Caption Fit Lab

SRT timing fixer

Shift every cue and trim overlaps, then export SRT.

What it does: Shifts every cue, trims overlaps, and exports SRT / VTT / other caption formats.

What it does not: Does not re-time from audio. Review splits before you publish.

Limits: Trimming keeps cues at least 80 ms. Work stays in this browser.

    Trimming sets the earlier cue to end 1 ms before the next start, and never shorter than 80 ms.
