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 licence. It is written in Java 5.0 in

order to be really multi-platform. It is available for Linux, Windows XP/Vista and Mac OS X.

Avidemux is a free video editor designed for simple cutting, filtering and encoding tasks. It supports many file

types, including AVI, DVD compatible MPEG files, MP4 and ASF, using a variety of codecs. Tasks can be

automated using projects, job queue and powerful scripting capabilities. Avidemux is available for Linux, BSD,

Mac OS X and Microsoft Windows under the GNU GPL license. Here we will use this software to add subtitles

and encode our video.

In this guide it’s described how to create your own subtitles for a video clip using Jubler and after that how to

embed them on the clip using Avidemux.

Launch Jubler and select either File > New or the New button in the toolbar to start a new project (1).

Next click on the Enable/Disable Preview button to load the clip you want to create subtitles for. Browse to

the location you have the clip (1) and click OK . If you want you can select to use a different audio stream and

work with that (2).

A video preview window has opened (1) along with a waveform visualization of the clip's audio sound (2). You

can use the zoom in/out scroll bar to locate the exact time of the movie you want to add subtitles (3) which it

will be shown later how to do it.

But first you must set some preferences for the subtitles. Click on File -> Preferences and a new window will

appear. In the first tab if you are using Windows or Linux select UTF-8 as First Encoding (1), unless you have

some special encoding for your language. Next click on the Get FPS from video file button (2), or select your

clip's FPS from the drop down menu if you know it.

In the Save tab you can select the format you want your subtitles to be saved to. There are many supported

formats such as Advanced SubStation, SubStation Alpha, SubRip. SubViewer (1 and 2), MicroDVD, MPL2 and

Spruce DVD Maestro. Here it will be used the .srt file format (1).

In the Player tab you can select the player you want Jubler to open to test your subtitled video. It can

recognize mplayer on its own (1).

If you are not good in spelling Jubler uses ASpell speller to check what you are writing.

When you have finished with the configuration click on Accept to return to main program window.

To start creating your subtitles you must select the part of the waveform in which there is voice. To do so grab

the left and right edge of the blue part of the waveform (1). The Start and End time of the subtitles will appear
