Markers and metadata
Last updated 12/21/2009
To see Files metadata in the Metadata panel, you must first select a file in the Project panel. You can then add or change
information in any of the metadata categories. If you select multiple files, then changes that you make will be made in
all of the selected files. Any changes made to source file metadata are immediately written to the source files.
To change which metadata categories and fields are shown in the Metadata panel, choose Project Metadata Display
Preferences or Files Metadata Display Preferences from the Metadata panel menu.
Conversion of XMP metadata to layer markers
When you create a layer based on a footage item that contains XMP metadata, the temporal metadata can be converted
to layer markers.
❖
To enable the automatic conversion of XMP metadata to layer markers, select the Create Layer Markers From
Footage XMP Metadata preference in the Media & Disk Cache preferences category.
During this conversion, After Effects shows a “Reading XMP markers from footage” status message.
These layer markers are fully editable, just as any other layer markers. (See “
Layer markers and composition markers
Changes made to the layer markers based on the source file’s XMP metadata do not affect the XMP metadata in the
source file.
To restore the layer markers for a layer to those read from the layer’s source’s XMP metadata, right-click (Windows)
or Control-click (Mac OS) any marker on the layer and choose Update Markers From Source. This command also
removes any markers that you have added to the layer. You can use this command to manually create layer markers from
XMP metadata if you did not have the Create Layer Markers From Footage XMP Metadata preference selected when you
created the layer.
For information on using expressions together with the contents of layer markers, see “
Exporting XMP metadata from After Effects
When you render and export a composition, you can write XMP metadata to the output file that includes all of the
XMP metadata from the sources for that composition. This includes all of the composition markers and layer markers
in the composition, all of the XMP metadata from the source files on which the layers in the composition are based,
comments from the Comments columns in the Timeline panel and Project panel, and the project-level XMP metadata
for the project in which the composition is contained. XMP metadata from nested compositions is recursively
processed and included in the output.
To write all of the XMP metadata to the output file, make sure that the Include Source XMP Metadata option is selected
in the output module settings for the output file. If the Include Source XMP Metadata option is deselected, the only
XMP metadata that is written to the output file is a unique ID. (See “
Output modules and output module settings
page 700.)
In addition to storing XMP metadata in After Effects project (.aep, .aepx) files and source documents used by Adobe
applications (for example, .psd), After Effects can write XMP metadata directly into the files for many container
formats, including the following:
•
FLV and F4V
•
QuickTime (.mov)
•
Video for Windows (.avi)
•
Windows Media (.wmv)
•
some MPEG formats (.mpg, .m2v, .mp4)
