Much of the software you guys are talking about will re-encode the video and audio thereby causing a little degradation in quality even at the highest settings. this tutorial is how to remove the audio and video from a mkv container and put it into a mp4 container. neither the video or audio needs to be re-encoded so no quality loss and it's done in about a minute and a half. I have used handbrake many times and it is great for encoding / re-encoding but it will not change container format without re-encoding WALTR also will transcode (re-encode) the file causing a little quality loss.

This is freaking genius and you are a star! I used to convert mkv video to mp4 video with Acethinker Video Converter, free and works perfect. It is a cloud based software to convert videos without install any software in your device. Share it here as an alternative method.
