Post-Production is the stage after production when the filming is wrapped and the editing of the visual and audio materials begins. Post-Production refers to all of the tasks associated with cutting raw footage, assembling that footage, adding music, dubbing, sound effects, just to name a few.
The Post-Production process is highly collaborative, across a few months to even a year, depending on the size and need of the project.
Post production is the editing of audio and visual materials to create a film. An editor assembles footage shot by shot, adds music, and incorporates other visual and sound effects. These elements are woven together to create a multisensory experience we call a movie.
