https://community.usa.canon.com/t5/Professional-Video/Concerning-PRE-RECORDING-a-question-for-Canon-developers/m-p/359310#M1789 <P>Dear Canon,</P><P>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.</P><P>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 &amp; 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.</P><P>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 &amp; fast motion or RAW.&nbsp;</P><P>How are the pre-record restrictions brought about? Could the C300 Mark III potentially increase its abilities here with a firmware update?&nbsp;</P> Mon, 03 Jan 2022 03:04:24 GMT bjorneo 2022-01-03T03:04:24Z https://community.usa.canon.com/t5/Professional-Video/Concerning-PRE-RECORDING-a-question-for-Canon-developers/m-p/359310#M1789 <P>Dear Canon,</P><P>As someone working in wildlife I'm a big fan of the "pre-recording" function, also known as pre-roll on other cameras.
