Working with metadata in MOV files Leave feedback
The GroupDocs.Metadata API supports extracting QuickTime atoms from a MOV video. The atom is the basic data unit in any QuickTime file. Please find more information on QuickTime atoms in the official specification: https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/QTFFPreface/qtffPreface.html
The following are the steps to extract QuickTime atoms from a MOV video.
- Load a MOV video
- Get the root metadata package
- Extract the native metadata package using the MovRootPackage.getMovPackage method
- Read the QuickTime atoms

try (Metadata metadata = new Metadata(Constants.InputMov)) {
MovRootPackage root = metadata.getRootPackageGeneric();
for (MovAtom atom : root.getMovPackage().getAtoms()) {
System.out.println(atom.getType());
System.out.println(atom.getOffset());
System.out.println(atom.getSize());
// ...
}
}
GroupDocs.Metadata for Java allows managing XMP metadata in MOV files. For more details please refer to the following guide: Working with XMP Metadata.
The code sample below shows how to update XMP properties in a MOV video. If the file has no XMP package or the required schemes yet, they are created first.
advanced_usage.managing_metadata_for_specific_formats.
try (Metadata metadata = new Metadata(Constants.InputMov)) {
IXmp root = (IXmp) metadata.getRootPackage();
if (root.getXmpPackage() == null) {
root.setXmpPackage(new XmpPacketWrapper());
}
if (root.getXmpPackage().getSchemes().getDublinCore() == null) {
root.getXmpPackage().getSchemes().setDublinCore(new XmpDublinCorePackage());
}
root.getXmpPackage().getSchemes().getDublinCore().setFormat("video/quicktime");
root.getXmpPackage().getSchemes().getDublinCore().setRights("Copyright (C) 2011-2026 GroupDocs. All Rights Reserved.");
root.getXmpPackage().getSchemes().getDublinCore().setSubject("test");
if (root.getXmpPackage().getSchemes().getXmpBasic() == null) {
root.getXmpPackage().getSchemes().setXmpBasic(new XmpBasicPackage());
}
root.getXmpPackage().getSchemes().getXmpBasic().setCreateDate(new Date());
root.getXmpPackage().getSchemes().getXmpBasic().setLabel("GroupDocs");
root.getXmpPackage().getSchemes().getXmpBasic().setRating(5);
// ...
metadata.save(Constants.OutputMov);
}
