YouTube provides a universe of possibilities in supporting your research paper. Most notably this will be in the form of film clips and interviews.
The clips loaded on to YouTube are the documentary's or feature films most poignant moments. These scenes should be analyzed for their relevancy to your thesis and argument. Take the selected scenes from either your film viewing experience or YouTube and think hard as to where they would fit into the organization of your paper. Each scene should create a momentum driving transition in your paper's organization and argument.
