Videos - in this case video clips , or short digital videos with background music - are self-produced as a direct expression of its author , with the addition
of original electronic music tracks . In general , videos offer something more than just a picture , in terms of understanding , reworking and final learning .
They are mainly of two genres , one spoken and one musical , with fixed or moving backgrounds that in each case present a succession of one or more images while
still creating the desired effect. To get an idea of a person or a place a picture is almost never enough , which is why there is such a massive spread of video
both in terms of web recordings and as a means of communication between two or more people live. The audio quality and resolution of the footage then is very
important because good listening and sharp viewing allow for a full appreciation of the content.
