Positive delays the subtitles (use if they appear too early); negative advances them (if they lag the audio).

💡 Fixes subtitles that are out of sync — shift everything earlier or later, and correct frame-rate mismatches with the speed factor. The format is detected and preserved. Everything runs in your browser.

✂️

If your video has a longer/shorter intro than the one the subtitles were made for, shift by the difference.
