According to 4k video
1. Similar steps has been seen by 5d MK iV. No idea how it works now with the latest firmware

2. Crop OK but what about dual pixel AF
PS I understand the technical issue to have 24MP 2x3 to be used in 16:9 mode at 4k == 8.3MPixels - seems logical that you need crop sqrt(24/8.3) = 1.6. But this is quick and dirty solution
I have no idea how other manufacturer cope with the video crop issue. I know that it works fine with modern 2..15MP smarphone sensors
