How to use it
Paste or load an SRT or WebVTT file. Review any timing warnings before export. A positive shift delays captions; a negative shift moves them earlier. To make bilingual captions, supply a second subtitle file with the same cue count and matching times. Simplified and Traditional conversion changes writing, not language.
Before you export
Text-based subtitles only. Styling and positioning metadata are not preserved. Timing checks cannot confirm that words match the audio.
