FAQ
Why are my subtitles out of sync?
Usually they were made for another cut or frame rate of the video. A constant offset is fixed by shifting; an offset that grows over time needs the two-point method.
How does the two-point method work?
Find one early line and one late line. Enter their times in the file and their correct times in the video; the tool applies a linear correction to all subtitles.
Is my file uploaded?
