AviSub is an application which can prove to be really helpful for users that need to add subtitles to AVI files and use them later on different devices. AVI is a trustful format that plays back on most players and it is usually accompanied by soft subtitles which can be manually added by users. However, this is not always the solution and a DVD player, for example, will not be able to play back the subtitle along with the video file.

This is why AviSub is useful, as it manages to integrate AVI movies with subtitles in different formats. Users are able to mux subtitles with the video and up to three different subtitle tracks can be added at once. This is useful when more than one subtitle has to be added onto the movie. Each subtitle can have its own parameters set up, such as the starting time and individual line times can also be edited.

AviSub manages to add subtitles onto the movie and then it converts it into a DivX format, useful for DVD players. This way, people can enjoy subtitled movies on their players without having to work with DVD movie files directly. The whole process takes only minutes to complete so that users can quickly benefit from their output files.
