Hi Roman and Timo,
Timo is right. As a general rule, hybrid video coding standards allow encoders
to take advantage of encoding
a 8-bit input as 10-bit due to the interpolation filters (inter and intra) and
transform coding at 10-bit depth.
This can generate a better prediction and reduced bandi
Thanks for the explanation, Timo!
I was hoping that 8>10 bit up-conversion which happens in the driver may
bring some goodness like SDR > HDR conversion, recently presented by NV. Or
some other algo which is easier to keep proprietary.
Otherwise, although it is convenient in some use cases, it doe
