Why not go for the Chronos 4K12?

What's the resolution to get to around 40,000 fps with the 2.1?
Here are a few settings the Chronos 2.1 can achieve near 40,000fps
HRes VRes FPS 1920 20 40496.8 1280 32 37745.3 1024 38 39787.8 800 52 39745.6
Lower bit depth data must be physically recordable by the cameras' sensors. In the event that the sensors are only meant for 12-bit capture, it could be challenging to achieve lower bit depths using firmware alone.
yes the answer you have writes is perfectly fine
Hi
Is the square sensor of the Q12 made for all the 9-16 format requests that we get all the time?

I use the 7Artisans f/0.95 35mm MFT lens. I usually film at f/0.95 or f/1.2.
I have the color model of the Chronos 2.1 and the fastest framerate I was able to configure it to calibrate & record was 114,504fps at 800x8 resolution, which would be 3,816.8x slow motion with a 30fps playback. These numbers seem to deviate from the specs on the Luxima website. For example, the maximum framerate at 1920x8 resolution reported by the camera is 73242.2fps, however the Luxima website states 125,000 FPS @ 1920 x 8
The configuration process is not very hard or time consuming. Simply follow the steps @sanjay described earlier in this thread, except for Step #6, use the following instead:
nano pychronos/pychronos/sensors/lux2100.py
change MIN_VRES = 96 to MIN_VRES = 8 on line 32
change numRows = 64 to numRows = 16 on line 652
save and exit the file with Ctrl + O then Ctrl + X
Furthermore, it may be of interest to modify the /var/camera/resolutions file as @mklinger mentioned. For both the 2.1 and 1.4, that's used for populating the presets drow-down menu and the list of resolutions which the "Black Calibrate All Resolutions" button triggers calibration data to be created for
