So what's the reason for the effect not occurring on full width shots with no gain?
Does the 2.1's sensor suffer from the same effect?

I am a bit confused - are the described changes in the "standard" GUI also availabel or only in the "new" GUI, which is no longer being developed.

BTW I have the same problem like ieSe - I tried to setup smb like in the description and get the report 'DESKTOP-XXXXX is not reachable!'

I haven't used the new UI in a while, but I think the new UI's network menu won't let you use it at all until you set a password on it. I believe it sets the root password for ssh for both the USB and ethernet connections.

There are 2 buttons beside the text box on the App & Internet access screen. Either enter your own password, or tap the button with the dice on it to generate a random password. The network accessible features should be displayed once you have a password and tap the button with the diagonal lines.

Thank you skronstein for your replay. I installed the software V0.4.0 Beta again without applying the new UI. I tried the instructions but it didn't work. Here is the error "Mount Failed: mount: wrong fs type, bad option, bad superblock on //192.168.0.102/smb, missing codepage or helper program, or other error (for several file systems (e.g nfs, cifs) you might need a /sbin/mount.<type> helper program)". I think this is a problem with sharing files between Linux and windows.

Hardware Setup
  • My laptop is connected to the router through wireless network.
  • Chronos 1.4 is connected to the same router through the Ethernet cable.
My laptop is running Windows 10 Home. You can find my network sharing settings in images.
I thought that smb file location address might differ from the instructions file, so i tried these addresses but none of them works too.
In Mount tab:
  • smb
  • \\DESKTOP-23CTSB5\smb
  • \DESKTOP-23CTSB5\smb
  • DESKTOP-23CTSB5\smb
  • //DESKTOP-23CTSB5/smb
  • /DESKTOP-23CTSB5/smb
  • DESKTOP-23CTSB5/smb

Did i make something wrong?

Hi, just to follow up on this. The latest updates to the unstable branch should now have resolved some of the issues that we found in the SMB mounting code. In particular there were two bugs that you were likely running into. The first was that shares requiring a username and password were failing due to an error in the setting of the mount options, and the second was that cameras were missing some support packages that would enable name resolution. To get these fixes, you will need to ensure you have software build 0.4.0~beta38 or newer, as shown on the About tab of the Util window.

I have attached some screenshots of how I have configured my camera so that it is able to save footage to a Samba share on my Windows 10 PC. Note that the layout of the network settings window has changed slightly between voyager and unstable.

The first step is to share a folder on your windows 10 PC, and ensure that SMB 1.0/CIFS file sharing support is enabled. In this particular case, my username on this windows 10 PC is "Owen" and I am the owner of this share.

We can then configure the camera to use this share via the Network tab in the Util window, and then hit Apply to mount the share and make it permanent.

After this, the network share should appear in the Storage tab of the Util window when successfully mounted.

And it should be available as a storage device when saving video.

Hi, I installed chronos-unstable-20200328.img and also chronos-voyager-20200331.img, but i got the same error 'DESKTOP-23CTSB5 is not reachable!'. Here are my steps to configure the smb file:
  • For Windows:
    • control panel -> programs -> Turn windows features on and off -> check all boxes for SMB 1.0/ CIFS
    • Make new folder "smb" in drive c:\ -> right click on it -> choose "sharing" tab -> click on share -> choose owner -> click share
    • to get my username correctly I opened cmd -> type (echo %username%) then enter

  • For Chronos 1.4
    • MSB Share: (//DESKTOP-23CTSB5/smb)
    • Username : I typed the username that i got from step 3 in Windows steps
    • Password  : I typed the Password, that i use to login in to my laptop

We have pushed some updated software to the voyager software release, which should hopefully address some issues that you have reported, and improve the usability of the camera's software. You can access these changes using the Software Update tool found on the Storage tab of the Util window, and then downloading updates from the package repository.

Major Changes from chronos-voyager-20200302.img.xz to chronos-voyager-20200331.img.xz
  • Improve exposure slider latency by using a different RPC transport when adjusting exposure (JSON-RPC).
  • Report the last shutdown reason on the About tab of the Util window to help explain powerdown reasons.
  • Reduce minimum vertical resolution to 32 pixels on the Chronos 1.4
  • Fix math errors and improve error reporting in for auto white balance
  • Redesign the static IP address widgets on the Network tab of the util window
  • Enter recovery mode when both the record button and encoder wheel are pressed at boot.
  • Fix errors in SMB mounting options when share is specified with a NetBIOS name, or a password is required
  • Support for FUSE filesystems
  • Significant changes and improvements to the HTTP user interface (we now consider this ready for use).

