Timing offset tool
When subtitles are uniformly early or late - because of an intro card, a format conversion, or a trimmed opening - you need a constant time shift rather than a per-cue speed correction. Paste your SRT content, enter a positive or negative millisecond offset, and download the adjusted file.

Questions
Time shift applies one constant offset to all cues - useful when everything is uniformly off. The timing fixer adjusts playback rate or stretches individual cues to handle uneven drift.
No. If a shift would push a cue before 00:00:00, it is clamped to zero. Cues that collapse entirely are flagged.
Yes. Paste VTT content and the tool parses both formats. The output defaults to SRT but you can convert with the SRT to VTT tool afterward.
Play your video, note when the first spoken word begins, then compare it to the first subtitle timestamp. The difference in milliseconds is your offset value.
