MPEG-4 iS one of the most important and influential international multimedia data compression encorders．To meet the demands of a video encoding for the large computation load and strong computing power，a optimized encoding method of MPEG-4 based on TMS320C6416T is presented． According to the characteristics of C64x DSP，severaI kinds of methods for software optimization are proposed，which includes allocating memories in reason，setting two buffers in a memory based on the characteristic of EDMA．realizing a core code by linear assembly language and optimizing C language for whole programs．Experimental results show that the encoder CaR realize real—time encoding for rid— eo images with 768 pixel X 576 pixel，in 25 frame／s。
