The lowend Alexa shoots 12 bit Prores 444 on the SxS cards in LogC.  Though
for whatever reason tv shows always seem to shoot it in 422 mode.  I'm not
sure if it's out of habit or they are trying to get more time on each SxS
card?  I always ask the vfx house why and they shrug their shoulders and
say they couldn't sway production to do it differently.  I would just try
to push production to shot prores 444 instead of getting another device.
