Abstract : In this work we investigate the performance of the H.264/AVC video coding standard for low bit rate mobile multimedia messaging services (MMS). We focus on the appropriate selection of the quantization parameter and the temporal resolution. For this purpose, a psycho-visual experiment has been designed. It is revealed that only limited set of parameter values is necessary to span almost the entire range of quality levels. In general quantization parameters of 34 and frame rates of 10 Hz are sufficient to provide good quality. Sports sequences ask for slightly higher frame rate, 15 Hz is sufficient. To provide suffi-cient quality, quantization parameters below 40 and frame rates below 5 Hz should definitely not be used.
