Jubler is a tool to edit text-based subtitles. It can be used as an authoring software for new subtitles or as a tool to convert, transform, correct and refine existing subtitles. The most popular subtitle formats can be used. Preview of the subtitles in realtime or in design time, spell checking, translation mode and styles editing are some of the main features.
It is open source under a liberal (GNU) public license. It is written in Java 5.0 (a.k.a. Java 1.5.0) in order to be really multi-platform. It has been tested under Linux, Windows XP and Mac OS X.
