They are a series of images that are captured by a camera, which go through a production and editing process; they are mainly called frames, which can be accompanied by sound. It was developed mainly for the first television projects.
The first instrument designed to record sequences and to be able to reproduce them later, was called the VCR, and it stored the files that were previously recorded on a magnetic tape; was born from the need to record the news at night in the United States, because on the west coast it was too early to transmit it at the same time on the east coast -In the US there are 5 different time zones-, so the method used was to record the broadcast in 35 mm format, and then it was reproduced through the Telecine.
With the appearance of video, television programs were no longer so frequently broadcast live, most were recorded, edited, and broadcast at the scheduled time. Most of today's television programs are pre-recorded and the technology even allows a cable television user to record television and view it later.
Nowadays, videos have evolved and can be found in different formats, such as VHS and Betamax, as well as digital, the most popular of the moment, such as DVD and MPEG-4. The quality of the videos derive from the type of recorder that is used to record, in addition to the type of storage that can be given. Likewise, various techniques can be used to compress the video, thus making it easier to distribute. In order for the magnetic tape to project the frames clearly, the camera captures light and color, the first one is used to define the image in white and the second one for, according to the different standards by which a country is governed, decode the color.

Like "vlogs" , a term applied to small productions made by ordinary people who seek to touch on a topic of social, economic, political, cultural or daily importance.
