Looks incredible. What recording bit depth were you using here?
P.S. How lucky to see a beautiful red squirrel (although less so to have it scrabbling around in your roof cavity). Good job with the fix.
EDIT: I played around with this this afternoon and was getting pretty reliable recording at 3840x1536 at 14 bits and with the preview left on (overclocking at 240 and all of the hacks on).
The incremental changes by Danne and Bilal (possibly with input from dpjpandone?) over the last couple of years have really boosted the usability of the camera in terms of crashes, recording times at higher res modes and with higher bit depths, and the simply wonderful ultrafast_gray preview, which is perfectly good enough for framing and lets me use the x5 mode for focus on a phone/external monitor. It's a perfect setup! My girlfriend uses the Ursa Mini and A7SIII, and although they're great, she's always lusting after the ML'd 5D3's colours and rendering. :-P
