YCbCr is much bigger than RGB even if it is full RGB to full YCbCr (you are using limited though, right? Only DV profile 5 is full range). 8 bit RGB require 10 bit YCbCr to preserve it and 10 bit RGB require 12 bit.

Some dumb example, even if you are using YCbCr BT.709 limited values 139, 151, 24 that is RGB -21, 182, 181. That is out-of-gamut for BT.709, obviously since negative RGB. Okay? But all 3 components are inside 16-235, 16-240, 16-240 range for Y, Cb, Cr.
