This paper reports about a new domain-specific variability modeling language, called VM, resulting from the close collaboration with industrial partners in the video domain. We expose the requirements and advanced variability constructs required to characterize and realize variations of physical properties of a video (such as objects' speed or scene illumination). The results of our experiments and industrial experience show that VM is effective to model complex variability information and can be exploited to synthesize video variants. We concluded that basic variability mechanisms are useful but not enough, attributes and multi-features are of prior importance, and meta-information is relevant for efficient variability analysis. In addition, we questioned the existence of one-size-fits-all variability modeling solution applicable in any industry. Yet, some common needs for modeling variability are becoming apparent such as support for attributes and multi-features.
