Aegisub natively works with the Advanced SubStation Alpha format (aptly abbreviated ASS) which allows for many advanced effects in the subtitles, apart from just basic timed text. It has features to quickly edit subtitles, styling them and live video preview.

How to Install

I did not find any installation files- deb, rpm or even ppa for Aegisub. So, I had to compile from source and prepared a deb package.
