Claim Text:
1. A method of video encoding, comprising: generating at least one spatial variance measure across groups of pixels of at least one frame of a stream of frames; encoding said one frame variably, in dependence on said spatial variance measure; generating a prediction of values of a one of said groups of pixels using a prediction mode selected from one of Inter-mode prediction and Intra-mode prediction; encoding said one group of pixels at least partially in dependence on said prediction, wherein said selected prediction mode is at least partially dependent on a spatial variance measure for said one group of pixels; generating a bit budget for said one of said groups of pixels based on said spatial variance measure; and loading said one of said groups of pixels and a plurality of previous groups of pixels into a Network Abstraction Layer Unit (NALU) until a sum of respective bit budgets for: said one of said groups of pixels, said plurality of previous groups of pixels, and a subsequent group of pixels is greater than a number of bits available in a payload of said NALU.
