Postproduction is part of the film making process, video production, and photography. Post-production covers all stages of production that occur after taking a picture or recording individual program segments.
Traditional (analog) postproduction has been largely superseded by video editing software operating on non-linear editing systems (NLE).
Video Post-production
Process
Post-production many different processes are grouped under one name. This usually includes:
- Video editing a television program image using an edit decision list (EDL)
- Write, (re) record, and edit the soundtrack.
- Add visual special effects - especially computer-generated imagery (CGI) and digital copies from which release prints will be created (though this may be obsolete by digital-cinema technology).
- Sound design, sound effects, ADR, foley, and music, culminate in a process known as sound recording or mixing with professional audio equipment.
- Transfer a color image film to a video or DPX with telecine and color grading in a series of colors.
The post-production phase of filmmaking usually takes longer than actual film shooting and can take several months to complete as it includes full editing, color correction, and the addition of music and sound. The process of film editing is also seen as the second directing because through post-production it is possible to change the purpose of the film. Furthermore, through the use of color scoring tools and the addition of music and sound, the mood of the film can be greatly influenced. For example, a blue film is associated with a cool atmosphere and the choice of music and sound enhances the effect of the scene that is shown to the audience.
Post-production is called "dying industry" by Phil Izzo. Exclusive services offered by top-class post-production facilities have been eroded by video editing software operating on non-linear (NLE) editing systems. Thus, traditional (analog) post-production services are being surpassed by digital, leading to sales of more than $ 6 billion per year.

Television
On television, the post-production phase includes: editing, video editing, voice editing, animation and visual effects, viewing and starting the delivery process. It is vital that post-production executes and supervises preparations until the final product is completely ready.
Photography
Professional post-producers typically apply various image editing operations to raw image formats provided by photographers or image banks. There are various proprietary and free and open-source software, running on the various operating systems available to do this work.
The first post-production stage usually requires the loading of raw images into post-production software. If there is more than one image, and they are included in a set, ideally post-producers try to match the image before loading it. After that, if necessary, the next step is to cut the objects in the drawing with the Pen Tool for a perfect cut and clean. The next stage is to clean the image using tools such as healers, cloning tools, and patch tools.
The next stage depends on what the client ordered. If it is a photo montage, post producers will usually start collecting different images into the final document, and begin integrating the image with the background.
In advertising, it usually requires assembling multiple images together in a photo composition.
Types of work usually done:
- An ad that needs one background (as one or more images to assemble) and one or more models. (Usually, the most time consuming because many times this is a picture bank image that does not have much quality, and they all have different light and color because they are not controlled by only one photographer in one set location)
- Product photography usually requires multiple images of the same object with different lights, and is coupled together, to control light and unwanted reflections, or to assemble parts that would be difficult to obtain in a single portrait, such as beer beers for beer advertisements. (Sometimes to combine one picture of a beer glass takes 4 or 5 pictures: one for base, one for beer, one for label, one for foam, and one or more to splash beer if desired)/li>
- Fashion photography that usually requires very heavy post-production for editorial or advertising.
Music
Techniques used in postproduction of music include comping (compiling the best parts of multiple take one take superior), timing and pitch correction (possibly through quantization of beats), and adding effects. This process is usually referred to as mixing and can also involve equalization and adjusting the level of each individual track to provide an optimal sound experience. Contrary to the name, postproduction may occur at any time during the recording and production process and non-linear and nonveridic.
