Hi everyone, I just took delivery of my Chronos 2.1 today and am excited to start making videos!
I wanted to better understand the relationship between the various resolutions and max frame rate. As you probably know, as you window-down the resolution, you have access to faster speeds. In general, the camera does 2.1 Gpix/sec, but in reality, I've found it can range from 2.28 Gpix/sec to 1.48 Gpix/sec.
I knew that there was overhead wrt to frame generation and different horizontal resolutions, but what was somewhat a surprise to me is that the camera really only has 4 ideal horizontal resolutions: 1920, 1472, 1152, and 832. Anything different than those, it'd be the same as cropping in post.
For example, the absolute highest pixel rate for the camera is 1472x1080 @ 1434.28 fps. If you shoot at 1184x1080 you can still only go 1434.28 fps, but when you make the tiny jump to 1152x1080 you make a big speed bump to 1808.06 fps.
It looks like there are no surprises with decreasing vertical resolution as the size correlates well to framerate in a smooth fashion.
Check out the attached image for the full chart. The first one shows the resolution and max frame-rate and other one shows pixel rate color-coded from green to red from fastest to slowest.
I thought it was interesting and might help others focus on ideal resolutions to get the most from the camera.
