Questions
Frequently asked questions
What offset fixes subtitles that appear two seconds late?
Use -2 seconds to move every cue earlier.
Can this fix timing that drifts gradually?
No. A single offset fixes consistent delay; progressive drift needs cue-by-cue or rate adjustment.
What happens to timestamps shifted below zero?
They are safely clamped to 00:00:00,000.
