By default the encoder uses a single Rice parameter for the subframe's entire residual. With this option, the residual is iteratively partitioned into 2^min# .. 2^max# pieces, each with its own Rice parameter. Higher values of max# yield diminishing returns. The most bang for the buck is usually with <B><TT>-r 2,2</TT></B> (more for higher block sizes). This usually shaves off about 1.5%. The technique tends to peak out about when blocksize/(2^n)=128. Use <B><TT>-r 0,16</TT></B> to force the highest degree of optimization.

Set the Rice parameter search distance. Defaults to 0. The residual coder will search for the best Rice parameter +/- this number for each residual partition. This option is expensive (run time for -R n will typically be (2n)*30% over that of -R 0) and doesn't give much of a gain. As a matter of fact, none of the -0..-8 options currently use it since -R > 1 is not consistently better like it should be.
