    GROUPS => { 2 => 'Video' },
    NOTES => q{
        The QuickTime format is used for many different types of audio, video and
        image files (most commonly, MOV and MP4 videos).  Exiftool extracts standard
        meta information a variety of audio, video and image parameters, as well as
        proprietary information written by many camera models.  Tags with a question
        mark after their name are not extracted unless the Unknown option is set.

        ExifTool has the ability to write/create XMP, and edit some date/time tags
        in QuickTime-format files.

        According to the specification, many QuickTime date/time tags should be
        stored as UTC.  Unfortunately, digital cameras often store local time values
        instead (presumably because they don't know the time zone).  For this
        reason, by default ExifTool does not assume a time zone for these values.
        However, if the QuickTimeUTC option is set via the API or the ExifTool
        configuration file, then ExifTool will assume these values are properly
        stored as UTC, and will convert them to local time when extracting.

        See
        L<http://developer.apple.com/mac/library/documentation/QuickTime/QTFF/QTFFChap1/qtff1.html>
        for the official specification.
