Non-linear editing is a form of offline editing for audio, video, and image editing. In offline editing, the original content is not modified in the course of editing. In non-linear editing, edits are specified and modified by specialized software. A pointer-based playlist, effectively an edit decision list (EDL), for video and audio, or a directed acyclic graph for still images, is used to keep track of edits. Each time the edited audio, video, or image is rendered, played back, or accessed, it is reconstructed from the original source and the specified editing steps. Although this process is more computationally intensive than directly modifying the original content, changing the edits themselves can be almost instantaneous, and it prevents further generation loss as the audio, video, or image is edited.
The NewTek Video Toaster is a combination of hardware and software for the editing and production of NTSC standard-definition video.

QFX is an image editing computer program developed by Ron Scott, a Texan photographer and software engineer. The first version was released in 1990. At the time of its release, QFX was one of the most feature-rich image editing applications available on the PC platform. It was the software of choice for digital artists and image postproduction studios in the times when 1024x768 truecolor graphics were a luxury, far before Photoshop could have been considered a serious professional tool. Its clean interface and clever workflow helped build a devoted user base, some of whom continue using it, despite QFXs being long ago eclipsed in features and users by Photoshop.
Motion graphics are pieces of animation or digital footage that create the illusion of motion or rotation, and are usually combined with audio for use in multimedia projects. Motion graphics are usually displayed via electronic media technology, but may also be displayed via manual powered technology. The term distinguishes static graphics from those with a transforming appearance over time, without over-specifying the form. While any form of experimental or abstract animation can be called motion graphics, the term typically more explicitly refers to the commercial application of animation and effects to video, film, TV, and interactive applications.
The Computer Originated World (COW) was the method of creating the BBC1 symbol that was used between 18 February 1985 and 16 February 1991. It was later used by the international, commercial television service BBC World Service Television from its launch until 26 January 1995.

Digital video effects (DVEs) are visual effects that provide comprehensive live video image manipulation, in the same form as optical printer effects in film. DVEs differ from standard video switcher effects such as wipes or dissolves, in that they deal primarily with resizing, distortion or movement of the image. Modern video switchers often contain internal DVE functionality. Modern DVE devices are incorporated in high-end broadcast video switchers.

The history of computer animation began as early as the 1940s and 1950s, when people began to experiment with computer graphics – most notably by John Whitney. It was only by the early 1960s when digital computers had become widely established, that new avenues for innovative computer graphics blossomed. Initially, uses were mainly for scientific, engineering and other research purposes, but artistic experimentation began to make its appearance by the mid-1960s – most notably by Dr. Thomas Calvert. By the mid-1970s, many such efforts were beginning to enter into public media. Much computer graphics at this time involved 2-D imagery, though increasingly as computer power improved, efforts to achieve 3-D realism became the emphasis. By the late 1980s, photo-realistic 3-D was beginning to appear in film movies, and by mid-1990s had developed to the point where 3-D animation could be used for entire feature film production.
