Working with metadata in MOV Files

Reading MOV format-specific properties

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.

  1. Load a MOV video
  2. Get the root metadata package
  3. Extract  the native metadata package using MovRootPackage.MovPackage
  4. Read the QuickTime atoms

AdvancedUsage.ManagingMetadataForSpecificFormats.Video.Mov.MovReadQuickTimeAtoms

using (Metadata metadata = new Metadata(Constants.InputMov))
{
	var root = metadata.GetRootPackage<MovRootPackage>();
	foreach (var atom in root.MovPackage.Atoms)
	{
		Console.WriteLine(atom.Type);
		Console.WriteLine(atom.Offset);
		Console.WriteLine(atom.Size);

		// ...
	}
}
