ABSTRACT
Today postproduction video editing is done with the use of a digital nonlinear editing (NLE) system. These systems provide random access to footage; the ability to make changes with ease to edited sequences at any point in the program time line; and the ability to easily integrate graphics, sound and special effects. Nonlinear editing systems provide random access to source footage. Source footage is imported into the computer and stored on the computer’s hard disk drives. Digital nonlinear editing is nondestructive of the original field footage. The time line is a graphical linear representation of the program. Clips are digital files of the source material that is to be edited. Clips are trimmed in an editing window. Rendering is a process through which the computer changes transitions, special effects, and graphics from computer effects to video effects. File management is a big issue in nonlinear editing.
