Subtitle Extractor – How to Extract Subtitles from MKV, MP4, or Others?
MKV is a free and open-source container format, capable of holding multiple video, audio, and subtitle tracks in one file. It is well known for storing multimedia contents like movies or TV shows. If you have collected some MKV downloads or get some MKV rips from Blu-ray disc, chances are you may want to extract subtitles from MKV video.
For example, the original MKV file might be low in quality, so you just want to pull out subtitles from MKV and add them to a high-resolution video that doesn’t come with its own subtitles, so that you can get a better visual experience. It is also a good way to watch media file in the language without subtitles if you want to master a language or practice listening. Or you’d like to access to the classic lines and dialogues in a movie. Whatever the reason is, a subtitle extractor that is able to extract subtitles from MKV, MP4, MOV, or other media files is deemed as indispensable.
Note: Soft subtitles are independent and can be extracted, disabled, or removed easily. But hard subtitles are part of the video, so you cannot extract the hardcoded subtitles from any video including MKV. You can only crop the video to get rid of the hard subtitles with software like HD Video Converter Deluxe. With it, not only can you disable subtitles, crop video to remove hardcoded subs, but also hardcode the extracted subtitles into the original MKV file, trim and merge the video clip, convert video to mainstream format at ease.

FAQ about Subtitle Extraction
1. Can VLC Extract Subtitles?
No. VLC is a world-known media player with many features like playing media files, convert videos, record screen and more. However, you cannot extract subtitles with VLC media player. Instead, you can turn off subtitles and choose the subtitle tracks as you like. You have to rely on MKVToolNix to extract subtitles instead.
2. Soft Subtitle vs Hard Subtitle, What's the Difference?
Soft Subtitle, also known as softsub, means the video and the subtitles are wrapped in one file, which you can play them together with media player like VLC, 5KPlayer or Potplayer. This means it easy to enable, turn off, alter, remove, or extract subtitles from the video. Compared with softsub, hard subtitle, known as hardsub, is built into the video permanently. It is part of the video so you can stream and watch it everywhere with the movie, but cannot disable, remove, or separate the subtitles from video.
