It is simple to make a video with multiple audio tracks, sample.mp4 is a video file without any audio tracks in it, add two audio file, each for one track:

ffmpeg \
-i sample.mp4 \
-i lang1.mp4a \
-i lang2.mp4a \
-c:v copy \
-map 0:v \
-map 1:a \
-map 2:a \
-metadata:s:a:0 title="lang1"  \
-metadata:s:a:1 title="lang2"  \
-y \
video_with_multi_audio.mp4

How can I do it with Kdenlive or other video editor?

I don't know about Kdenlive, but for example in DaVinci Resolve you can:

  1. Enter Edit mode with your video added to timeline.
  2. Drop lang1.mp4a into audio timeline, so that it looks more or less like this:

Audio timeline

  1. Right mouse click on the left side of audio timeline where e.g. Audio 1 is on the screenshot. Choose Add Track with preferred option:

Add track menu

and then drop the 2nd file onto it. Alternatively, you can drag and drop lang2.mp4a below the first track and 2nd track will be automatically added with default parameters.

  1. In Deliver tab ensure that a container that supports multiple tracks is used, such as MP4, then in Audio subtab add all the Output Tracks that you want to include.
