A subtitle editor is a type of computer software that lets users create and edit subtitles. These subtitles are superimposed over, and synchronized with, video. Subtitles can literally make the difference between being immersed in a movie or only watching the screen, trying to keep up with developments. Good subtitling does not distract but actually enhances viewing pleasure, and even native speakers can find subtitles useful, not only where the individual is hearing-impaired.
The software featured in this article also offer an easy way to perform a number of different editing jobs, besides adding and removing subtitles. They each boast a good feature set, and are all released under an open source license.
