Video for Change refers to the practice of using video to activate social change and ongoing work in this field seeks to define and establish ethical principles that can inform and direct this process and practice. This paper reports on an ongoing action research project with a network of 10 Video for Change organisations. The study investigated what makes Video for Change a unique media-making and social change field and it examined the kind of ethical practices most valued by Video for Change practitioners. The purpose of the study was to inform an ethical impact framework and toolkit to support practitioners to both design for and evaluate their social impact. This working paper reports on the study's key findings, while also highlighting many of the challenges of designing and measuring the social impact of video initiatives across diverse contexts.
