What is a .ssa file?
text/x-ssa
SSA (SubStation Alpha, .ssa) is the predecessor of ASS: a styled subtitle format with a Script Info header, a styles section, and timed Dialogue events. It supports fonts, colours, and positioning, and remains widely readable even though ASS has largely replaced it.
How to use a .ssa file
Use an example .ssa file to test subtitle parsers, SSA-to-ASS upgrades, and conversion to SRT or VTT, or to exercise styled-subtitle handling.
