Out-of-Sync Audio in VLC Media Player- Resolved


Out of sync audio can be one of the most irritating things when it comes to watching movies, music, and other interesting videos. Searching online, we found several people asked about fixing variable out-of-sync audio in VLC Media Player. And if you are facing a similar situation, today we're going to talk about three simple ways using which you can quickly fix the out of sync audio issues in VLC without breaking a sweat.

Method 1. Temporary Fix using Keyboard Shortcut in VLC

This is the easiest way to cope with VLC audio sync issue-use Keyboard shortcut. Which keys work? Watch below:

For Windows PC users: press the J or K keys to move the audio back or forward 50 milliseconds, respectively.
For Mac OS users: press the G and F keys while the video is playing in VLC. "G" moves the audio forward and "F" delays audio.

Here is an Audio delay indicator whose function is to tell you by how many milliseconds you have moved the audio forward or back after hitting the keys.

Applying keyboard shortcut to fix VLC audio sync problem is quite simple, right? But things are not always going perfectly. See, using the keys solely allows you to move the audio in increments of 50 milliseconds, remember milliseconds, not seconds. So supposing you wanna move it more precisely, then you'd better to resort to VLC's Preferences.

Method 2. VLC's Preferences to Sync Audio with Video in VLC

Steps to fix video audio synchronizing problem in VLC with VLC's preferences.

1. Launch VLC and find Preferences from Tools option at the top of VLC interface menu.
2. Click "Audio" and select "All" in "Showing settings" area in the lower left corner.
3. Find out "Audio desynchronization compensation" after double clicks on Audio and set the syncing compensation forward or backward, depending on how your audio is out of sync with the video.
4. Click "Save" and then the VLC audio sync task is finished. You can eventually play the video with video audio in synchronization and finally liberate yourself from the annoying audio out of sync issue in VLC.


Method 3. Permanent Fix VLC Audio Sync Issue

Generally speaking, applying keyboard shortcut or VLC's preference can fix the usual audio not syncing with video problem in VLC. But everything happens for a surprise. Here we also worked out two other options for you to fix VCL audio sync problems permanently.

A. Using Avidemux

After you have installed Avidemux and launched it, import the video to it. Having done that, you will see the option Copy under the Video and Audio Output. If you want to change the output format, you can click on the drop-down and select the desired format, but if you want to proceed risk-free, just keep the settings as Copy.

Finally, to change the audio latency, check the Shift option in Audio output and enter the value in milliseconds (1000 milliseconds = 1 second). Enter a negative value if the audio is coming before the video.


Once everything is in place, choose the final output format and then select the option Savefrom the File Menu. It might take some time for the app to render the final video after which it can be played on any player without audio sync issues.
