1. A method of encoding video comprising:

  • encoding base layer video to produce at least part of a base layer bitstream;

    determining chroma high-pass residual layer video and sample depth residual layer video from input video and a reconstructed version of the base layer video;

    remapping samples of the sample depth residual layer video from a first range to a second range;

    encoding the chroma high-pass residual layer video to produce at least part of a chroma enhancement layer bitstream;

    encoding the remapped samples of the sample depth residual layer video to produce at least part of a sample depth enhancement layer bitstream; and

    outputting the at least part of the base layer bitstream, the at least part of the chroma enhancement layer bitstream, and the at least part of the sample depth enhancement layer bitstream.
