Questions
How do I know how many seconds to shift?
Play the video, note when a line is spoken and when its subtitle appears, and enter the difference. Use a minus sign if the subtitles appear too late.
What if only part of the file is out of sync?
Use the Partial Subtitle Shifter to move a range of cues, or the Frame Rate Fixer if the delay grows steadily through the video.
