Chronos User Discussion / Macro Video

« on: July 14, 2020, 08:30:27 PM »

I would like to do some macro work with  the monochrome version of the 1.4 (which I should receive any day now).

Will the following lens work?

computar C-Mount 13-130mm Varifocal Lens

Listings say that it is compatible with 1/2" cameras and uses a C-mount.  I assume the 1/2" is the sensor size, but I'm not sure.

Thanks.

Chronos User Discussion / Extracting still images

« on: April 25, 2020, 07:15:52 PM »

I am thinking about purchasing a Chronos camera.  I need super slow motion video, but I also need 1 microsecond still images.  I have emailed Sebastian at Kron and he replied as follows:

"I think the best method of extracting a still image from the camera is by saving the file as cinemaDNG.  This will create a folder on your card containing a number of still adobe dng images that can be opened as a single image in your preferred photo post processing software or as a video sequence in your preferred NLE software by importing the whole folder.

One note when saving cinemaDNG files on the camera, they are much more data heavy (h.264 is up to 60Mbps, cinemaDNG is 1258Mbps) and the save time will be much longer.  I recommend using a SSD if you wish to save cinemaDNG files since the transfer rate is much faster than the SD card."

Has anyone tried this?  How good is the resolution of the image.  Another choice I have is to try  to buy a Vela One flash (as low as 0.5 microsecond), but they are not producing flash units at the moment.  I feel confident that the Vela one will provide a very good image, but I thought I should maybe consider the Kron cameras since I would like to have super slo mo video as well.

Any advice is appreciated.  Thanks.
