Post-production occurs in the making of audio recordings, films/movies,and videos. It is the general term for all stages of production occurring after the actual recording and ending with the completed record, film or video. Post-production is in fact many different processes grouped under one name. These typically include:

• Editing the picture.
• Editing the soundtrack.
• Writing and recording the soundtrack music.
• Adding visual special effects - mainly computer generated imagery (CGI) and digital compositing, formerly also optical effects.
• Adding audio sound effects - like ADR, Foley, sound design and sound designersactions.
• Color grading, and digital editing of the final master copy from which release prints will be made
• Typically, the post-production phase of creating a film takes longer than the actual shooting of the film, and can take several months to complete.
• Other film production stages include (very broadly) - financing, pre-production, writing the screenplay, rewriting the screenplay (repeat), and the actual shooting.
