This article concentrates on a quality assessment for H.264 coded low-rate and low-resolution video sequences which are in particular of interest for mobile communication. The choice of appropriate setup for tests is discussed. The focus is given on the influence of the sequence character (spatial and temporal information). The data set is compared to various known video quality metrics. It is shown on the obtained data set, that it is not possible to separate the dynamic and static parameters without considering the character of the sequence and thus to create a universal metric. KEY WORDS H.264, subjective perceptual video quality, spacial information, temporal information.
