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.
subtitles tips
If captions trail the speech, use a negative shift (e.g. −2s) to bring them earlier.
Find the delay by noting when a line is said vs when the caption appears, then shift by that amount.
Timings are clamped so nothing goes below 0:00.
