How to do non-linear video editing?

Nonlinear editing is for linear editing. In traditional TV program production, TV editing is done on an editing machine. The editing machine usually consists of a playback camera and a videotape recorder. The editor selects a suitable piece of footage through the playback camera and records it on the tape in the videotape recorder, then looks for the next shot and proceeds with the recording work, and so on and so forth until all the suitable footage is recorded in the entire sequence according to the program requirements.

Because the tape recording screen is sequential, can not be inserted in the existing screen between a shot, can not delete a shot, unless the screen after this all re-recorded again, this editing is called linear editing, which brings a lot of limitations to the editors, editing efficiency is very low.

Nonlinear editing is the application of computer graphics technology, in the computer on a variety of original material for a variety of editing operations, and the final results will be output to the computer hard disk, tape, video tape and other recording equipment on this series of complete process. As the original material is digitized and stored on the computer hard disk, the location of the information stored is parallel and parallel, with the original material input to the computer when the sequence has nothing to do. In this way, we can be stored on the hard disk of the digitized audio and video material for arbitrary combinations, and can be easily modified, the advantages of non-linear editing that is embodied in this, its efficiency is very high, you now have to do is how to create your work, how to play your imagination, and no longer need to be subjected to the limitations of linear editing.
