H.264/MPEG-4 AVC has become widely used in various applications and services because of its high coding efficiency. With the spread of H.264/MPEG-4 AVC contents, it has been strongly required to edit the H.264/MPEG-4 AVC coded contents with less computational complexity since the compression of H.264/MPEG-4 AVC requires far more processing power than other existing formats such as MPEG-4, MPEG-2. In this paper, we propose a fast frame-accurate editing method for H.264/MPEG-4 AVC contents. In the proposed method, we employed "adaptive bit allocation and GOP-length modification" and "Re-quantization scheme with drift noise management" The proposed editing method can realize frame-accurate cut and splice editing regardless of picture coding types I, P, and B. In the experiment, we could also confirm the effectiveness of the proposed method in terms of processing power and the picture quality of the edited contents when compared with conventional editing
