Abstract
A video coding system is provided including generating a motion vector for a macro block in a picture, the motion vectors indicative of displacement of an object in the macro block; grouping a cluster of the motion vectors; and adjusting a dynamic quantization parameter modulation of a subsequent picture based on the grouping for displaying the displacement of the object in the subsequent picture.
