Post-production is the third and final step in film creation, and it refers to the tasks that must be completed or executed after the filming or shooting ends. The three main phases of post-production are compositing, sound editing and video editing.
Compositing:
The compositing department brings together all of the 3D elements produced by the previous departments in the pipeline to create the final rendered image ready for animation. Compositors take rendered images from lighters to initially comp together their dailies.
General compositing tasks include rendering the different passes delivered by a lighting department to form the final shot, paint fixes and rotoscoping.
Sound editing:
This department is responsible for selecting and assembling the sound recordings in preparation for the final sound mix, ensuring lip synv and adding all of the sound effects required for the final animation.
Video editing:
Video editing is the process of manipulating and rearranging shots to create a seamless final product. Editing is a crucial step in making sure the video flows in a way which achieves the initial goal. Other tasks include titling and adding any effects to the final video and text.
