Final answer:
Postproduction in filmmaking involves editing to shape the narrative, preparing the final print with effects and music, and then bringing the film to the public through marketing and distribution.
Step-by-step explanation:
The three phases of postproduction include editing, preparing the final print, and bringing the film to the public. During postproduction, the director selects the best takes, edits them, and sequences them to shape the storytelling. This editing process is crucial as most of the shots don't make it to the final cut, demonstrating that filmmaking is significantly directed by the vision of the director. Following editing, efforts focus on preparing the final print, integrating music, and adding special effects. Lastly, the film is ready to be unveiled to the audience, which involves marketing strategies and distribution decisions to maximize the film's reach and recoup production costs through various revenue streams like box office, DVD sales, and streaming services.
