This document defines several technical terms related to film and video formats including cross-promotion, cross media, frame size, resolution, HD, 2K/4K, DCP, aspect ratio, 3D film, and 4D film. It explains that cross-promotion involves surpassing traditional advertising with extra appeals. Cross media refers to different technologies evolving to perform similar tasks. It also defines pixel dimensions, resolution, high definition, and digital cinema package. Aspect ratios, 3D using stereoscopy, and 4D combining 3D with physical effects are also summarized.

 Resolution- The number represents the number of horizontal lines the video has from top to

resolution of 2K.
 DCP- This is a Digital, Cinema, Package this is a collection of digital files used to store and convey
digital cinema audio, image and data streams.
 Aspect ratio- This refers to the width of a picture (or screen) in relation to its height. Ratios are
expressed in the form “width X height”. For example, a 4X3 ratio means the picture is 4 units wide
by 3 units high.
 3D film- This is a motion picture that enhances the illusion of depth perception, hence adding a
third dimension. The most common approach to the production of 3D films is derived from
stereoscopic photography.
 4D film- This is a marketing term for an entertainment presentation system combining a 3D film
with physical effects that occur in the theatre in synchronization with the film. Effects in a 4D film
may include rain, wind, strobe lights and vibrations.
