Rough Cut Lab refers to a specialized workshop or program offered by various film festivals and organizations to support filmmakers, particularly documentary filmmakers, during the crucial rough-cut stage of their projects. These labs typically provide selected film teams with access to international industry mentors, editors, and experts for feedback and guidance on storytelling, editing, marketing, and festival strategies. Notable examples include the Antenna Rough Cut Lab, organized by the Antenna Documentary Film Festival in Australia, and Rough Cut Lab Africa (RCLA), a pan-African initiative associated with the Encounters South African International Documentary Festival. Visions du Réel also hosts a VdR–Rough Cut Lab, an intimate workshop designed for feature-length projects seeking specific advice on their most up-to-date rough cuts.
