Chronos User Discussion / Speed booster St Chronos 2.1
« on: May 21, 2020, 01:17:24 AM »
Hello nice people, now that I understood what a speed booster is, I want to find out how to adapt such to a Chronos 2.1. I have a C-Mount to Canon EF adapter and want to attach my EF Sigma 24 1.8 Full frame lens. What do I have to do? I suppose I need a c-mount speed booster? I can't find such.

Thanks a lot! Martin

On my Chronos 2.1 this happens too sometimes. When things go bad, I have to restart the camera 5 or 6 times before it starts up. I am always running the newest "unstable" development releases.

Chronos User Discussion / Videos saved but gone
« on: May 18, 2020, 02:30:15 PM »

today I recorded some clips to a SSD connected via esatap. I saved as cinemadng. Now the camera seemed to save normally, I saw the frames being counted while saving.

When home again, none of the clips could be found on the disk. I recorded something again, as a test, and now the clip was saved.

Now I wonder how this might happen. Could it be, that the harddisk-handle had been lost after the camera has been booted? And could it be that the frames had been written into nirwana?

With regards to this: There was an announcement that it would be possible in future releases to review already recorded clips within the new GUI. When will this might become true, any guesses? Thanks!

Ok, sorry! I now made it work. Somehow I had a newer or at least different version downloadable from

However, my version did not support 12 bit RAW. Thanks!

Hello nice girls and guys,

I accidently recorded 12 bit RAW and really would like to convert the raw files to DNG, but I can't make it work. I recorded at full res 1000fps, newest software beta release "chronos-unstable-20200508.img".

Using " -C -w 1920 -l 1080 [filename.raw]" gives me sort of distorted image, don't know what that means. I attached a frame. Can anyone help me to rescue the footage? Thanks a lot!

Hello nice people. Just a question: Downloading a beta version here to Europe takes hours for me. I am quite sure this is because the beta-software is hosted on a subdomain directly on the krontec server. I am sure, there is no copy located somewhere here in Europe, thus one really has to download directly from krontec. This is very slow, I suppose there is no dedicated contingent for such a small server. It takes 14 hours for me, and I really have the fastest connection here. Also, I know that these connections to oversea servers are almost like peer-to-peer. So: Anyone knowing a faster location too? Like github or so?

Hello! Someone out there? Did anyone manage to setup a working network mount?

Thanks a lot!

Hello nice people,

I was trying to hook the camera to my computer, a Windows 10 machine. Now in this PDF is a guide to mount a network share on Windows, but I can't make it work.

First of all, just to be sure I do things right: I connected the cameras ethernet port directly to my computers ethernet port, is that ok?

If so:

On the "Network" tab in Utils there are three different control groups:

1.: Windows/SMB Network storage

Thats where I put the credential and the mount I created on windows. Now when pressing "Test" I get "SMB share CHRONOS on" is not connected. Of course is the fixed IP address for the adapter at my computer, CHRONOS is the user name. When pressing "Apply" I get: "Mount failed: mount: wrong fs type, bad option, bad superblock on // Missing codepage or helper program or other error....

2.: NFS Network Share

Did not try that

3.: IP address

Tried hitting "Make/Clear static IP". After that, I am able to ping the camera from the command line at the computer.

I'd really like to directly save footage over network.
What am I doing wrong? Any idea? Thanks!

I use a microcontroller to generate the ttl-signals to trigger both the camera on IO3 and the flashes one by one. It can trigger up to 48 flashes at a speed up to 12000 fps. I hope to do some tests with people soon.

The shoes are from my 3 year old son and you are right, its a flash array. Every single frame of the Chronos got its own flash. Running at 2142 fps the shoes fall down a very little, but nevertheless there has to be some Photoshop post. I suppose when running at 8000 fps or so the post isn't needed anymore. So I am awaiting the Chronos 5.5. The whole clip is made from just 12 frames.

Hello, thanks a lot. I'll order the correct plug, just to make sure I have a secure connection when on production with the camera. Thanks!

Hello, just asking to be sure I don't crash my camera: when connecting the camera to a PC via


this means I use an USB OTG adapter like  this one and then connect this adapter via a male-male cable to a USB-port of the PC? Never saw such connection yet. Will the PC then become the host?

Thanks! Martin
