This paper describes an experiment designed to ultimately derive a set of meaningful perceptual factors for the classi cation of audiovisual media content. Whereas such factors or attributes are available for the classi cation of video only content, they are missing for audiovisual content. Based on the suggestions made by Woszczyk et al. in their 1995 AES Convention paper, we have taken a closer look at these factors in a combined set of experiments, one consisting in a quality trade-o decision, and one consisting in a relevance sorting task with subsequent rating of attributes. The hypothesized correlation between the most relevant perceptual factors and the preferred quality trade-o between modalities in audiovisual media content could be established for some type of media content, but not for all, and is weaker than expected.
