VLC Subtitle Timing and Delay Calculator
Enter when dialogue is heard and when its subtitle appears. The calculator returns the correction in seconds, milliseconds and VLC keyboard steps.
Calculate the subtitle timing correction
Use HH:MM:SS.mmm, MM:SS.mmm or seconds.
Your subtitle correction
Compare the two timestamps to calculate the result.
Apply the correction in VLC
If subtitles appear late, advance them. If they appear early, delay them. VLC’s subtitle-delay shortcut commonly changes timing in 50 millisecond steps, so the calculated step count is an estimate you should verify against the picture and dialogue.
