believe in build 3 Months I had installed on my D5 It was possible I remember when the DUAL ISO menu was enabled It was filming a video in RAW Patterned lines Interlaced As I shoot stills in DUAL ISO
(I take a lot of photos at ISO DUAL I remember when I was filming a video in RAW I turn off IN menu DUAL ISO Because I had the pattern lines)
But in the last build
When the DUAL ISO menu is on
It does nothing in video
