Overview

Aegisub is a free, cross-platform open-source tool for creating and modifying subtitles. It makes it quick and easy to time subtitles to audio and features many powerful tools for styling them, including a built-in real-time video preview.

Aegisub subtitle editor was originally created as a tool to make typesetting, particularly in anime fansubs, a less painful experience. At the time of the start of the project, many other programs that supported the Advanced Substation Alpha format lacked (and in many cases, still lack; development on several competing programs have since been dropped for various reasons completely unrelated to Aegisub) many vital functions, or were too buggy and/or unreliable to be really useful.

Since then, Aegisub has grown into a fully-fledged, highly customizable subtitle editor. It features a lot of convenient tools to help you with timing, typesetting, editing, and translating subtitles, as well as a powerful scripting environment called Automation (originally mostly intended for creating karaoke effects, Automation can now be used much else, including creating macros and various other convenient tools).

Features and Highlights
  • Unicode in UTF-7, UTF-8, UTF-16LE and UTF-16BE encodings
  • Importing non-Unicode subtitles from over 30 different character encodings, including Shift_JIS, allowing you to resume work on any subtitles regardless of your system locale settings
  • Loading advanced Substation Alpha (.ass), Substation Alpha (.ssa), Subrip (.srt) and Plain-Text (.txt) (with actor data) subtitle formats
  • Full tag conversion from SRT to ASS
  • Multiple Undo levels
  • Powerful Automation module using the Lua scripting language to create advanced karaoke effects (including per-syllable effects, similar to AssCalc) - or any other kind of subtitles manipulation
  • Syntax highlighting
  • Fonts collector to collect all fonts used in a script into a folder
  • Opening of videos via Avisynth for a true preview of subtitles using VSFilter, in any format supported by DirectShow
  • Aspect ratio overriding for anamorphic videos
