Claim:
1. A tangible computer-readable media storing computer-executable instructions for causing a computer system, when programmed thereby, to perform video processing comprising: packing sample values of an input picture organized according to an input picture format into a first coded picture organized according to a first coded picture format and a second coded picture organized according to a second coded picture format, the first coded picture containing sample values for a low chroma resolution version of the input picture, and the second coded picture containing sample values for high chroma resolution details of the input picture; separately encoding the first and second coded pictures to produce encoded data, including selecting one or more regions in which corresponding sample values for high chroma resolution details of the input picture are encoded as part of the second coded picture; outputting the encoded data, wherein the encoded data is output as a sequence of coded pictures, and wherein the first coded picture is encoded as part of a first sub-sequence of the sequence and the second coded picture is encoded as part of a second sub-sequence of the sequence, the second sub-sequence being different than the first sub-sequence; and outputting region data that identifies the one or more regions in which the corresponding sample values for high chroma resolution details of the input picture are encoded as part of the second coded picture.
