Aegisub is an advanced multi-platform subtitle editor that is also ideal for creating lyrics for karaoke songs. Unlike many programs of this type, it offers much greater functionality. In addition to determining what text and for what period of time to be displayed on the screen allows you to format it freely and impose interesting effects on it.

Aegisub allows you to bold inscriptions, add borders to them, color them, set their specific position in the image, get a mirror effect and much, much more. Such extensive editing capabilities are possible thanks to the ASS (Advanced SubStation Alpha) format natively supported by the tool. Aegisub also offers many options to improve subtitles creation and editing - e.g.

video preview, which allows you to track the effects of your work directly from the program window.
