How bilingual subtitle splitting works
SRT captions contain an index, start and end timestamps, and one or more lines of text. PairSRT examines the text in each cue, keeping the same timestamps in the output tracks.
The tool recognises Han characters and Latin letters. It works best when the languages are on separate lines. Simple mixed lines with a clear space between the languages are also handled. If a line is ambiguous, it is retained in both outputs and flagged for manual review.
This tool does not translate text. If your file only contains one language, it cannot invent the second language.
Common questions
What if the languages are on the same line?
Simple Chinese-then-English or English-then-Chinese lines separated by a space can be split. Complex mixed sentences are preserved in both files for manual review.
Will I lose the timecodes?
No. Every retained subtitle keeps its original start and end times.
Does this work with ASS files?
Not in this version. Convert your captions to SRT before using the splitter.
