On my D5600 I couldn't use the ISO property (grayed out) . The data type for ExposureIndex is uint16 not uint32. But the MovieExposureIndex DOES use uint32. I've confirmed that this change works on D5600 and have confirmed with the SDK that it is correct for D600 but have not tested on other cameras.
