Matroska Tags

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, ExifTool extracts tags only up to the first Cluster unless the (-v) or = 2 (-U) option is used. See for the official Matroska specification.
