**4. Structure of video**

Note that the structure of video materials is always subject to the genre in which they are created. If we take as a basis the criterion of the purpose of creating video materials, then all video materials can be divided into two large groups: (1) video materials that are not adapted for use in the educational process and (2) video materials prepared specifically for use in the educational process. The first group consists of video materials, the creation of which was not subject to educational purposes. These are materials purchased or recorded from television, news programs, weather forecasts, advertisements, feature films and documentaries, sports programs, etc. This includes the entire range of television products offered by modern television. The second group includes educational feature and documentary films, as well as video courses.

Video courses have a diverse structure. As a rule, this is a series of video lessons, united by a common storyline, having common characters.

In addition, some common features can be identified in the structure of various video courses. One of these features, in our opinion, is, for example, the presence of a detailed and fragmented exposition in the structure of video courses. These concepts were proposed by I. Salistra [14] to characterize the structure of film materials. We believe that these structural components are quite applicable for video courses. The detailed exposition is a film novella, and the fragmentary exposition is presented in the form of separate situations. The purpose of the expanded exposition is the initial presentation of the material. The purpose of the fragmentary exposition is a detailed and in-depth presentation of lexical and grammatical material.

Concluding the consideration of the structural features of video materials, we note that their structure should be maximally correlated with the educational purposes of the demonstration. To achieve the objectives of the lesson, the structure of video materials during the demonstration process can be changed in accordance with the principles of using video materials, which we will consider in the next section of the study.
