What is a .SSA file?
SSA (SubStation Alpha) is a styled subtitle format, the predecessor of ASS.
- Did you know
- SSA was created by the SubStation Alpha editor in 1998 and was later extended into ASS.
- SubStation Alpha was created in 1996 by a developer known as Kotus for the anime fansubbing community that needed styled, positioned captions.
- Unlike plain SubRip, an SSA file can set fonts, colours, outlines and on-screen positions, making it suited to elaborate typesetting.
- An SSA file is organised into labelled sections such as [Script Info], [V4 Styles] and [Events], with each caption line written as a comma-separated record.
- A .SSA file is plain text, so you can open and edit it in any text editor.
- What Analyser shows you
- Parse subtitle cues and timing from SubRip (SRT), WebVTT, and ASS/SSA: cue count, on-screen time, and a full timed cue list.
- Open a .SSA file
- Drag a .SSA file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
