Participatory video (PV) is a form of participatory media in which a group or community creates their own film. The idea behind this is that making a video is easy and accessible, and is a great way of bringing people together to explore issues, voice concerns or simply to be creative and tell stories[citation needed]. It is therefore primarily about process, though high quality and accessible films (products) can be created using these methods if that is a desired outcome. This process can be very empowering, enabling a group or community to take their own action to solve their own problems, and also to communicate their needs and ideas to decision-makers and/or other groups and communities. As such, PV can be a highly effective tool to engage and mobilise marginalised people, and to help them to implement their own forms of sustainable development based on local needs.
