Bulk MKV Muxer

This a time saving Windows application written in C# that allows for batch muxing of multiple MKVs.

Typically, this application would be used following the creation of a set of MKVs from MakeMKV. A user would select the appropriate tracks to extract, and keep all streams within the tracks selected. Bulk MKV Muxer would then be used to scan the resulting MKVs to see how many captions each subtitle stream had, determine if any forced captions are present and to select the most appropriate video, audio and subtitle streams to keep in the MKV.

Additionally, this application can be used to bulk change stream basic settings; an external file can be added as a new stream to many MKVs, or default streams changed.

Prerequisites - Important

  • MKVToolNix must be installed, and the paths to relevant components must be specified in the MKV Bulk Muxer options menu.
  • Java is required for BDSup2Sub. A version of BDSup2Sub is embedded in the application, so you don't need to download it separately.

Features

  • Subtitles are automatically extracted and scanned for forced captions.
  • Video, audio and subtitle streams can be easily muxed out.
  • External video, audio or subtitle files can be easily muxed in. The file must be compatible with MKV Merge (see below).
  • Software logic suggests the most suitable streams to keep; a DTS audio stream would be chosen over Dolby Digital, and most subtitle streams would be muxed out. The only subtitle streams that would be kept in the MKVs would be English language streams that only contain a few captions. If forced captions are found in any of the English language streams, these are added as a separate stream. This suggestion is easily overridden.
  • A default stream can be specified when an MKV has multiple video, audio or subtitle streams.
  • Using BDSup2Sub, subtitle stream captions can be viewed.
  • Drag and drop functionality for files and directories.
  • Writes all output to a log file.

CLI Implementations

  • Implements the mkvinfo CLI to read and display info for the component video, audio and subtitle streams of an MKV.
  • Implements the mkvextract CLI to extract all English subtitles from an MKV.
  • Implements an embedded version of BDSup2Sub to determine the number of subtitle captions for all English subtitles, and to extract all forced captions.
  • Implements the mkvmerge CLI for bulk muxing.
