The 10 Best Subtitle Editor For Linux Desktop

What’s the best subtitle editor for Linux? Well, we’ll reveal it to you. A subtitle editor application lets you create and edit video subtitles on your own. Most of those movies and shows come overlaid with primed subtitles. However, some don’t contain any subtitles. For this reason, you need to use a subtitle editor or subtitle software.

The best subtitle editor tool, no doubt, will make adding files to video much more accessible and enjoyable! But, first, let’s find out what the tool actually does.

Why Use Subtitle Editor Software?

A subtitle displays narration, dialogue, or sound effects in a video file in the form of text. It transliterates the speech of a character at the bottom of a screen. However, mangled subtitles are such a buzzkill! Plus, at times, you come across subtitles of poor quality that leave you confused and baffled. At that moment, you will appreciate a subtitle editor. Subtitle editor software will come in handy in many situations.

  • Add subtitles to your video file and edit them afterward
  • Translate your favorite TV show or movie
  • Enhance and personalize your video file
  • Readjust and synchronize subtitles

Foreign-language films and soundtracks help us look at diverse cultures, society, and ultimately life through a different lens. The language barrier often deprives us of enjoying good cinema – like that time when you wanted to watch A Separation (Iran) or Parasite (South Korea).

But, not anymore! Most movies are now available in subtitles. If you’re a foreign movie buff, chances are you prefer having subtitles to listening to a dubbed version. Viewers around the world can seamlessly enjoy favorite TV shows, movies with subtitles. Even native speakers wanting to enjoy movies to the fullest sometimes need to take advantage of subtitles.

Good subtitles can enhance the viewing experience and help viewers overcome language barriers. But, sometimes, they go out of sync with the video or need complete editing. To that end, you will need subtitle edit software.

  1. I had an out-of-sync English subtitle for a Chinese martial arts film, and I was very impressed with SubSync! It does one job very well, but I will need to explore other editors as my needs expand.

    You must install a program before you can use it, so it would be helpful to have Linux installation details for each program; For example, Guapol is a FlatPak, SubSync is a Snap, and Subtitle Editor requires .Net/mono and symlink fixes.

    Thanks for writing this article. I appreciate the work you’ve put into it!
    Regards, -Jo

  2. Really inconvenient that file formats supported by each are not listed. Gnome subtitles does not support youtube’s native sbv file format.
