AegiSub is an advanced subtitle editor writed in wxWidgets.Aegisub was originally created as a typesetting tool to replace Medusa. The project was conceived in June 2005, during a discussion in a private channel on how typesetting SHOULD be. The project was founded by ArchMage ZeratuL (Rodrigo Braz Monteiro) and jfs (Niels Martin Hansen), with support from Mentar and maxx-. Soon, the project escalated and drew new members in.The program was originally called "Visual SSA", showing its intention to allow typesetting to be more visual than guesswork. It was soon renamed "Visual ASS" for the pun, and, sometime during alpha stage, the name "Aegisub" was picked. Aegisub is the contraction of "Aegis" (the goatskin shield of Athena in the greek mythology, whereupon Medusa's head was placed after she was slain by Perseus) and "sub" (for subtitles). Influence of the original name can be seen in the program icon (a red hexagon with an Eye, although this can also be interpreted as Aegis with Medusa's eye). The shortening "Aegis" is discouraged - "Aegi" is preffered.Soon after the first public release, due to popular demand, Aegisub incorporated much of Substation Alpha's timing system. The audio system has since been refined further with each version.Here are some key features of "AegiSub":
