Syncing subtitles

A subtitle made for another edit, such as a TV broadcast, can drift out of time. Line it up against a video track, or pin two lines by hand.

Re-sync against, the first row of Tools, highlighted, with the video's own tracks listed beside it: ger, eng, spa, fre, ita, dut, pol, por, rus and vie, each marked subrip

  1. With a subtitle file on screen, right-click the picture, open Subtitles › Tools and point at Re-sync against.
  2. Pick any track, even a picture-based one.

The proposal: Re-sync French (TV timing), Lined up against eng · subrip, Speed +4.27% · made for another frame rate, Lines moved 26, by +4.39 s to +25.65 s, Match 100%, with Cancel and Apply

  1. Kaveo reads the whole video and shows what it would change.
  2. Click Apply or Cancel.
  1. In the subtitle editor, click a line near the start.
  2. Play to where it should appear and press Pin this line here.
  3. Repeat near the end, then press Fit the speed to the two pins.
  • The subtitle you are syncing must be a file, so a track inside the video has to be extracted first — see Loading subtitles. The reference can be any track, including a picture-based one.
  • Re-sync against is missing on a video with no subtitle tracks; the pins work there. On a Jellyfin title only a text track can be the reference.
  • Apply cannot be undone, and a high match only means the lines overlap the reference, not that each one landed right. Undo reverses a speed fit while the editor stays open.
