Fix audio syncing problems when playing videos

Jun 3, 2010 - 3 Comments

Every once in a while you’ll come across a video that has audio syncing problems. Sometimes it’s minor where the sound track and dialogue is off by a few milliseconds and it’s barely noticeable, other times it can be off by as much as a few seconds and this makes watching the video almost impossible. Using VLC you can easily resync audio tracks to a video by either offsetting the audio forwards or backwards.

Fix audio syncing when playing a video file in VLC

* From the VLC menu, go to Preferences
* Click on the “Audio” tab
* Click on “All” in the lower left corner to display more audio preferences
* Look for “Audio desynchronization compensation” in the preferences
* Set the syncing compensation forward or backward, depending on how your audio is out of sync with the video
* Click “Save”

Remember that this is not permanent and that the resyncing will only effect the video when played in VLC. This method works on all video types supported by VLC, whether it be a DIVX AVI, MOV, MPG, or just about anything else that VLC will open. A common misconception is that there is an audio syncing problem when the video or audio itself doesn’t load at all, this is probably not syncing but rather a codec issue. If you run into this, learn to watch AVI video on the Mac using something like Perian that has a wide codec support. In most cases, VLC will play the movie files as well though.

    The F and G keys retard and advance the audio delay by 50 ms while you’re playing, saving you the above hassle.
