Abstract

This paper presents a software-only MPEG encoder implementation which uses adaptive quantization and scene change detection to enhance the picture quality. Scene change detection is also used to assign picture coding types allowing easy, lossless cutting at scene change positions in a later editing process. Although our current implementation concentrates on MPEG-2, all concepts can also be directly applied to MPEG-4 encoders
