摘要：Video transcoding is a process of converting one form of video into another form. It provides fine and dynamic adjustment in the bit rate of video bit stream in the compressed domain without imposing additional function in the decoder. In that, H.264 is a successful video coding technique to address a large range of applications, bit rates resolutions qualities and services. Down sampling is special technique used in H.264 to reduce sampling rate of a signal and spatial resolution filter is an optical devices which uses the principles of Fourier options to alter the structure of a coherent light or other electromagnetic radiation, it also one of the technique of spatial domain. Intra-frame is used in video coding (compression) in the video sequence and the H.264/AVC intra-frame decoding and encoding contain a set of computation-intensive coding tools forming a loop in which the data are strongly dependant. We found that in H.264 quality of motion picture degrades so we propose Spatial Resolution Filter to improve the quality. Our experimental result shows that the high computation time saving can be achieved with only negligible quality degradation.
