Software Dev / Chronos V0.7.0 Full Release
« on: September 01, 2021, 12:36:59 PM »
Hey Everyone,

We're happy to announce a new release of software for both the Chronos 1.4 and Chronos 2.1 cameras. This version will benefit owners of both models, as we have improved save speeds and reliability, as well as image quality on the 2.1.

We spent more time setting up image validation tests, and working with some of our users in the field to determine ideal settings for the Chronos 2.1 image sensor, so we hope the benefit is extended to you in this update.

Additionally, the Network Update option is available again, so this should be a fast and easy update for anyone on version 0.6.x. If you perform an update by connecting your camera to the internet via the Ethernet port, and then accessing the Network Update feature accessible through Util -> Storage -> Apply Software Update -> Check for Updates, you will not need to re-calibrate your camera to continue using it as long as you were previously on 0.6.x. You may still use the Network Update function to upgrade from 0.4 or 0.5, but please see the Calibration section of the Release Notes to verify correct re-calibration after the update.

I'll summarize the improvements and changes here, but please also see the official Release Notes here:

New Features and Improvements

Save Performance and Reliability:
  • Save speed has been increased by up to 30%.
  • Stability while saving has been greatly improved.

Trigger/IO Settings:
  • Clarified some settings with "toggle" mode on the Trigger/IO screen. Now it
    specifies that it's only for buttons/switches and settings that should not be
    changed can't be changed when using this trigger function.
  • Trigger/IO screen now has a link to the trigger delay screen, and it will offer a
    reminder when using triggers if the trigger delay is changed from default (in
    case it was set accidentally).

Webpage Improvements:
  • Webpage has “zero-time” black calibration support (accessible from the menu
    at the top of the page). This feature allows for a fast black calibration to take
    place without the need to physically cover the image sensor.
  • Option for 'Digital Gain' added to the Main Screen / Homepage.
  • Some Chronos 2.1 color matrix options added to the webpage (for that camera).

Misc. Bug Fixes:
  • ‘Black Cal All’ doesn't crash the camera if certain specific trigger modes are
    used, nor will it set the trigger delay.
  • H.264 (mp4) files will not overwrite a previous file if a filename is provided
    (instead, it gives a warning that the filename was already used).

Chronos 2.1 Image Quality:
  • A previous software upgrade introduced a horizontal "shadow" when some
    areas were overexposed. This has been greatly reduced in v0.7.0.
  • Pink/magenta shift (especially in bright areas) reduced overall.

CinemaDNG Metadata:
  • All cameras formerly saved DNG images with metadata that indicated they
    were Chronos 1.4s, but this has been fixed. Chronos 2.1 cameras now say
    "Chronos 2.1" and Chronos 1.4 cameras still say "Chronos 1.4".
  • Color matrix settings are saved to DNG images now. Before, color matrix
    parameters in DNG files were always the same and ignored the camera's
    settings, but now the settings on the camera get saved in DNG files.

Known Issues, Updating Your Camera, and Calibration:
Please see the list attached in the Release Notes.

Updated User Manual and Datasheets
Please see either the 1.4 Resources or 2.1 Resources page on our website:

Software Dev / Chronos V0.6.0 Full Release
« on: February 08, 2021, 06:16:40 PM »
Hey everyone,

We're happy to announce a new release of software for both the Chronos 1.4 and 2.1 cameras. This version should especially be helpful to Chronos 2.1 owners, as our engineering team has spent even more time improving image quality and attempting to reduce vertical banding.

Something that's a bit different for this update is that you'll need to create an sd card image. We're having some issues with the package server, so the Util->Storage->Apply Software Update via network will not work for this update, but I still wanted everyone to have it instead of waiting for me to fix it. I'll come back and post when this update is also available via network update.

See for the update file, checksum, and a PDF of the release notes. Also contained in the PDF are instructions on how to update, and how to calibrate your camera, so hopefully that works as a start-to-finish guide for everyone. Please let me know if anything is unclear.

