SSA (SubStation Alpha v4) is the parent format of ASS — the same [Events] Dialogue structure with slightly fewer style fields. Every ASS parser reads SSA files.
Typical use: Convert SSA subtitles exactly like ASS — to SRT, VTT or plain text.
About the SSA 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.
