Extracting IR video from the CGO-ET

[Steve Carr]

CGO-ET
The 1080p and IR video are combined into a single MP4 video file. If you need to edit they can be separated.
Extracting the IR video from the MP4 file
I have finally got the solution from the VLC player forum.

Here is the link to the tool download:
MKVToolNix Downloads – Matroska tools for Linux/Unix and Windows


1) drag n drop your video file into mkvtoolnix -
2) uncheck the first video track
3) Press the 'Start multiplexing' button
4) Open the MKV file located in the destination folder. The MKV file contains the IR video track + audio.

When I tried the MKVToolNix I did not get 3 output files. See attached, Great tool though

Strange. There should be two video files and I also get 1 audio file. I'm using the -ET on the H so the firmware will be different if you are using the 520.
The file you dropped into the tool is the file from the -ET sd card?

Hi yes it is from the camera SD

The 520 or the H?

Ok. I'm going to move this thread to the 520 page. Perhaps it will get some attention from someone with both. I think there are some differences in the firmware.

I tried another few files and it worked. I got the three files and managed to separate the IR. I don't know why it did not work with the first file as it was shot on the same day and with the same settings. Cheers for your help.

Glad it's behaving. Okay.......back to work.........

@Steve Carr is this still the easiest method going for this process?

If you are using a Windows machine it's the only method I have found. It's fast and painless so I'm good with that.

In addition, is it possible to extract the raw binary data from the .mkv file (like in the Tiff images) which records the absolute temperature. All i managed to do so far is to get rgb values instead which visualizes the relative temperature.

As far as I know the data for the thermal images isn't stored. But I'm a novice with this camera.
