Post-production is part of the process of filmmaking, video production, and photography. Post-production includes all stages of production occurring after shooting or recording individual program segments.
Post-production is many different processes grouped under one name. These typically include:
- Video editing the picture of a television program using an edit decision list (EDL)
- Writing, (re)recording, and editing the soundtrack.
- Adding visual special effects - mainly computer-generated imagery (CGI) and digital copy from which release prints will be made (although this may be made obsolete by digital-cinema technologies).
- Sound design, sound effects, ADR, foley, and music, culminating in a process known as sound re-recording or mixing with professional audio equipment.
- Transfer of colour motion picture film to video or DPX with a telecine and color grading (correction) in a color suite.
The post-production phase of creating a film usually takes longer than the actual shooting of the film and can take several months to complete because it includes the complete editing, colour correction, and the addition of music and sound. The process of editing a movie is also seen as the second directing because through post-production it is possible to change the intention of the movie. Furthermore, through the use of color grading tools and the addition of music and sound, the atmosphere of the movie can be heavily influenced. For instance, a blue-tinted movie is associated with a cold atmosphere and the choice of music and sound increases the effect of the shown scenes to the audience.
