Subtitles out of sync?Fix the timing.
Move every subtitle earlier or later, or stretch them back in line when they drift. For SRT and VTT files, right in your browser.
Or paste the subtitles
Early, late or drifting?
If every subtitle is off by the same amount, shift them all at once. If they start in sync and slowly drift, they were timed for a different frame rate — choose both rates and they're stretched back into place.

Shift or frame rate: which do I need?
If the subtitles are early or late by the same amount from start to finish, shift them. If they start in sync and slowly drift, they were timed for a different frame rate: a 25 fps file on a 23.976 fps video runs about 4% fast, which is over two minutes off by the end of an hour.
How do I find how far to shift?
Note when someone starts speaking in the video and when the matching subtitle appears. The difference, in seconds, is the shift.
What happens to lines pushed before 0:00?
Lines that would end before the start of the video are dropped; one that only starts before 0:00 begins at 0:00.
Is my file uploaded?
No. It's read, fixed and saved by this page, in your browser.
