  • "tracks": Specifies the mode or action to be performed by mkvextract, which is track extraction.
  • "${filename-mkv}": This is a variable representing the name of the MKV file from which the tracks will be extracted. It should be replaced with the actual file name.
  • "${1}:${path-to-output-webm}": These are two variables separated by ":". "${1}" refers to the number of the track within the MKV file that needs to be extracted. It should be replaced with the actual track number. "${path-to-output-webm}" represents the path or directory where the extracted track(s) will be saved in the WebM format.
