The app organizes the dialogue by columns. The first two columns indicate the period of time that they will remain visible, the third column shows the dialogue itself, and two other columns for layering and style.
The style editor is a very complete tool that lets you change the appearance of the subtitles: color, shadowing, position on the screen, etc.
Integration between Jubler and MPlayer make it possible to see a preview of the subtitles in a clip of the film. In addition, you can also listen to the audio in the movie that corresponds to the subtitles.
Jubler also includes ASpell, a tool for correcting spelling that works with English.
