1. An apparatus for decoding video, comprising:
means for decoding, with a residue decoder, encoded video data to determine transformed residual sample data, wherein the decoding with the residue decoder includes
identifying, from a syntax element of the encoded video data, coefficients of a selected inverse color transform, and
performing an inverse transform and an inverse quantization to produce the transformed residual sample data;
means for performing the selected inverse color transform using the coefficients on the transformed residual sample data to produce inverse transformed residual sample data;
means for generating motion predicted image data using motion prediction; and
means for combining the inverse transformed residual sample data with the motion predicted image data to generate restored image data for the current image area of an output video.
