in-camera editing

In-camera editing refers to filming in the exact order required for the final product, thereby eliminating the post-production editing stage. A fast, albeit unprofessional way to produce a film, often employed by student or amateur filmmakers; requires advanced planning to tell the desired story in order. Also known as "in-camera effects," such as double-exposures, split-screen shots, rear-screen and front-projection process shots, etc.
