Hi Rivai,
There is nothing published by Apple, neither inside FC, that leads to think that 10b RGB rendering is possible.
In his post, the guy of CineForm, basically says that they are unable. They have to convert and render in YUV.
Last year, after similar discussion, I asked Graeme Nattress about. Also Owen Smithyman of BitJazz (Sheer codec).
Nobody even considered the possibility of FC rendering in 10b.
Owen proved that was possible to cut and export without rendering, keeping the 10b RGB.
Personally, I don't understand any piece of software hiding what should be his best highlight.
Cheers,
Rafael
PS: 444 is not a color space but a "mapping/sampling pattern" (422, 420, 411).
Tolking about 444RGB makes no much sense as long as there are no 422/420/411 RGB formats.
Down sampling in RGB is not possible.
