The low-level identifier column lists the atom name that the format uses to encode the data on disc, which is not interesting to most readers. The following table shows the metadata keys that FFmpeg honors when muxing a QuickTime file. This page documents which keys FFmpeg will encode into which formats. Many formats only support a handful of metadata keys. Whether the metadata key/value pairs are actually encoded into the output file is dependent upon the file format being muxed. The option is -metadata and is used as such:įfmpeg -i inputfile -metadata title="Movie Title" -metadata year="2010" outputfile
FFmpeg has a free-form command line option that allows the user to specify key/value pairs for encoding metadata.
