Can someone please explain how to embed metadata into a custom metadata field in an MP4 file with exiftool? I've searched all the docs and it seems to be related to the config file that needs to be created. Here is what I'm working with. (I know this isnt even close, as its not doing XMP fields, but I havent found a single working example with XMP fields yet. 

 %Image::ExifTool::UserDefined = (
'Image::ExifTool::Exif::Main' => {
    0xd001 => {
        Name => 'Show',
        Writable => 'string',
        WriteGroup => 'IFD0',    
},
);
1; #end

The command I'm trying to run is:

 exiftool -config exifToolConfig -show="Lightning" /reachengine/media/mezzanines/2015/02/13/13/CanyonFlight.mp4

Running this in a linux environment.

What is the properly way to set XMP metadata on custom metadata fields via ExifTool in linux on MP4 files?

The sample exiftool config file contains a number of working examples of custom XMP tags.

Basically, it is done like this:

%Image::ExifTool::UserDefined = (
    'Image::ExifTool::XMP::Main' => {
        xxx => {
            SubDirectory => {
                TagTable => 'Image::ExifTool::UserDefined::xxx',
            },
        },
    },
);
%Image::ExifTool::UserDefined::xxx = (
    GROUPS => { 0 => 'XMP', 1 => 'XMP-xxx', 2 => 'Other' },
    NAMESPACE => { 'xxx' => 'http://ns.myname.com/xxx/1.0/' },
    WRITABLE => 'string',
    MyNewXMPTag => { },
);

Then the command is

exiftool -config myconfig -mynewxmptag="some value" myfile.mp4

  • I tried this on an mp4 file and keep getting this error: Error: Writing of MP4 files is not yet supported - Am I missing something here? – JasonPerr Apr 24 '15 at 15:54
  • Does exifTool work with most MOV and MP4 files? Could there be a limitation thats causing it to just not be capable of adding metadata to my files? I added new fields to the Exif metadata via Adobe Premiere just fine. – JasonPerr Apr 24 '15 at 16:00
  • Ok, got it working in OSX. But not Linux. Guessing I need to find a way to install the most updated version on Linux. Thanks for the help. – JasonPerr Apr 24 '15 at 16:24
  • Any idea how to stop it from also generating a 2nd file named originalfilename.mov_original ? – JasonPerr Apr 24 '15 at 16:33
  • Use the `-overwrite_original` option. – lantrix Dec 30 '18 at 12:24
