Aegisub

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. 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.

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, 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, or a simple text editor like Notepad when providing translated text.
