About ASS

ASS adds styles to subtitles: fonts, colours, outlines, shadows, exact screen positions and animation effects. Fan-subbed anime and karaoke use it heavily. SSA is the earlier version, and the .ssa extension is read as the same format.

ASS styling is not understood by simple players, and it is lost when converting to plain formats. ASS gives full control over how subtitles look.
