examples
The command
avisync -i my_file1.avi -o out.avi -n -10
puts 10 audio frames at the beginning of the AVI-file.
E.g. if the audio is delayed about 200 ms (0.2 seconds) and
you’re working with a 25 frames per second AVI-File, you need to
shift the audio 200/40 = 5 frames since one frame is 40 ms long.
