Jean-François Fortin Tam gave a talk at Libre Graphics Meeting 2009, discussing how usability became a major focus for the Pitivi project, and how design considerations impacted PiTiVi's user-interface, with examples such as the use of subtle gradients in timeline objects, drag and drop importing and direct manipulation, native theme integration, and reducing complexity by carefully evaluating the need (or lack thereof) to impose preference choices onto users. Another talk, focused on the economics of open source video editors, was given by Jean-François at Libre Graphics Meeting 2011.
