Non-Destructive Editing (Paperback)

High Quality Content by WIKIPEDIA articles! 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 edit decision list - 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 generation loss as the audio or video is edited.
