Edit, Split, Merge And Preview Subtitles In VLC Player With Gaupol

Gaupol is a free subtitle editing tool for Windows and Linux which allows editing text-based subtitle files. It provides means of creating subtitles, editing texts and timing subtitles to match video duration. The user interface is designed to provide batch processing capability with tab support. Gaupol is meant to help users edit every single line with the convenience for translating existing subtitles. The edited subs can also be previewed in a user selected media player. It auto detected the path of my installed VLC Player, after which I was able to preview any edited line of the subtitle by simply using the Play button. You can also specify other media players which may have VLC like capabilities such as MPlayer.

Gaupol supports all commonly used subtitle formats which include the following:

  • SubRip (SRT)
  • SubViewer 2.0
  • MicroDVD
  • MPL2
  • MPsub
  • TMPlayer

Gaupol also partially supports some other formats which include Sub Station Alpha and Advanced Sub Station Alpha. Just add a subtitle file from Open main files button to load it for editing. As you can see from the below screenshot, you can edit subtitles lines and set their duration by simply double clicking on an area of the loaded subtitle file.

Other features of Gaupol include unlimited undo and redo facility, speech recognition to generate subtitles from video, the option to use CTRL+F to find and replace subtitles, text formatting options, spell checking, correction of common errors, removal of hearing impaired text, etc. To select a media player (if you do not wish to use VLC), go to Edit drop down menu, select Preferences and change the media player from the Preview tab.
