How to sync subtitles

  1. Open your .srt or .vtt file, or paste the subtitles.
  2. Enter how many seconds to move them: a positive number makes them later, a negative number earlier.
  3. Download the fixed file.

Good to know

  • Find the right value by noting when a line is spoken in the video and when its subtitle appears.
  • If subtitles start in sync but drift more and more, the frame rate differs: use the frame rate fix.
  • Subtitles moved to before 0:00 are removed; one that is only partly before 0:00 starts at 0:00.

Veelgestelde vragen

Can it fix subtitles that drift over time?

Yes, when the drift comes from a frame-rate difference (23.976, 24 and 25 fps). Choose the matching frame rate fix.
