Align supplied translations to original subtitle timing. Review paired cues and export translated or bilingual SRT and VTT.
Create and export
Paste or open the original SRT/VTT and your translated SRT/VTT or blank-line-separated text.
Align by order or overlapping time. Select cues to edit translations; insert or remove empty slots to fix shifted blocks.
Resolve missing lines and download translated or bilingual SRT/VTT. Export CSV for further review.
Scope and limits
This aligns an existing translation; it does not translate text. Up to 2,000 original cues, 1 MB per text file. Plain translation uses blank-line-separated cue blocks, preserving line breaks inside each block. SRT/VTT translations can align by order or overlapping time. Review mismatches: timing overlap can assign a translation to more than one cue. Export requires a nonempty translation for every original cue. Original timings remain unchanged; bilingual text is limited to 2,000 characters per cue.
