Sometimes when you are in the middle of an action thriller film, your nerve tense, face stern and you are ready to enjoy the thrilling denouement. However, you are dragged back into the reality as the audio delays - the sound lags behind the video. You are not alone. Many users have been bothered by the similar video/audio out-of-sync issue, here is one cry from them:
Is there a way to resync audio when the video and audio don't match? In some video files the audio is like a second behind or ahead, and that's really annoying. Can you like press a button to make the audio jump ahead or back a few milliseconds, or something like that? — from VideoLAN Forums
Honestly speaking, audio/video asynchronous issue happens from time to time. There, two main reasons are responsible for the problem. Firstly, the file itself is out of sync which counts for one possible factor. Secondly, the frame rate's change while editing or during video format conversion process is the other possible factor.
Sync Audio in VLC Media Player
To sync audio in VLC media player, you need to do the followings:
- Step 1. Open VLC media player.
- Step 2. Click Tools on the top menu you will see the go-down list and move to Preferences at the bottom list.
- Step 3. Click the Audio tab and check All in the bottom to see the extent audio preferences.
- Step 4. Find the Audio desynchronization compensation in the audio preferences. Then you can set it either in positive or negative way. For example, if your audio is playing 1 second ahead of video, enter negative -1000 milliseconds in the box; if the audio lags 1 second behind the video, press positive +1000 milliseconds in the box.
- Step 5. After the correction is done, click the Save button in the right corner to match up audio track with video track.
Some users reflect that even though VLC media player can fix the asynchronous issue, it is only working well on the PC. However, those changes are not permanent:
I use an external HDD to watch some programme on my TV. These are stored on my PC. I fixed some out of sync subtitles using the advice you offer and it works perfectly on the PC using VLC media player. However the changes are not saved and once it is transferred to the external HDD they are out of sync again. Can you please tell me how to save the changes permanently. - from VLC Help
