<p>I have an animated movie in three different languages. The picture is exactly the same for each langauge, only the audio is different.</p>

<p>I want to merge all these files into one, so that I have a single video file where I can switch easily between the audio tracks in VLC.</p>

<p>How can I merge the audio tracks into a single file?</p>

<ol>
<li>OS X</li>

<li>Windows desktop</li>
</ol>

@Mulvya I'm sorry, I just really want to find the solution to this. A different answer from what?

The one I gave. ffmpeg is pretty much the only tool that does this for most formats. If your videos are MKV, then [MKVToolnix](http://www.videohelp.com/software/MKVtoolnix) will also work.

@Mulvya I'm not comfortable with CLI. And for the the GUI options you linked to, I couldn't find the function. But I think I've found a way to do it though. The sources are all DVDs, btw.

@Mulvya Yes, MKVToolnix was very nice. Someone described it to me in detail here: apple.stackexchange.com/a/239676/153510

# Create video file with multiple audio tracks?

(Asked by: username_0 on 2016-05-26)

I have an animated movie in three different languages. The picture is exactly the same for each langauge, only the audio is different.

I want to merge all these files into one, so that I have a single video file where I can switch easily between the audio tracks in VLC.

How can I merge the audio tracks into a single file?

I can use any OS for the job, but my preferred order is:

1. OS X
2. Linux (Debian/Ubuntu/Mint)
3. Android
4. iOS
5. Windows desktop

It's not really important, though, I'll take suggestions for any platform happily.

The only function I really need is the merging itself. Lightweight solutions are a a plus.

I prefer GUI solutions.
