Aegisub (64-bit)

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 this tool) many vital functions, or were too buggy and/or unreliable to be really useful.

Since then, Aegisub 64 bit 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).
