| For 2D images, '''non-destructive editing''' is a form of editing signals where the original content is not modified in the course of editing - instead the edits themselves are edited. | |||
| A pointer-based playlist — effectively an ] — is used to keep track of edits. Each time the edited audio or video is played back or accessed, it is reconstructed from the original source and the EDL. Although this process is more computationally intensive than rendering each edit, changing the edits themselves can be almost instantaneous, and it prevents further ] as the audio or video is edited. | |||
| When ] was first developed in 1956 by ], the only way to edit was to physically cut the tape with a razor blade and splice segments together. While the footage excised in this process was not technically "destroyed", continuity was lost and the footage was generally discarded. | |||
| In 1963 with the introduction of the ] Editec, video tape could be edited electronically with a process known as ] by selectively copying (or dubbing) the original footage to another tape called a "master". The original recordings are not destroyed or altered in this process. | |||
| ], originally developed in 1971 by ] and now the most prevalent form of editing video and film, is also non-destructive: Un-edited original footage is digitized into electronic files stored digitally on a computerized disk-based system. The edited end-product (often referred to as a "sequence" or "playlist") is simply a series of digital files played back out of the editing computer. In this case, neither the original footage nor the digitized source files are destroyed in the editing process. | |||
