How to easily convert an MKV video to an MP4

Question

I would like to easily be able to convert a MKV video to MP4 video in Ubuntu. Is there any way I can easily do this at all?

Answer 1

One easy way (requiring a terminal), is using FFMPEG.

First, open a terminal and install FFMPEG with this command:

sudo apt install ffmpeg

Now all you have to do to convert your video is this one single command:

ffmpeg -i <inputfile> <outputfile>

For example, in your case:

ffmpeg -i input.mkv output.mp4

FFMPEG will automatically detect/use the correct input and output formats.

Conversion may take a few minutes based on length and frame rate of video.

Answer 2

As a GUI for ffmpeg there is this tool: dmMediaConverter.

Very easy to use, but with subtitles I had to edit the subtitle codec and change to mov_text.
