Several studies on very low bit rate video coding have been reported. One of the major goals of the studies is to improve the coding performance, which gives better subjective and objective quality than conventional coding methods at the same bit rate. As the shape and structure of an object in a picture are arbitrary, the performance of traditional coding with block-based motion compensation (MC) is not satisfactory. We present advanced MC schemes for very low bit-rate video coding. The major features of the proposed MC are block-partitioning prediction and the utilization of two time-differential reference frames. This coding scheme improves the image quality around the objects' boundaries and consequently reduces prediction errors. It also works well in the case of object occlusions. The combination of the proposed MC and discrete cosine transformation (DCT) shows a better performance in several test sequences than full-spec H.263
