## Matroska Tags

The following tags are extracted from Matroska multimedia container files. This container format is used by file types such as MKA, MKV, MKS and WEBM. For speed, by default ExifTool extracts tags only up to the first Cluster unless a Seek element specifies the position of a Tags element after this. However, the Verbose (-v) and Unknown = 2 (-U) options force processing of Cluster data, and the ExtractEmbedded (-ee) option skips over Clusters to read subsequent tags. See http://www.matroska.org/technical/specs/index.html for the official Matroska specification.
