Aegisub is a subtitle editing application. It is the main tool used for fansubbing, the practice of creating or translating unofficial subtitles for visual media by fans. [3] It is the successor of the original SubStation Alpha and Sabbu.
Aegisub's design emphasizes timing, styling of subtitles, and the creation of karaoke videos. It allows for many video processing bindings to process the timing, such as FFmpeg and AviSynth. It can also be extended with the Lua and MoonScript scripting languages. [4]
The app's native subtitle format is Advanced SubStation Alpha, which supports subtitle positioning and styling. Aegisub can export subtitles to other common formats as well, such as SubRip's ".srt" format, [5] but at the cost of losing all other features except for raw text and basic timing.
In fansubbing, Aegisub is used when translating and interpreting languages, creating and adjusting timing, editing subtitles, typesetting, quality checking, karaoke lyric timing and karaoke text effects. However, different tools can be used to achieve the same effect, such as Adobe Premiere Pro for typesetting, [6] or a simple text editor like Notepad++ when providing translated text. [7]
Desktop publishing (DTP) is the creation of documents using dedicated software on a personal ("desktop") computer. It was first used almost exclusively for print publications, but now it also assists in the creation of various forms of online content. Desktop publishing software can generate page layouts and produce text and image content comparable to the simpler forms of traditional typography and printing. This technology allows individuals, businesses, and other organizations to self-publish a wide variety of content, from menus to magazines to books, without the expense of commercial printing.

A fansub is a version of a foreign film or foreign television program, typically anime or dorama which has been translated by fans and subtitled into a language usually other than that of the original.
Typesetting is the composition of text for publication, display, or distribution by means of arranging physical type in mechanical systems or glyphs in digital systems representing characters. Stored types are retrieved and ordered according to a language's orthography for visual display. Typesetting requires one or more fonts. One significant effect of typesetting was that authorship of works could be spotted more easily, making it difficult for copiers who have not gained permission.
Texinfo is a typesetting syntax used for generating documentation in both on-line and printed form with a single source file. It is implemented by a computer program released as free software of the same name, created and made available by the GNU Project from the Free Software Foundation.

Avidemux is a free and open-source software application for non-linear video editing and transcoding multimedia files. The developers intend it as "a simple tool for simple video processing tasks" and to allow users "to do elementary things in a very straightforward way". It is written in C++ and uses Qt for its graphical user interface, and FFmpeg for its multimedia functions. Starting with version 2.4, Avidemux also offers a command-line interface, and since version 2.6, the original GTK port has not been maintained and is now discontinued.
SubRip is a free software program for Microsoft Windows which extracts subtitles and their timings from various video formats to a text file. It is released under the GNU GPL. Its subtitle format's file extension is .srt
and is widely supported. Each .srt
file is a human-readable file format where the subtitles are stored sequentially along with the timing information. Most subtitles distributed on the Internet are in this format.
Subtitles are texts representing the contents of the audio in a film, television show, opera or other audiovisual media. Subtitles might provide a transcription or translation of spoken dialogue. Although naming conventions can vary, captions are subtitles that include written descriptions of other elements of the audio, like music or sound effects. Captions are thus especially helpful to people who are deaf or hard-of-hearing. Subtitles may also add information that is not present in the audio. Localizing subtitles provide cultural context to viewers. For example, a subtitle could be used to explain to an audience unfamiliar with sake that it is a type of Japanese wine. Lastly, subtitles are sometimes used for humor, as in Annie Hall, where subtitles show the characters' inner thoughts, which contradict what they were saying in the audio.
