Which codec would you select? C300 Mark ii/Shogun Connect

[Mike Falevits]

Which codec do you prefer and why?

Canon C300 Mark ii internal vs external codecs:

Internal

2K DCI 12 Bit 4:4:4 Intra – XF-AVC Long GOP H.264

Or

External

4K DCI 10 Bit ProRes RAW

(External via SDI to Atomos Shogun Connect)

 

It seems like the 12 Bit 444 color profile would have a greater pixel quality, but its compressed format might compromise flexibility in post. So is it worth compromising the bit depth for 10 Bit RAW in this case?

Thank you.
