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.
