Catarina Carneiro de Sousa aka CapCat Ragu published an article about the use of machinima to document art projects:
This paper intends to reflect on the use of machinima as a form of documentation of artistic projects undertaken in collaborative virtual environments online. Artistic projects in user generated virtual environment have an ephemeral and volatile nature. In many of the circumstances it is not possible for the authors to archive the work in its entirety, thereby using registration forms to document their own work or that of others. The capture of moving images on the screen becomes a way of trying to register the spatiality and interactivity of these environments. However, this registration process can never be neutral and reflects the personal and creative vision of its author (whether or not the creator of the work documented). Can the creative nature of recording and editing machinima make these records a new work?
