About:
MKVToolNix is a comprehensive set of tools to create, alter, and inspect Matroska (MKV) media files. It allows users to multiplex video, audio, and subtitle tracks into a single container, split files, or extract tracks without re-encoding. Its core utility lies in its powerful command-line utility 'mkvmerge', which provides precise control over metadata and container structure.
Key Features:
  • mkvmerge for multiplexing and combining media streams
  • mkvextract for extracting tracks from MKV containers
  • mkvinfo for analyzing file structure and codec details
  • mkvpropedit for editing metadata without remuxing
Use Cases:
  • Combining high-quality video and audio tracks into a single MKV file
  • Adding or removing subtitle tracks from existing video files
  • Fixing or updating metadata tags on media files
Alternatives:
  • FFmpeg – FFmpeg is a broader multimedia framework, while MKVToolNix specializes specifically in the Matroska container format with more granular control.
