The rule of the thumb is that, if the audio is played before the video, then that means we have to ‘add time’ to it (thus delaying it), so the video track can ‘catch up’ with the audio track. If not, click on the ‘Play’ button on ‘Avidemux’ window, so we can observe and see whether the audio comes before or after the video scenes. Now, if you know what the correct audio/video sync value is then you can skip this and go directly into the end of ‘ Step 5‘. Also make sure to enable the option called ‘Shift’ (disabled by default), as it is the option that lets you change the audio/video sync setting (shown below).Īny value that you enter here (‘Shift’) should be in milliseconds (1000 milliseconds = 1 second). Now open ‘Avidemux’ program and load the ‘troublesome’ multimedia file into it.īefore continuing, under the ‘ Video Output‘ and ‘ Audio Output‘ options, make sure it says ‘Copy’.

I just added this ‘update’ just to give some confidence to the readers.įirst of all, go to this page, download the package and install it (it has pre-built packages for Windows, Mac OS X and GNU/Linux).

Update (): Yes it’s been more than four years since I originally wrote this post (yes, even so, I update it from time to time), but the instructions still work. If this method fails, then I’ve added another method that guarantees results in most situations at the end of the article as well. While the results are not always guaranteed, ‘Avidemux’ has a good track record.

So if you’re having lip-sync errors in one of your multimedia files, then you can try the below ‘Steps’ for a possible fix.

‘Avidemux’ also supports multiple operating systems, therefore you don’t have to be only a Windows user to use it either.

‘Avidemu’ is actually one of the best free audio and video synchronization software that you can use (it’s originally intended purpose is actually to act as a simple video editing & encoding software which comes with in-built filters etc). And the good news is that you don’t have to buy a premium software utility, because thanks to a great (and free) open-source tool called ‘Avidemux’, you can save the audio & video out of sync setting permanently for a lots of video & audio codecs (HD, Blu-ray or even 4K videos!) and container formats (MP4, MKV, FLV, MPEG, AVI etc). Therefore, the most ideal solution is to use a video syncing (synchronization) software to fix it. The problem with that method however is that it only saves the sync setting temporarily, and it will be lost the next time you play it. In any case, the good news is, depending on the OS platform that you are using, there are powerful software multimedia players (VLC, KMPlayer, MPLayer etc) that give you the ability to manually adjust the sync (video or audio) setting, thus you can enjoy the multimedia files without such issues. If it’s hardware based, you should be looking elsewhere. But this method that I’m going to show you, only works if the sync problem lies with the multimedia file. Sometimes syncing issues are also caused by audio hardware devices (sound cards, amplifiers or even buggy headphones etc). This is a pretty common issue in multimedia files and there are many reasons behind its existence, but for keeping the article clear and simple so that anyone can understand its context without having to go through boring technical details, I will not mention them. If the synchronization value is incorrect, then the audio (or the video) is going to be played early or with a delay, compared to the other, which is commonly known as ‘lip-sync’ errors, and it jeopardizes all the excitement, obviously.įor instance, while watching a movie, if you have ever come across situations like gunshot firing sounds coming out before its video scene is displayed, then that is due to an improper audio to video sync. ‘ Audio to video synchronization‘ is an extremely important aspect of a multimedia file, because when playing, multimedia players rely on it for properly synchronizing the audio and the video tracks.
