NAME

avisync - adjust audio synchronisation  

SYNOPSIS

avisync [ -o file -i file -q -n num -b num -a track -f commentfile ]  

COPYRIGHT

avisync is Copyright (C) by Thomas Oestreich.  

DESCRIPTION

avisync shift audio on frame basis.  

OPTIONS

-o name
Specify the name of the output file.
-i file
Specify the name of the input file.
-q
be less verbose.
-n count
shift audio by count frames. If count is positive, audio starts with audio frame count at the beginning of the AVI-file. If count is negative, audio is prepended count padding frames.
-a track
Specify the number of the audio channel to shift.
-b num
Specify if avisync should write an VBR mp3 header into the AVI file. Default is 1 because it does not hurt. num is either 1 or 0.
-f commentfile
Read AVI tombstone data for header comments from commentfile. See /docs/avi_comments.txt for a sample.
 

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.
