Multimedia. Multimedia is a form of communication that uses a combination of different content forms, such as writing, audio, images, animations, or video, into a single interactive presentation, in contrast to traditional mass media, such as printed material or audio recordings, which feature little to no interaction between users.
Linear video editing. Linear video editing is a video editing post-production process of selecting, arranging, and modifying images and sound in a predetermined, ordered sequence. [1] Regardless of whether it was captured by a video camera, [2] tapeless camcorder, or recorded in a television studio on a video tape recorder (VTR) the content ...
Video editing. Video editing is the post-production and arrangement of video shots. To showcase perfect video editing to the public, video editors must be reasonable and ensure they have a superior understanding of film, television, and other sorts of videography. [1] Video editing structures and presents all video information, including films ...
Hypermedia, an extension of the term hypertext, is a nonlinear medium of information that includes graphics, audio, video, plain text and hyperlinks. This designation contrasts with the broader term multimedia, which may include non-interactive linear presentations as well as hypermedia. It is also related to the field of electronic literature.
Non-linear media is a move away from traditional linear media, in which content is selected by the publisher to be consumed and is then done so passively. [1] [2] [3] There is no single specific form of non-linear media; rather, what might be considered non-linear changes as technology changes. Following the development and rise of digital non ...
Macroblock. The macroblock is a processing unit in image and video compression formats based on linear block transforms, typically the discrete cosine transform (DCT). A macroblock typically consists of 16×16 samples, and is further subdivided into transform blocks, and may be further subdivided into prediction blocks.

Luma is the weighted sum of gamma-compressed R′G′B′ components of a color video—the prime symbols ′ denote gamma compression. The word was proposed to prevent confusion between luma as implemented in video engineering and relative luminance as used in color science (i.e. as defined by CIE ). Relative luminance is formed as a weighted ...
