I was talking about the Metadata documentation referenced by Jim:

http://ffmpeg.org/ffmpeg-all.html#Metadata-1

"

By using the ffmetadata muxer and demuxer it is possible to extract 
metadata from an input file to an ffmetadata file, and then transcode 
the file into an output file with the edited ffmetadata file.

Extracting an ffmetadata file with ffmpeg goes as follows:

ffmpeg -i INPUT -f ffmetadata FFMETADATAFILE

Reinserting edited metadata information from the FFMETADATAFILE file can 
be done as:

ffmpeg -i INPUT -i FFMETADATAFILE -map_metadata 1 -codec copy OUTPUT
