What is a .ass file?
text/x-ssa
ASS (Advanced SubStation Alpha, .ass) is a feature-rich subtitle format that extends SSA with precise styling, positioning, fonts, colours, and animation override tags. It is the standard for fansubs and anime, and is rendered by libass in players like VLC and mpv.
How to use a .ass file
Use an example .ass file to test subtitle parsers and renderers (libass), style and timing extraction, and conversion to or from SRT, VTT, and TTML.

- ASS Subtitles (Advanced SSA)An Advanced SubStation Alpha (.ass) subtitle with a styles section and three timed Dialogue events — the styled format libass renders — carrying the same captions as the SRT/VTT twins.
- ASS — Karaoke Timing and Override TagsAdvanced SubStation Alpha using the features that distinguish it from SubRip: per-syllable \k karaoke timings in centiseconds, a full V4+ style definition with primary and secondary colours, and an \an override that repositions a line. Converting this to SRT necessarily loses all of it, which makes it a good test of whether a converter warns about that or drops it silently.
