Post-production is the final stage in film and program-making where footage is cut, music, sound, and commentary are mixed, and visual effects are added. It is the phase of the filmmaking process where the footage shot during principal photography is assembled into a cohesive narrative and other aspects of the film are put into place and polished, including the dialogue, score, sound effects, and visual effects. The post-production process involves a slew of professionals, including editors, sound designers, foley artists, colorists, and more. The process of post-production is highly collaborative and can take several months to complete, depending on the size and need of the project. The post-production phase of creating a film usually takes longer than the actual shooting of the film. The post-production process is critical to the success of a movie, and every part of the filmmaking process is essential to the success of a movie, and post-production is no exception.
