For example, enter 2.5 to move the selected cues 2.5 seconds later, or −1 to move them earlier.
Different movie release formats, frame rate discrepancies (23.976 fps versus 25 fps), or introductory studio logos often cause external subtitles to lead or lag behind speech. Instead of re-downloading dozens of mismatched files, BuzzyTools lets you mathematically shift all cues forward or backward by your exact offset in milliseconds.
Add a positive delay (+ms) when subtitles reveal punchlines and plot twists before the characters speak.
Apply a negative delay (-ms) when dialogue has already concluded before subtitles show up on screen.
Correct constant 5 to 15-second offsets introduced by streaming platform bumper clips.
Permanently fix subtitle timings for USB flash drives and TV media players that lack sync sliders.
Pause your video when a character speaks a distinct first word, note the video timestamp, check the subtitle's starting timestamp, and subtract the difference.
Yes, you can enter negative values to shift subtitles backward if they are appearing too late.
Not at all. The parser only recalculates the numeric timestamp lines, leaving all text cues and formatting 100% intact.
Yes, our sync engine preserves UTF-8 encoding so Arabic, Hebrew, and Persian subtitles remain perfectly formatted.
