Why it gets the details right
TimingShift every line, or only from a cut scene on; sync by two lines when the drift grows; convert between 25 and 23.976 fps.
TextOdd symbols instead of letters are re-read in the right encoding; hearing-impaired notes, credits and site ads come out.
Two files into oneTwo languages on screen at once, matched by time — or part 2 of a film after part 1.
