This tutorial will show you step by step how to merge SRT or SUB and IDX subtitle files with an MKV video file permanently.

MP4Tools is a collection of cross-platform free tools to manipulate MP4 files. It contains following applications: MP4Joiner is a free application that allows join multiple MP4 files into one without reencoding and without quality loss. MP4Splitter is a free application that allows split a MP4 file in multiple files without reencoding. Mkvmerge: MP4 reader: sped up parsing MP4 DASH files with a lot of segments (trun atoms) quite a bit. Part of the fix of #2900. The PCRE2 regular expression library is now used instead of std::regex for big performance improvements in all places where regular expressions are used for parsing big chunks of text, e.g. In the subtitle parsers.

You can also merge multiple subtitle files with an MKV video file.

How to merge subtitles with an MKV video using MKVToolNix

MKVToolNix is a set of free tools to create, split, edit, mux, demux, merge, extract, and inspect MKV video files.

It's available for Microsoft Windows, Linux, and macOS.

You can install this tool on your computer, or you can use the portable version.

You can download MKVToolNix here (official website).

The steps below will show you how to permanently embed (hardcode) the subtitles into an MKV video file.

1. Make sure that the subtitle file is in the same folder as the MKV video file.

2. Make sure that the subtitle file has the same filename as the MKV video file.

Example:

• Movie.mkv
• Movie.srt
• Movie.sub
• Movie.idx

3. Open MKVToolNix.

4. Click on the + Add source files button located at the bottom.

A “Add media files” window will appear.

5. Within this window, you go to the location on your computer where the MKV video and subtitle file(s) are.

6. Select the MKV video file and subtitle file(s) (.srt, .sub or .idx).

7. Click on the Open button.

8. In the Destination file section (located at the bottom), you can see and change the location on your computer where MKVToolNix will save the new MKV video file.

You can change the location by clicking on the (folder) button located next to the “Destination file” field.

9. When you're ready, you click on the Start multiplexing button at the bottom.

MKVToolNix will now merge the SRT or SUB and IDX subtitles with the MKV video file.

Hello dear people,

I sincerely hope you’re all healthy or at least on the way there. I’m fine, and having some more time on my hands I was able to get more done wrt. MKVToolNix. So this release is a bit bigger than the previous ones.

Nothing’s changed for package managers.

You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are stil being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

New features and enhancements

Mkvmerge Gui

• mkvmerge: mkvmerge has never supported appending & splitting FLAC audio
  tracks. mkvmerge will now emit error messages when the user attempts either
  instead of continuing and creating invalid FLAC tracks.
• MKVToolNix GUI: added an option in the preferences to turn on eliding text
  on tab headers. If enabled, tab names will be shortened so that all tab
  headers fit into the window’s width. Implements #2768.
• MKVToolNix GUI: added an option in the preferences to disable all tooltips.
• MKVToolNix GUI: Windows: debug output sent via Qt’s to Windows’ debugging
  facility will use a more verbose message format including the application
  name, making it easier to filter for in SysInternal’s 'Debug View' utility.
• MKVToolNix GUI: multiplexer: if the file identification fails due to a JSON
  parser error, the output generated by mkvmerge will be output via Qt’s
  debugging facility (viewable with SysInternal’s 'Debug View' utility on
  Windows; on other systems it’s output on STDERR) allowing insight into
  what’s gone wrong.
• MKVToolNix GUI: multiplexer: if an error occurs during file identification,
  the name of the processed file will be mentioned in the error message.
• MKVToolNix GUI: multiplexer: if an error occurs during identification of
  multiple files, the GUI will ask the user whether to continue or abort the
  identification process. Implements #2778.
• MKVToolNix GUI: job queue: added an option in the preferences for removing
  completed jobs when exiting the program depending on their status.
  Implements #2769.

Bug fixes

• mkvmerge: H.265/HEVC packetizer: fixed changing the NALU size length, it was
  using the wrong offset into the hevcC structure.
• mkvmerge: MP4 reader: fixed calculating the duration of video tracks that
  only contain a single frame. Fixes #2747.
• mkvmerge: MP4 reader: if there’s no frame offset table (ctts atom) present
  for H.265/HEVC video tracks, mkvmerge will determine the timestamp order
  itself instead of relying on the timestamps in the MP4 being in the
  presentation order required by Matroska. Fixes #2777.
• mkvpropedit: Windows: mkvpropedit wasn’t caching when reading the file to
  modify, slowing down operations such as adding track statistics tags
  considerably. Fixes #2761.
• MKVToolNix GUI: multiplexer: when using the title as part of the destination
  file name (both automatically as well as using the 'copy title to
  destination file name' function) all characters that aren’t valid in a file
  name are replaced by hyphens.
• MKVToolNix GUI: multiplexer: the 'copy title to destination file name'
  function was broken when the 'make file name unique' option in the
  preferences was disabled. In that case the file base name was removed
  regardless of what the title was set to at the time.
• MKVToolNix GUI: multiplexer: when using the 'show command line' menu option
  on Windows the path to the mkvmerge executable was shown with forward
  slashes instead of backslashes. This is a purely cosmetic fix as Windows
  supports both forward and backward slashes.
• MKVToolNix GUI: multiplexer: when adding Blu-ray playlists the GUI used to
  only look for the English version of the disc library information (title &
  cover images). Now the GUI will present all disc library entries in the
  'select playlist to add' dialog & let the user chose which one to use (if
  any). Fixes #2765.
• MKVToolNix GUI: multiplexer, info tool: fixed the 'warn before overwriting'
  check wrt. jobs creating the same file. Fixes #2758.
