Video

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.

Video systems vary greatly in the resolution of the display, how they are refreshed, and the rate of refreshed, and 3D video systems exist. They can also be carried on a variety of media, including radio broadcast, tapes, DVDs, computer files etc.

History

Video technology was first developed for Mechanical television systems, which were quickly replaced by cathode ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Charles Ginsburg led an Ampex research team developing one of the first practical video tape recorder (VTR). In 1951 the first video tape recorder captured live images from television cameras by converting the camera's electrical impulses and saving the information onto magnetic video tape.

Video recorders were sold for $50,000 in 1956, and videotapes cost $300 per one-hour reel. However, prices gradually dropped over the years; in 1971, Sony began selling videocassette recorder (VCR) decks and tapes to the public.

Stop motion

Stop motion is an animation technique that physically manipulates an object that appears to move on its own. The object is moved in small increments between individually photographed frames, creating the illusion of movement when the series of frames is played as a continuous sequence. Dolls with movable joints or clay figures are often used in stop motion for their ease of repositioning. Stop motion animation using plasticine is called clay animation or "clay-mation". Not all stop motion requires figures or models; many stop motion films can involve using humans, household appliances and other things for comedic effect. Stop motion using objects is sometimes referred to as object animation.

Terminology

The term "stop motion", related to the animation technique, is often spelled with a hyphen, "stop-motion". Both orthographical variants, with and without the hyphen, are correct, but the hyphenated one has, in addition, a second meaning, not related to animation or cinema: "a device for automatically stopping a machine or engine when something has gone wrong" (The New Shorter Oxford English Dictionary, 1993 edition).

Dumb Ways to Die

Dumb Ways to Die is an Australian public service announcement campaign by Metro Trains in Melbourne, Victoria, Australia, to promote rail safety. The campaign video went viral through sharing and social media starting in November 2012.

Campaign

The campaign was devised by advertising agency McCann Melbourne. It appeared in newspapers, local radio, outdoor advertising, throughout the Metro Trains network and on Tumblr. John Mescall, executive creative director of McCann, said “The aim of this campaign is to engage an audience that really doesn't want to hear any kind of safety message, and we think Dumb Ways To Die will.” McCann estimated that within two weeks, it had generated at least $50 million worth of global media value in addition to more than 700 media stories, for "a fraction of the cost of one TV ad". According to Metro Trains, the campaign contributed to a more than 30% reduction in "near-miss" accidents, from 13.29 near-misses per million kilometres in November 2011 – January 2012, to 9.17 near-misses per million kilometres in November 2012 – January 2013.
