Subtitle Resync & Cleaner

How it works

SRT and VTT share the same underlying structure once the decimal separator (comma vs. period) is normalized, so one parser reads both. Shift adds a fixed number of milliseconds to every cue's start and end time; Stretch multiplies every timestamp by a factor, which is what actually fixes frame-rate drift (for example, 23.976 ÷ 25 = 0.95904 corrects the classic film-to-PAL mismatch); and the sound-tag stripper removes anything inside [brackets] or (parentheses), dropping any cue that becomes empty as a result.

FAQ

What stretch factor fixes 23.976fps subtitles synced to 25fps video?

23.976 ÷ 25 = 0.95904 — multiplying every timestamp by that factor corrects the common frame-rate drift between film-sourced and PAL-television-sourced subtitle files.

Will stripping sound tags remove any of the actual dialogue?

No — it only strips text inside [brackets] or (parentheses), like [MUSIC PLAYING], and removes a cue entirely only if nothing but a tag was left in it; ordinary spoken dialogue lines are untouched.
