Landscape-Portrait OGG Format

Just looking at the next phase for Landscape-Portrait. I want to create a Wikipedia page for he project, in addition upload the content to Wikipedia or Wikicommons. Either will require me to reformat the video portraits using the ogg codec. I guess I am concerned about the type of license also, 'fair use' seems appropriate but this would exclude the commons, where content is made available copyright free. There is also the question of the participants rights, and thoughts of how this content will be used.
