1. Nonlinear editing is digital production with the help of computers. Almost all work is completed in the computer, so there is no need for so many external devices. The call of materials is also instantaneous. There is no need to look repeatedly on the tape. It breaks through the limitation of single chronological editing, and can be arranged in various orders. It is fast, simple, and random.
2. Nonlinear editing can be edited many times as long as it is uploaded once, and the signal quality will never decrease, so equipment and manpower are saved and efficiency is improved.
3. Non linear editing requires special editing software and hardware. At present, most TV and film production institutions have adopted non-linear editing systems.
