+
+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 @file{ffmpeg} goes as follows:
+ at example
+ffmpeg -i INPUT -f ffmetadata FFMETADATAFILE
+ at end example
+
+Reinserting edited metadata information from the FFMETADATAFILE file can
+be done as:
+ at example
+ffmpeg -i INPUT -i FFMETADATAFILE -map_metadata 1 -codec copy OUTPUT
+ at end example
+
 @c man end METADATA
