What happens when converting SSA to TXT?
SubStation Alpha content is parsed into a unified millisecond timeline before being exported as Plain Text. Valid timing and subtitle text are preserved.
TXT output removes every timestamp and writes each subtitle as one plain-text line.
Complex ASS / SSA style tags and positioning are removed while visible text and timing are converted.
Format overview
About SSA and TXT subtitle formats
Learn what each file format is, how it is structured, where it is commonly used, and what to consider during conversion.
Source file format
SSA · SubStation Alpha
SSA, or SubStation Alpha, is a classic advanced subtitle format and the predecessor of ASS. It supports styling, positioning, and effects, with SubStation Alpha v4 being a common version.
- File structure
- SSA files use sections such as Script Info, V4 Styles, and Events. Subtitle events are normally stored in Dialogue lines, and classic v4 files commonly include a Marked field.
- Common uses
- SSA is often found in older subtitle-authoring software, legacy subtitle archives, early anime subtitle projects, and players that still support SubStation Alpha.
- Conversion notes
- SSA and ASS are related but not identical. Text and timing can be preserved when converting to simpler subtitle formats, while complex styles and effects normally cannot.
Target file format
TXT · Plain Text
TXT is a plain-text file rather than a dedicated subtitle format with a standardized timeline. It usually stores subtitle, dialogue, or lyric text without information about when each line appears.
- File structure
- TXT has no fixed subtitle syntax and generally contains one or more lines of text. Individual files may include paragraphs, speaker names, or other manually arranged information.
- Common uses
- TXT is commonly used for video transcripts, dialogue editing, translation and proofreading, lyric extraction, and passing subtitle content to text-processing or AI tools.
- Conversion notes
- Exporting to TXT removes every timestamp. When converting TXT to a timed subtitle format, this tool treats each non-empty line as one cue and assigns it five seconds by default.
