Watching TV shows or movies can sometimes be hard for non-native English speakers. Unless the video has subtitles, it's easy to miss certain words and expressions.
With Aegisub you can create your own subtitle files or edit those you find on the web in order to adapt them to the video you want to watch and make sure you don't miss a single word.
Aegisub includes all the tools you need to create a complete subtitles file in any of the most popular subtitles formats. The program's interface features a built-in player with which you can have the video always at sight and therefore work on subtitles more comfortably. Subtitles can be inserted according to time or frame number, have rich-format elements and also show special effects – such as animated colors, perfect for karaoke.
Aegisub will probably please all subtitle specialists, but may be a bit confusing for newcomers. Luckily, it includes an extensive documentation that explains all program's functions in detail and even includes some tutorials.
