Open video using audacity and then edit->select all, then effect->change speed->enter value so the new length of audio will be equal to total time plus/minus the delay value.ģ.
Play video in VLC but this time determine the delay value near end of movie.Ģ.
#MKVTOOLNIX SYNC AUDIO MOVIE#
no delay in the beginning and as the movie plays it gets out of sync more and more, then you need to do the following assuming audio is sync in the beginning (you can always sync the beginning with above procedure) :ġ. wmv -vcodec copy -acodec copy -f matroska. Note: MKVToolnix does not accept wmv container file, so for wmv files you will need to need extra step to change wmv container to mkv container via the following using command line tool ffmpeg:įfmpeg -i. Remux the video, it will take only few mins since it is not a re-encode. If you also like to remove the annoying ads in the beginning, select the Output tab, then Split mode "after output duration" and enter the value of length of ad, Maximum number of files set to 2.Ĥ. Open video with MKVToolnix and select audio track, then enter the value in step 2 into the "Delay (in ms)" field, e.g if value in step #2 is -1.275, then enter -1275 here, or if value is 1.500 in step#2, then enter 1500 here.ģa. Usually do +1 or -1 secs increment to determine delay/advance, then adjust by 0.125 until fully in sync. Open "Track Synchronization window" on VLC and adjust while playing video until audio/video in sync. Need to be the same delta for this to work.Ģ. Play video with VLC player, check out of sync is constant from beginning to end.
