Re: metadata fun

There are two python products that are interesting in this area:

Pymedia - (based on ffmpeg can read / transcode
etc a variety of media files including mov.)
MMPython - (a multimedia
metadata parser that can read all sorts of meta data eg. id3 and
quickitime atoms)

Both of which would be a good basis for going forward and building an
app that can not only read the existing meta data - but can write the
metadata too.  Usefully they are not targeted specifically at
Quicktime so would be a basis for a more generic system of multimedia
file metadata manipulation.

The quicktime api documentation of MOOV atoms can be found here -
(quicktime is just a container format - so the video stream has a
separate MOOV atom as does the video stream and the metadata etc)

Quicktime file format specification here:

What we need is a standalone crossplatform app that can (in the manner
of ccpublisher) alter the metadata atom and leave the rest of the
quicktime file intact.

Currently - we have to things like quicktime pro to make these
modifications - but that is really only suitable for manual use on
individual files on either windows or macs.

I am more interested in a truly system that would allow users to
upload files to a server and edit the metadata through the web or to
batch process files on the desktop.
