Extracting Meta Data from video files

[mfryd]

Is there any documentation, or known working extraction tools, that can get Photo Mechanic inserted meta data out of video files?

We use Photo Mechanic to add meta data to our files (captions, keywords, descriptions, etc.).   The files are then loaded into our custom web based content management system.   The web based system can easily pull out the standard IPTC fields from JPEG files, but we have been unable to extract any Photo Mechanic inserted data from video files.

We are using the the extract tool from Lib Extract (http://www.gnu.org/software/libextractor/), which works with iTunes purchased video, but it doesn't see Meta Data added by Photo Mechanic.

We would like for our system to support Photo Mechanic for adding Meta Data to videos.  Is there any documentation on how Photo Mechanic stores meta data in video files?

Are there any command line tools for extracting this data?

Thanks

PM does not insert metadata into movie files.  If you're on a Mac, then metadata will be written to the resource fork of the movie.  The resource fork wouldn't be available once the file is uploaded (most servers don't support resource forks.)

I do not know if there are tools that will look at resource forks for metadata, but the format of the metadata will be standard IPTC and/or XMP.
