August 25, me:
Just stumbled upon something interesting in the firmware. Not sure if nikfreak or anyone else tried that.
call("lv_daf_mode", 1); // "FACTORY:AB_OUT_LEFT" call("lv_daf_mode", 2); // "FACTORY:AB_OUT_RIGHT" call("lv_daf_mode", 0); // guess: default, both "channels"
I'd like to see some DNGs from LiveView (plain 1080p) after calling the above functions, without camera movement between the test shots if possible.

Two years ago I've started to look into Dual Pixel RAW files from 5D Mark IV. Beware: unfinished experiments.
One of my goals was (and still is) to see how far out-of-focus images can be recovered or refocused, with my own algorithms. That wasn't exactly easy for an image processing n00b like me, but got some promising results on synthetic data (look at , ,  and  in the above link). The other goal - if results are worth the effort, why not expand the concept to dual pixel raw video?
Oh well, so many interesting things to research, so little time...
Yes, the above DNGs were from LiveView, i.e. dual pixel raw video. Just 2 frames for now - Canon engineers called them "FACTORY:AB_OUT_LEFT" and "FACTORY:AB_OUT_RIGHT", whatever that means.
