Subtitle Timing Tools — Sync, Merge, Check & Repair
Timing is where subtitles go wrong, and where the fixes are maths rather than magic: a constant offset for a uniform delay, a linear stretch between two sync points for drift, a frame-rate conversion for the PAL-speedup family of errors. Beyond fixing, this group covers merging — two parts into one file, two languages into one bilingual track — and the viewer that opens any subtitle file as a clean cue table with the five checks that explain most "captions look broken" reports, each with a one-click repair.
