Rescuing Dialogue from 1990s Subtitle Scripts
SubStation Alpha scripts encode dialogue inside an [Events] section with comma-delimited fields and possible inline override blocks. This converter reads SSA Dialogue lines, strips override blocks, converts SSA line-break codes to newlines, and joins the remaining text into a plain-text file. The result is a simple dialogue extraction for reading, searching, and reuse.
Input Format
SSASSA v4 (SubStation Alpha) is a subtitle script format with [Script Info], [V4 Styles], and [Events] sections. Dialogue lines use comma-separated fields, and override codes in curly braces can control rendering details. This converter reads UTF-8 input and can fall back to GB18030.
Output Format
TXTTXT is a plain text file with only the spoken dialogue extracted from SSA Dialogue lines. No override codes, no style definitions, no timing fields, no metadata headers. Just the words that were displayed as subtitles, in the order they appeared.

Frequently Asked Questions
SSA v4 (SubStation Alpha) is a subtitle script format using [Script Info], [V4 Styles], and [Events] sections. Dialogue lines carry comma-delimited fields and may contain inline override codes for styling.
The parser expects the standard SSA/ASS Dialogue field layout and takes the text after the fixed leading fields. Files with non-standard field order may not parse correctly.
It extracts text from text-based SSA files. It does not extract subtitles from DVD images and may not handle non-standard SSA field layouts.
The reader expects UTF-8 and can fall back to GB18030 for many Chinese-encoded files. Other legacy encodings may not be decoded correctly; convert those files to UTF-8 with a suitable editor before uploading.
SSA override codes in curly braces (such as {\fs24} for font size, {\c&HFF&} for color, {\b1} for bold) are stripped from the text. These are 1990s-era formatting instructions that are not part of the dialogue content. Only the actual words displayed as subtitles are preserved.
Drawing and other rendering instructions inside override blocks are removed with the rest of the block. Text outside those blocks is retained.
