<p>I just ran into this myself. I had a bad file called: <code>P1100020.mdt</code> from my Panasonic LUMIX GX85. The solution is to record a video with the same exact settings, then copy both to a Debian/Ubuntu box under Videos and run:</p>
<pre><code>sudo apt install git libavformat-dev libavcodec-dev libavutil-dev
git clone https://github.com/anthwlock/untrunc
cd untrunc
make
sudo cp untrunc /usr/local/bin
cd ~/Videos
untrunc -s  P1100021.MP4 P1100020.mdt
</code></pre>
<p>Keep in mind that <code>P1100021.MP4</code> is my working .mp4 with the same settings. That should spit out a working MP4 for those GNU/Linux users out there with a name like <code>P1100020.mdt_fixed-s1.MP4</code></p>

<p>&quot;Use the free software called untrunc. It is free and easy to use. It uses the corrupted MDT file and an uncorrupted MP4 file from the same camera to repair the MDT file. If it fails on the first pass it will suggest some options to get passed the errors.&quot;</p>

When Panaconic videocameras are abruptly interrupted while recording, the video is on the SD card as `.mdt`.

It's supposedly a video stream without a header and a footer.

How can I convert this to be an MP4 which the camera normally produces?
