# Why use this command?
WebM and MKV are related (both use Matroska-based structures). This conversion is useful for adding more tracks or metadata to your WebM content.
# Parameter Explanation
The streams from the WebM input are placed into the MKV container. Since they share ancestry, this is a very 'clean' conversion for FFmpeg.
