+is done transparently on the GPU. Input and output is 8-bit Y'CbCr by default,
+but be aware that 8-bit Y'CbCr, however common, cannot capture the full color
+fidelity of 8-bit RGB (not to mention 10-bit RGB). If you have spare GPU power,
+you can enable 10-bit Y'CbCr input and output with --10-bit-input and
+--10-bit-output, respectively, although you should be aware that client
+support for 10-bit H.264 is very limited. Also, Quick Sync Video does not
+support 10-bit H.264 encoding, so in this case, the digital intermediate needs
+to be encoded in software.
