Video Definition

Video is a technology used to capture, record, process, transmit and reproduce a sequence of images representative of a scene that is in motion . The term, which comes from the Latin "see", is currently associated with different storage formats, whether analog (VHS and Betamax) or digital (MPEG-4, DVD, Quicktime, etc). But, from the old VHS cassettes to today's massive YouTube videos, there is a long way.

The beginnings of the video are related to the attempt to cover the needs of television . Indeed, the first television broadcasts were performed live, and with the possibility of recording them, the programming work was greatly facilitated; In this sense, the Tokyo Olympics in 1964 were the first case in which a deferred transmission is made. Already at the end of the seventies it is definitely consolidated as an independent television technology.

For this development, the commercialization , by the Sony Corporation, of the first portable camera in 1968 was of utmost importance . Then, in 1970, Philips sold the VCR, adding new possibilities for an ordinary person.

If at the beginning, these cameras had a privileged use in large television studios, then they began to be produced for sale to anyone. With them you could record events, such as parties or use them on trips. Undoubtedly, with the rapid advance of electronic technology from the mid-1960s, in general electronic devices were able to perform much more malleable measures for personal and everyday use, and so there are currently small cameras no more than 10 centimeters high which can be moved without inconvenience even in the pocket of a jacket or pants.

A separate section deserves the coexistence between cinema and video. At first, it was considered that the new technological possibilities offered by the video would completely eradicate the seventh art. However, these predictions were never fulfilled, both alternatives being able to complement each other perfectly, thanks to the policies used by the large studios.

Storage technology such as DVDs cannot be overlooked in a chronology of video life. In this format , millions of movies are stored and transported every year and even videos or homemade presentations can be made, for example when we make a video to play at a birthday party. Today we even have the most advanced Blu-Ray technology at your fingertips, which can store a considerable amount of gigabytes, far exceeding the possibilities and benefits of the DVD.

Nowadays, with the proliferation of digital media, the use of videos has reached a massive character that has hardly been dreamed of four decades ago . With the current use of the Internet, it is possible to appreciate personal videos of people from all over the world. The other important point to consider is the lowering of the technological means of recording, which are becoming more accessible every day. Obviously, the future looks promising if we also consider the progress made in quality.

If Giovanni Sartori defined the post-war era as the "video sphere", he was not too wrong. The videos that upload millions of users to a social network like YouTube, and the billions of visits that some videos receive, are the most complete example of this importance that the image has gained in the modern world (since the second half of the twentieth century) . Many television channels even invite and encourage the participation of their viewers to be "correspondents" recording videos of events or events in their cities and send them as informative material. A worldwide impact event, in which the videos recorded by citizens who were there at that time, was the attack on Wall Street to the Twin Towers on September 11, 2001.
