Chronos User Discussion / Re: Continuous saving of single frames

Hello AIIS,
 
I just want to add a quick comment to David's reply.

You can use the Shutter Gating function. With it you can control the exposure time. The exposure time is set by the duty cycle of your input pulse.

This gives you the ability to freeze the motion of the propeller.

If your external device allows you to add a time delay, you can even record single frames of the propeller at different angular positions.

One way to test if your camera is functioning correctly is to use a lower frame rate. Here you can adjust the frame rate to your liking. The camera needs more light than a standard camera because it starts with a high frame rate by default.

Chronos User Discussion / Re: Sigma lens less price to alternate Sigma 24-70mm f/2.8 Nikon F zoom lens

« Last post by rocketsoak on January 15, 2024, 11:09:40 PM »

We have chronos 2.1 hd camera (Monochrome) do you have any other lens similar to Sigma 24-70mm f/2.8 Nikon F zoom lens.Since the price of Sigma 24-70mm f/2.8 Nikon F zoom lens is high we need sigma or any other make lens at price range betweeen 400-600 usd.

Yes, there are several other lenses similar to the Sigma 24-70mm f/2.8 Nikon F zoom lens that are available for under $600. Here are a few options:

Tamron SP 24-70mm f/2.8 Di VC USD G2: This lens is a great all-around choice for the Chronos 2.1 HD camera. It is sharp, fast, and has excellent image quality. It also has vibration compensation, which is helpful for reducing camera shake when shooting at slower shutter speeds.

Nikon AF-S NIKKOR 24-70mm f/2.8E ED VR: This lens is another great option from Nikon. It is slightly more expensive than the Tamron, but it has a few additional features, such as a fluorine coating on the front element that helps to repel water and dirt.

Sigma 24-105mm f/4 Art: This lens is a good option if you need a bit more reach than the 24-70mm lenses. It is not as fast as the other two lenses, but it is still a sharp and well-built lens.

Yeah true.

Plug the small end of the data cable into the micro-USB port on the camera.
Plug the larger end of the data cable into a USB port on your computer. Depending on your computer operating system, the device appears as either a removable drive or a removable volume on your computer.

Chronos User Discussion / Re: Chronos 1.4 should include camera control and imaging software supported

Thanks for your reply, can you suggest any imaging software whick work well with chronos.

DaVinci Resolve is a common choice of software for viewing & editing footage from the Chronos. It's free, runs on Linux, Mac, Windows, and there's even an iPad version. Blackmagic makes a lot of professional video equipment for it, and typically includes a license for the commercial version with a hardware purchase. https://www.blackmagicdesign.com/products

Final Cut Pro, Premiere Pro, and Sony Vegas Pro are some other popular commercial options.

Kdenlive is another great option- it's free, open source, and runs on Linux, Mac and Windows https://kdenlive.org/en/

Topaz Video AI works well for enhancing Chronos footage, and is especially useful when capturing at higher frame rates which require reduced resolution.

Hello Johndoe,

To connect your camera to your computer with microUSB have a look at section 1.2 of the file "Network-Control-v0.6.5-1_for_Chronos_Cameras.pdf".

You can also control your camera via ethernet, see section 1.1.

You need to install the RNDIS driver on your computer. To do that, follow the instructions in the file "Chronos-RNDIS-Driver-Installation-Guide.pdf"

If you computer has windows 11 installed in it you need to carry out a few extra steps. They are described in the document "Update Port (COM & LPT) for Windows11.pdf"

If you want to download the footage recorded directly to your computer. You need to setup the SMB share, this is outlined in "Chronos-SMB-Share-Setup-Guide.pdf"

We need to know.
Does Chronos 1.4 support below:

Chronos 1.4 high speed camera should include camera control and imaging software supported with Matlab or phyton.

The Chronos 1.4 serves a REST API, a unicast RTSP video stream, and also some CGI scripts for purposes such as retrieving a jpeg of the current live view or video files saved to mounted storage devices. For more information: https://www.krontech.ca/wp-content/uploads/2021/09/Network-Control-v0.6.5-1.pdf

Here is a repository with Matlab & Python scripts for controlling the Chronos 1.4: https://github.com/krontech/chronos-examples
