CineFX Overview Slides (.pdf) (7543 KB)
的第14/15頁有提到
High Precision Color Details
16-bit floating point format
The same exact format that Pixar & ILM use for films
So-called s10e5 representation
1 bit sign
10 bit mantissa
5 bit exponent, -15 bias
Otherwise IEEE 754 floating-point semantics
More range than signed shorts
Half the space & bandwidth of a 32-bit floating-point value
32-bit Floating Point format: IEEE s23e8
這是不是代表NV3X好像也可以Run HDR.
