摘要
Examples of encoders and video encoding are described that include optimizers and techniques for optimizing syntax elements such as transform coefficients. In some examples, multiple color components of a video signal may be jointly optimized by employing a cost calculation using a combination of distortion and/or rate metrics for multiple color components. In some examples, a color transformation may occur and the optimization may take place in a different color domain than encoding. In some examples, distortion metrics used in the cost calculations performed by optimizers are based on structural similarity index.
