SSA to SRT

Convert old SubStation Alpha (.ssa) files to SRT

SSA is the older sibling of ASS and still turns up in archives. Captionry reads its [V4 Styles] and [Events] sections and writes plain SRT that any player accepts.

How to

How to convert SSA to SRT

  1. Drop your .ssa files

    Drop files or a whole folder onto the converter. Each file is checked and listed with its encoding and cue count.

  2. Keep SRT selected

    SRT is preselected on this page. Set a time offset or strip tags under Options if you need to.

  3. Save the result

    One file is saved as .srt; several come as one zip with your folder structure kept.

Details

What changes in the conversion

  • The Events Format line decides which field is the start, end and text, so SSA's Marked field and custom orders are read correctly.
  • A style with Italic or Bold set (-1 in SSA) makes that style's lines italic or bold in the SRT.
  • Inline {\i1} and {\b1} codes are kept as <i> and <b>; positions, colours and fonts are removed.
  • Files from older Windows tools are often not UTF-8. Encoding is detected, and you can choose it under Options.

FAQ

Questions

What is the difference between SSA and ASS?

ASS (v4.00+) extends SSA (v4) with more style fields and layers. Captionry reads both and treats them the same way for conversion.

My SSA file shows wrong accents. What do I do?

Pick the file's encoding under Options, for example Windows-1252 for Western European or Windows-1251 for Cyrillic. The SRT is always written as UTF-8.