chronos-http: 0.4.0~beta17 -> 0.4.0~beta54
  • Disabled buttons and menu items that don't do anything right now for release to users
  • Added step sizes to the offset values in the resolution box. Technically, any vertical offset will
        be accepted, but that throws the colors off. Also, the horizontal offset snaps to the next-lowest
        value in increments of 16, so often it is not exactly centered, but this is a compromize so that
        the calculation to center it is easier; once the apply button is pressed, it snaps itself to an
        acceptable value.
  • Changed sliders and number inputs to be more responsive This includes changing the start / end
        frames while dragging the timeline / start marker / end marker around Also now support scrolling /
        quickly typing / using the up/down arrow keys inside number input fields
  • Made sliders and numeric inputs continuously updatable The checks and communication with the camera
        are done while the number is changing. To prevent this from sending too many requests, a new
        request can only be sent once a previous one has returned.
  • Fixed the offset and centering calculations to work with different sensors I was just using
        hard-coded constants for the horizontal and vertical resolutions before, and then I forgot about
        them. Now, I've replaced the constants with values that come from the camera itself.
  • Started adding pop-up / overlay messages Pop-up / overlay messages are needed to give the user a
        chance to save their footage if they forgot to save it, to give the user some information, and to
        notify the user if the camera is unreachable. I have started to add the capabilities for these
        messages, but they are not implemented yet.
  • Cleaned up some timing, themes, sizes, etc.
  • Added transparent / no border property for :-moz-range-track so sliders look right in firefox
  • Added some limiters for number inputs so that they can't go outside of the min / max values
  • Detect when using Edge / IE and use different style-sheet and change "onchange" to "onmouseup" for
        sliders
  • Made the 'onchange' property get replaced by 'onmouseup' when using Internet Explorer so that it
        doesn't overload the camera and cause the webserver to fail
  • Fixed record / play bar height differences across browsers
  • Worked on cross-browser compatibility (IE, & Edge mostly, some Safari) Did a lot of re-styling of
        the sliders and other elements to fit and work properly Also added some additional checks and fixes
        so that the javascript runs on all browsers
  • Added support for browsers that don't do server sent events Also updated the menu behaviour and
        fixed its z-index Tried to add slider styling changes for Microsoft browsers
  • Moved the colors into separate theme files and adjusted the colors to match the themes Also added
        control for the video state (play mode vs record mode/live display) to navigation menu dropdown
  • Changed the font source The fonts are now stored on the camera so it should show up correctly no
        matter whether or not the user has an internet connection.
  • Adjusted spacing, styling, font position, and look on different browsers
  • Started to split styling out into css files Also fixed the timeline sliders on chrome
  • Adjusted functionality, behaviour, and look of Play&Save screen Dynamic sizing (screen width) has
        been set, and some of the blocks resize so that they look nicer at certain screen sizes.
        Downloading from the camera now works for image files that are in folders.
  • Added play&save screen functions like save to and download from camera More advanced settings can
        be configured for the filesave (bitrate, fps) The current frame, starting frame, ending frame, and
        length of clip can be manually entered
  • Added feature to download videos from the camera Added some number fields in a few places, but they
        don't do anything yet. Split the "Save Video" block up; the "Storage Device" dialog is now its own
        block. I also  made the "play" button switch the video system into playback mode if it's in record
        mode, though that may have been undocumented in a previous commit.
  • apidoc: Refresh parameters when clicked.
  • Rename startAutoWhiteBalance to startWhiteBalance
  • Add Krontech logo to the API documentation
  • Move parameter value column to an collapseable button.
  • apidoc: Use parsed docstrings for params, add method dropdown.
  • Added timeline, start frame, end frame control and it now saves according to those settings
  • Fixed icon active colors
  • Added a catch for non-usable resolutions so that different sensors can be used
  • Added start and end frame sliders and a fill between them
  • Added new 'Play and Save' screen. I also added links to go betwen the main screen (record screen)
        and the play/save screen in the top navigation bar.
  • Made page layout responsive Made things look nice across various screen sizes. Also made some
        changes to some of the spacing.
  • Save files, display save progress, display whitebalance overlay, display video state
  • got rid of the need for the 'screenShots' folder and its contents
  • Added a folder for writing the screenshot(s) to
  • Added a lock to accessing the screenshot, and changed the permissions of the file
  • Fixed icon highlight color problem. Also adjusted some sizing

Chronos User Discussion / Re: Issue with horizontal darkening w/ bright things
« Last post by foobar on March 29, 2020, 10:38:08 PM »
This is a known behaviour of the LUX1310 image sensor that powers the Chronos 1.4. It occurs under conditions of extreme overexposure which appear to degrade the sensitivity of the entire line as it is digitized. This is an analog characteristic of image sensor, and we don't have any way to avoid it other than to reduce the exposure or aperture until the image is no longer clipping.

Chronos User Discussion / Issue with horizontal darkening w/ bright things
« Last post by Prehistoricman on March 29, 2020, 03:27:33 PM »
I've had this issue on my Chronos 1.4 since I got it. If there is a dark-ish scene with a bright light source/object, everything in the horizontal band of the highly exposed area gets darkened.
Here's a video to showcase the issue (see 10s and onwards):

https://www.youtube.com/watch?v=E7BHrx0BAM4

This was probably shot at 12dB gain on v0.3.1 firmware, 1024x576. Standard issue Computar lens.

I've done some testing to determine at what settings this does and doesn't happen:
1280xanything: Only happens with >0dB gain
All other resolutions are affected by this at 0dB and other gains.

Black cal doesn't seem to influence it.

Is this an issue with all 1.4s? I haven't seen anyone else here complain about it.

This is probably the best clip that I have ever shot with Chronos cameras https://youtu.be/EuiUnfsKLJ8?t=423

It's 1000 fps and so good it's hard to tell apart from Sony A6400 clips that we have on the same video. Lens is 50-100 f1.8 Sigma zoom and I think it wasn't wide open with this one