New Features and Improvements
  • Chronos 2.1 models benefit from an improved sensor driver configuration. The analog gain values of the LUX2100 sensor have been modified to reduce noise at higher levels of analog gain (also referred to as ISO), such as 6dB, 12dB, and 18dB. This translates to less vertical banding than in prior software versions. Adequate lighting is still highly recommended.
  • Chronos 2.1 models no longer require special factory calibration files. All calibrations required to use the camera with the best possible image quality can be performed by a customer in the field within 5 minutes via the Util -> Factory -> Column Gain Calibration function.
  • Chronos 2.1 models benefit from newly generated Color Matrix presets, as found in White Bal -> Color Matrix. Previous software versions had color matrices that were optimal for the LUX1310 sensor in the Chronos 1.4, instead of the LUX2100 sensor found in the Chronos 2.1.
  • A list of saved files on external media can now be browsed via Util -> Storage -> List Files. The same functionality exists to make it easier for users to select the save destination in Play -> Settings -> Pick Folder. The file browser also allows for users to delete files on external storage devices. This functionality is mirrored in the web page.
  • Monochrome cameras can no longer open Color Matrix settings. This was mistakenly enabled in 0.5.0.
  • Frame counts are no longer cut-off on the right-hand side of the display when in the Play screen when frame counts are six-digits long.

Known Issues, Updating, Calibration
Please see the PDF contained in the link above.

Chronos 2.1 Image Quality Change Demo
I've made a short video showing a before (0.5.1) and after (0.6.0) at HD with various analog gain levels. The main thing to note is the banding along the left and right sides of the frames in each shot, especially at 12dB. Please excuse the few spots of dirt on my engineering camera.
Download the video here: (I recommend downloading instead of viewing online because of the compression/loss of detail from streaming)

0.6.0 User Manual
We've also updated our user manual to reflect this update, as well as some general semantics. See:

Software Dev / Chronos V0.5.0 Full Release
« on: June 17, 2020, 05:16:58 PM »
We're happy to announce a new release of software for both the Chronos 1.4 and 2.1 cameras. This version builds on what was offered in V0.4.0.

I've attached the PDF of official release notes and upgrade instructions, but I'll reiterate them in this post as well. We'd be happy to hear about your experiences with this new version if you have a chance to update!

New Features and Improvements
● New Graphical User Interface with Dark and Light Modes
● Ability to set preferred exposure units on the main screen
● Double-tap video display area to zoom
● Ability to record live footage to H.264 mp4 @ 60 FPS in parallel with high-speed
recordings, including audio from the built-in microphone or line-in jack
● Automatic input detection and switching between the microphone and line-in jack
when recording audio in Live Record Mode
● Toggle Trigger Mode to allow BNC trigger to both START and STOP a recording
● Ability to configure most camera settings via the web page
● Ability to configure Triggers and I/O configuration via the web page
● Power Manager firmware update allowing for a longer button press (up to 3 sec.) to
boot the camera
● Power Manager firmware update to perform graceful shutdown when the battery is
critically low

Known Issues
● If the camera is being controlled via the web page, no messages will be shown on the
back-of-camera display if the video output mode is changed between
LIVE/RECORDING and PLAYBACK through the web interface.
● If the camera is powered on while connected to 10/100 (non-gigabit) network
equipment, the back-of-camera display will fail to start.
● When using Live Record Mode to simultaneously record 60 FPS MP4 footage to an
external storage device, the video display may momentarily blank or freeze while the
stream is being written to the storage device. This will not affect the high-speed

Updating Your Camera
There are two methods to update to Version 0.5.0. Please make sure to backup your work and calibration data prior to this.
1. [0.4.0 and later] Go to Util -> Storage -> Apply Software Update.
2. [0.3.2p2 and before] Re-flash your OS card by grabbing the image at: Please see the attached PDF for more details on this.
