Qualify the job before execution

Subtitle Sync works best after you know whether the issue is a fixed offset, progressive drift, or a mixed timing problem.

  1. Identify the timing pattern

    Confirm whether the subtitles are always early, always late, or drift further out over time.

  2. Use one browser-side sync pass

    Shift timing in the browser first instead of mixing cue edits, format changes, and manual fixes together.

  3. Normalize format only when needed

    Open conversion tools after timing only if the subtitle asset still needs cleanup for the target player.

Translate only after cue timing is stable enough that you are not revising text against drifting subtitles.

Open route

Open Bilingual Subtitles

Merge source and translated tracks after the timing baseline is already safe.

Open route

Open SRT to VTT

Convert to WebVTT after sync repair when the final destination is browser playback.
