Linear
Editing is a process of selecting, arranging and modifying images and sound in
a pre-determined, ordered sequence – from start to finish. Linear editing is
most commonly used when working with videotape. Unlike film, videotape cannot
be physically cut into pieces to be spliced together to create a new order.
Instead, the editor must dub or record each desired video clip onto a master
tape.For example, let’s say an editor has three source
tapes; A, B and C and he decided that he would use tape C first, B second and A
third. He would then start by cutting up tape C to the beginning of the clip he
wants to use, then as he plays tape C, it would also be simultaneously
recording the clip onto a master tape. When the desired clip from tape C is
done, the recording is stopped. Then the whole process is repeated with tapes B
and A.
There
was alternative starting to emerge - almost a rejection of the strict time code
rules of linear editing and going back to the freedom of cutting actual film -
a system that would eventually be called Non-Linear editing. Non linear editing
was nondestructive. You could assemble a cut in whatever order you wanted and
go back and make changes without disturbing the rest of the assembly. There was
no generation loss that you had with linear editing that required you to copy
from one tape to another. It was a much more natural way of editing.
Nonlinear editing differs from linear editing in several ways.
First, video from the sources is recorded to the editing computer’s hard drive or RAID array prior to the edit session.
Transitions can be placed between the segments. Also, most of the video editing programs have some sort of CG or character generator feature built in for lower-thirds or titles.
The work-in-progress can be viewed at any time during the edit in real time. Once the edit is complete, it is finally laid to video.
Non-linear video editing removes the need to lay down video in real time. It also allows the individual doing the editing to make changes at any point without affecting the rest of the edit.
