Film is a term that encompasses individual motion pictures, the field of film as
an art form, and the motion picture industry. Films are produced by recording
images from the world with cameras, or by creating images using animation
techniques or special effects. Films are cultural artifacts created by specific
cultures, which reflect those cultures, and, in turn, affect them. Film is
considered to be an important art form, a source of popular entertainment, and a
powerful method for educating -or indoctrinating- citizens. The visual elements
of cinema give motion pictures a universal power of communication; some movies
have become popular worldwide attractions, by using dubbing or subtitles that
translate the dialogue. Traditional films are made up of a series of individual
images called frames. When these images are shown rapidly in succession, a
viewer has the illusion that motion is occurring. The viewer cannot see the
flickering between frames due to an effect known as persistence of vision —
whereby the eye retains a visual image for a fraction of a second after the
source has been removed. Viewers perceive motion due to a psychological effect
called beta movement. The origin of the name "film" comes from the fact that
photographic film (also called film stock) has historically been the primary
medium for recording and displaying motion pictures. Many other terms exist for
an individual motion picture, including picture, picture show, photo-play,
flick, and most commonly, movie. Additional terms for the field in general
include the big screen, the silver screen, the cinema, and the movies.
Video (Latin for "I see", first person singular present, indicative of videre,
"to see") is the technology of electronically capturing, recording, processing,
storing, transmitting, and reconstructing a sequence of still images
representing scenes in motion. Video technology was first developed for
television systems, but has been further developed in many formats to allow for
consumer video recording. Video can also be viewed through the Internet as video
clips or streaming media clips on computer monitors.
Television (often abbreviated to TV, T.V.; sometimes called the tube, or telly
in the UK) is a widely used telecommunication system for broadcasting and
receiving moving pictures and sound over a distance. The term may also be used
to refer specifically to a television set, programming or television
transmission. The word is derived from mixed Latin and Greek roots, meaning "far
sight": Greek τῆλε "tele", far, and Latin vision, sight (from video, vis- to
see).Since it first became commercially available from the late 1930s, the
television set has become a common household communications device in homes and
institutions, particularly in the first world, as a source of entertainment and
news. Since the 1970s, video recordings on VCR tapes and later, digital playback
systems such as DVDs, have enabled the television to be used to view recorded
movies and other programs.A television system may be made up of multiple
components, so a screen which lacks an internal tuner to receive the broadcast
signals is called a monitor rather than a television. A television may be built
to receive different broadcast or video formats, such as high-definition
television (HDTV). Learn Film Video Television, SCHOOLS Film Video Television,
