ASS (Advanced SubStation Alpha, with SSA as its ancestor) is the styled subtitle format of fansubbing — fonts, positions, colors and karaoke effects.
Typical use: Converting ASS to SRT strips styling for players that only accept plain subtitles.
About the ASS format
ASS (Advanced SubStation Alpha) is the subtitle format of the fansubbing world, descended from SSA. Where SRT holds plain text, ASS holds a full styling script: fonts, sizes, colors, outlines, exact positioning, rotation, fade-in effects and even karaoke timing — everything a subtitle needs to look designed rather than typed.
That power is also its portability problem: players that don't implement the renderer show ASS subtitles stripped to bare text, or not at all. Converting ASS to SRT keeps every line and timestamp while deliberately discarding the styling — the right trade for devices that only speak plain subtitles.
