Post-production is part of the process of filmmaking, video production, and photography. It occurs in the making of motion pictures, television programs, radio programs, advertising, audio recordings, photography, and digital art. Post-production includes all stages of production occurring after shooting or recording individual program segments.

Post-production phase is when the audio and visual materials are cut together to create a film, and happens after principal shooting is complete. An editor assembles footage shot-by-shot, adds music (either original or licensed), and incorporates other sound and visual effects. Some elements of filming, like pick-up shots, voiceover, or ADR may be included in the post-production phase. These elements are woven together to create a multi-sensory experience we call a movie.
