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.
Video art is a type of art which relies on moving pictures and is comprised of video and/or audio data. (It should not however be confused with television or experimental cinema). Video art came into existence during the 1960s and 1970s, is still widely practised and has also given rise to the widespread use of video installations.
Video resolution
The size of a video image is measured in pixels for digital video or horizontal scan lines and vertical lines of resolution for analog video. In the digital domain (e.g. DVD) standard-definition television (SDTV) is specified as 720/704/640×480i60 for NTSC and 768/720×576i50 for PAL or SECAM resolution. However in the analog domain, standard definition equates to about 240×480 (NTSC) or 240×576 (PAL) pixels for VCR quality, to 400×480 (NTSC) or 400×576 (PAL) pixels for TV broadcasts (i.e. the number of horizontal scanlines [from top to bottom] remain constant, but the horizontal resolution [from left to right] varies). Aspect ratio is preserved because of non-square "pixels". read more.......
