Why subtitles drift
Subtitles go out of sync for a handful of common reasons: the source video was re-encoded at a slightly different frame rate, a trim at the head shifted everything, or an automatic transcription mis-aligned by a few hundred milliseconds. All of these share the same fix — shift the timeline of every cue by the same amount.
This tool offsets every timestamp in your SRT or VTT in one pass. You set a direction (earlier / later) and an amount in seconds and milliseconds, and the output updates live. Cues are never reordered or merged.
Need to do more than shift? Convert formats with our SRT ↔ VTT converter, or hand the heavy lifting to Yond Captions in the YondCut Premiere Pro plugin — it transcribes, chunks, styles and places captions on your timeline.
