How to convert an MKV file to MP4 without re-encoding

This is a quick video that show you how to convert an MKV file into an MP4.

To do this I'm using a tool called Kirara, you can download this here:
Updated link here: videohelp.com/software?d=Kirara125.exe click the "Download Kirara125.exe here" link.

The original developer's web site doesn't appear to be around anymore so make sure to check all your downloads with a virus/malware checker.

This process is simply taking audio and video streams and moving them into a new container; the playback device will still need to support the original streams' format.

For playback on a computer I recommend SMPlayer smplayer.info/ or Kodi kodi.tv/

The method I'm using changes the container, or wrapper, of the video file; so using Kirara I extract the Audio and Video streams from the MKV and place them in an MP4 container.

No encoding is taking place so this is a very quick process.

Whichever device you are using to playback the file will still need to support the codecs for the video and audio within the file.
When you drag a file into Kirara the audio and video streams are displayed at the bottom of the window, in my case H264 (for video) and AAC (for audio).
