This document presents guidelines for the conduction of subjective experiments for the Quality of Experience (QoE) assessment of perceptual video quality dimensions. In addition to scores for the overall video quality, the methodology yields scores for five perceptual dimensions. Each perceptual dimension scores are based on ratings of the amount of degradation present in one system/test con-dition. The method is designed to be used with naïve subjects. The dimension scores can be used to provide diagnostic information on what may cause the degradation. The perceptual dimensions are described in this document as well as the method to conduct a sub-jective experiment. Furthermore, we give information about possible test environment and setup, participant instructions, and test material
