A novel multi-order-residual (MOR) coding approach is proposed for high-bit-rate video compression in this work. We show that a significant amount of short and medium-range correlations due to the use of a fine quantization parameter cannot be easily removed by the well known motion compensated prediction process in the high-bit- rate coding scenario. Consequently, the video coding performance degrades rapidly as quality increases. To address this issue, we propose a Multi-Order-Residual (MOR) coding scheme that encodes prediction residuals in multiple stages according to their correlation characteristics. Then, we adopt different compensation and coding schemes in different stages. Experimental results are given to show the proposed MOR scheme outperforms H.264/AVC by a significant margin.
