- Isn't SSA just an outdated version of ASS?
- Yes — SSA is ASS's predecessor, with a smaller set of style fields. It's less common today, but some older encoding pipelines and editors still only accept .ssa specifically, not .ass.
- Should I use SSA or ASS if I have a choice?
- ASS, almost always — it supports more styling options and is what current tools default to. Convert to SSA only when something specific in your workflow requires that exact extension.
