As someone working in wildlife I'm a big fan of the "pre-recording" function, also known as pre-roll on other cameras. This is where RED dominates most cameras as it gives you, I don't know, is it up to 30 seconds pre-record? In any case it's more than 20 seconds, which is extremely useful and a big reason to opt for RED on certain productions.
The Canon C300 Mark III is a beautiful camera, but it offers only approx. 2 seconds pre-recording. It doesn't work in conjunction with slow & fast motion, and the C300 Mark III pre-recording doesn't work with RAW. For these reasons, the C300 Mark III pre-record is somewhat useless in my case, which is a pity because its potential is so powerful.
I don't understand the technical constraints that restrict pre-recording to only 2 seconds and only three set frame rates (23.98p, 29.97p, 59.94p), and why it doesn't work with slow & fast motion or RAW.
How are the pre-record restrictions brought about? Could the C300 Mark III potentially increase its abilities here with a firmware update?
My guess is RAM. With the 410 Mbps codec, 30 seconds would require 1.5 GB of memory. More for higher frame rates and definitely more for RAW.
