Mkvtoolnix Gui Extract Audio Track How To Fix Some

In a previous post I wrote about how to fix some of these synchronization issues permanently using Avidemux, but since then I have received few complains of Avidemux not being able to fix those issues in some cases.

Avidemux can do very little if the input file itself has some issues (corrupted video frames etc) but Avidemux is also a bit buggy, so some of the blame goes toward it also.

In any case, there are few other tools that you can try while trying to fix a sync malfunction, and MKVToolNix is one among them.

Illustration MKVToolNix is not an encoder as you can only use it to extract audiovideosubtitle tracks from other containers (MP4, AVI, FLV etc) and put them into the powerful and open-source MKV container.

While doing so this tools also lets you pass certain settings (sync, fps, aspect ratio ) and it is through that we can attempt to fix sync problems.

But please be aware that the only output format it support is MKV (and few of its variations such as MKA for audio, MKS for subtitles etc) and unlike MP4 or AVI, MKV is not supported by a lot of commercial and strictly hardware based multimedia players.

Computer users however do not have to worry about it as popular players (VLC, MPC, PotPlayer, SMPlayer, KMPlayer ) support it.

Note: Make sure you have downloaded and installed the latest builds of MKVToolNix from here.

I also recommend that you use VLC because both these utilities are available for multiple operating system platforms, so you can use this guide in any of them.

First we are going to play the troublesome file in VLC (or any other player that lets you change the sync temporarily) and we will try to identify the proper sync value..

Then we will simply enter that sync value into MKVToolNix and save it as a new MKV file so that it is saved permanently.

That is it. Step 1: So open your troublesome file in VLC, and let it play for a few seconds.

This will make VLC play the audio track a bit ahead of the video.

A single click increases the value by 50 milliseconds only, so unless the gap is very small, you will have to press it a few times to get see its effect.

Anyhow, if after pressing j key for a few times it worsens the gap, then it is an indication that you actually have to make VLC play the audio track a bit behind (delay) the video.

Again, to feel its effect, you might have to press it a few times.

So keep doing that until you come up with the perfect sync value.

Once you have found it, simply take a note of it (note that depending on the file the value could be positive or a negative one.

If it is a negativeminus one, then you should enter a minus sign before entering the value in MKVToolNix, more below) and close VLC.

Step 2: Now open MKVToolNix and load the troublesome file into it.

Then under Tracks, chapters and tags field, select the audio streamtrack (shown below is an example).

Step 3: Then from under it, click on the Format specific options tab and you will see an empty field that says Delay (in ms).

Now simply enter the sync value you found above into that field.

Make sure to enter a minus sign (-) when needed (-200 for instance) Step 4: Now click on the Browse button under Output filename field.

If everything goes without any errors, try playing the newly saved MKV file and now you should be able to enjoy it without any lip-sync issues.

Good luck.
