select the composition into which to import the Clip Notes comments.
The selected composition should be the composition from which you rendered the movie that was sent for comments.
If you have modified the composition since you rendered the movie for comments, the imported comments may not
be associated with the appropriate parts of the composition.

XMP metadata
About XMP metadata
Metadata is—in the simplest sense—data about data. In practical terms, metadata is a set of standardized information
about a file, such as author name, resolution, color space, copyright, and keywords applied to the file. For example,
most cameras attach some basic information to video files, such as date, duration, and file type. Other metadata can
be entered as shot-list information in OnLocation or at the capture stage in Adobe Premiere Pro. You can add
additional metadata with properties such as location, author name, and copyright. Because you can share, view, and
use this metadata across Adobe Creative Suite applications, you can use this information to streamline your workflow
and organize your files.
The Extensible Metadata Platform (XMP) is the metadata standard used by Adobe applications. Metadata that is stored
in other formats—such as Exif, IPTC (IIM), GPS, and TIFF—is synchronized and described with XMP so that it can
be more easily viewed and managed. For example, adjustments made to images with Adobe Camera Raw are stored as
XMP metadata. The XMP standard is based on XML.
In most cases, XMP metadata for a file is stored in the file itself. If it isn’t possible to write the information directly into
the file, XMP metadata is stored in a separate file called a sidecar file, with the filename extension .xmp. For
information on which file formats After Effects can write XMP metadata directly into, see “
Importing files with XMP
metadata into After Effects ” on page 627.
In most cases, XMP metadata remains with the file even when the file is converted to a different format—for example,
from PSD to JPG. XMP metadata is also retained when files are placed in a document or project in an Adobe Creative
Suite application.
A metadata schema is a collection of properties specific to a given workflow. The Dynamic Media schema, for example,
includes properties such as Scene and Shot Location that are tailored for digital video projects. Exif schemas, by
contrast, include properties tailored to digital photography, such as Exposure Time and Aperture Value. More general
properties, such as Date and Title, appear in the Dublin Core schema. To see a tool tip with information about a
specific schema or property, place the pointer over it in the Metadata panel. You can create your own schemas using
commands in the Metadata panel, and you can import schemas and share them with others as XML files.
