HELP - .mvk to .mp4 audio-layer problem

[Sanzee]

What's up,

I need some help converting a video file with multiple audio tracks, to a new file using only one of the forementioned tracks. I recently downloaded several episodes of a TV show. The video files are in .mkv format; I use MPC to view them. In each video, or episode, there are three distinct audio tracks (or layers) available to choose from.

1. English vocals/Japanese music
2. Japanese vocals/Japanese music.
3. English vocals/American music.

Now, of the 3 audio tracks available, I only need the third one; Yet it is not the default track, so when I open up AVS and convert the episodes (.mkv to .mp4), then play the converted file I discover that the audio is... surprise! The .mkv default audio track. I obviously knew this would happen. What I didn't know was that it would be so difficult to convert a video that has multi-layered audio into a video with specified-layer audio. AVS Converter has few advanced features. Xillisoft Video Converter has more, but I don't have enough experience with expert features. To break it down, I basically "need to convert a .mkv file (with three seperate audio layers) to a new video file (with only one of the three original audio layers). Is there a simple solution to this problem? Is there an extraction technique? Or is it possible to remove specific audio layers from a video file, leaving only the needed audio track behind?

Forgive me for the length of my post, I am just eager to find a solution. I look forward to your response.

you can use a program called mkvextract to break down your mkv file into a video and 3 seperate audio files then you can make a new mkv using megui including only the video and the audio file you want.

Don't use mkvextract, or you might get sync issues

I would use mkvmerge, checkmark streams you want to keep, uncheckmark streams you don't want, and make a "new" mkv

Alright, great, thank you so much for the responses. I'll get on them right away. Hopefully this works. If not, well... if anyone else has some ideas, please speak your mind. Thanks again.
