1. A method of adjusting utilization of prediction error computational resources of a video processing system during processing of video data, wherein the video data includes multiple sets of image data, the method comprising: processing the set of image data to generate a prediction error between a first set of image data and a second set of image data; evaluating the prediction error relative to a measure of motion represented in the first set of image data; and processing the image data to reduce a prediction error if one or more conditions of the video processing system indicate a desirability of reducing the prediction error.
