Thank you so much for this 
I barely understood half it but I find high speed photography/ videography absolutely fascinating!
Blows my mind how quickly the field seems to be moving (at least from a layman’s perspective) and absolutely can not wait to see current cutting edge tech move in consumer products in the next ~10 years or what not 
Appreciate you and the teams work 
Edit: Forgot to say, I love the cat noises in the background 
Thanks so much!
Interesting that the 1.4 can do a double the framerate (40k) at lower resolutions than the newer cameras (20k).
Probably a trade off when using off-the-shelf ram/ssd, or maybe the 2k/4k camera sensors are slower even at low res. dunno.
Probably orders of magnitude smaller market for ultra high FPS at low res, verses 2k/4k resolution.
Likely higher profits per unit though.
I imagine the really high FPS (100-500kFPS) requires massively striped memory arrays, so quite a different beast.
The newer sensors are much more parallelized, the GSPRINT4521 has an ADC on each pixel column, top and bottom, for 10,240 ADCs operating at ~2MSa/s each. The LUX1300 in the Chronos 1.4 has 16 ADCs at 90MSa/s with multiplexers to select which columns and rows they are reading, so they do better windowing (tradeoff of resolution for speed). What's not shown in the chart is that the new cameras can do those highish (~20kFPS) rates with X widths up to about 1500 pixels, with no speed penalty, due to the column parallel ADCs.
Companies like Phantom have pretty much completely exited the low end market because of us, they only do ultra high frame rate cameras now. That's where I want to get eventually but it is expensive to have custom silicon made...
Those ultra-high frame rate cameras usually use several FPGAs in parallel, using the RAM kind of like a RAID array to handle the higher pixel rates.
