How to Extract Subtitle from MKV Files with VLC Media Player

First of all, after we researched and tried several different methods mentioned on the internet, it turned out that VLC media player cannot extract the subtitles contained in the MKV files.

A few moments later, luckily you will see the subtitle results that VLC finds on the internet for you.

FAQs about Extracting Subtitles from MKV

1. What kind or format can MKV subtitles (or Matroska subtitles) be?

MKV subtitles can be in various formats, such as:

  • SRT: This is the simplest and most common subtitle format. It consists of plain text files with time codes for each line of dialogue. It has good compatibility and can be played with any device and platform.
  • ASS: This is a more advanced subtitle format that supports complex formatting and animation. It can display different fonts, colors, sizes, positions, and effects for the subtitles. It is mainly used for anime and fan-made subtitles.
  • VobSub: This is a subtitle format that consists of two files: an IDX file that contains the index of subtitle time and position locations, and a SUB file that contains the actual graphical subtitles. It is often used for DVD subtitles.
  • PGS: This is a subtitle format that uses bitmap images to display the subtitles. It is often used for Blu-ray subtitles. It can support multiple languages, fonts, and styles.
  • VTT: It is short for Web Video Text Tracks Format. It is a subtitle format that is mainly used for adding timed text tracks, captions, and subtitles to HTML5 video and audio elements. It is similar to the SRT format, but it has some additional features, such as:
    • It can support metadata, such as title, language, kind, etc.
    • It can support styling, such as font, color, size, position, etc.
    • It can support cues, such as voice, sound, chapter, etc.
  • The VTT format is widely supported by modern browsers and web platforms, such as YouTube, Vimeo, Netflix, etc. It is also compatible with some media players, such as VLC, Media Player Classic, etc. However, some older devices or platforms may not support the VTT format, so you may need to convert it to SRT or other formats if you encounter compatibility issues.

There are also other subtitle formats that can be used in MKV files, such as STL, EBU STL, SAMI, XML, SCC, etc. However, they are less common and may not be supported by some players or devices.

2. What is the difference between hardcode MKV subtitles and softcode MKV subtitles?

The difference between hardcode MKV subtitles and softcode MKV subtitles is that hardcode subtitles are burned into the video stream, while softcode subtitles are embedded as a separate track in the MKV file. Hardcode subtitles cannot be turned off or changed by the player, while softcode subtitles can be toggled on or off, and adjusted for appearance and timing. Hardcode subtitles may affect the video quality and require re-encoding, while softcode subtitles preserve the original video and are more flexible. However, both of them can be extracted from the MKV files.
