Internet video media are arising and taking the place of television. The basis of the characteristics of online video is interactivity. This characteristic has enabled individuals to send video content to the world and has created new genres such as video blogs and gameplay. In addition, while daily communication through images is promoted, videos that capture decisive moments are easily diffused, which has various impacts on society. Online video has the advantage that the sender can also obtain the information of the receiver. Improving the content by analyzing the viewer retention rate and creating the content according to the role can make full use of the characteristics of the video.

With the widespread use of cameras and the low cost and widespread use of personal computers for editing and processing video files, video production has become more accessible and not just for professionals. At the same time, the expansion of online classes in the corona disaster has accelerated the production of video content for lectures in education, forcing many educators to become involved in video production. However, the scope of video production is wide and includes everything from multimillion-dollar Hollywood movies to short videos of less than a few tens of seconds such as TikTok, with a wide range of production ideas and methods. In this paper, I will explain the production flow and summarize the basic knowledge based on public relations (information) and lecture delivery, which are mainly intended for use in universities.

Due to space limitations, in this paper, the author discusses the points of video creation.

In the process of film production and distribution, different types of data are generated due to the amount of information, formats, and characteristics for different purposes of use. Similarly, multiple types of media for storing these data are also generated for backup purposes, depending on the intended use. How to classify and manage these variations of data and media is an important point when considering an optimized database management for the purpose of digital preservation of the cinema. This paper focuses on a structure of database for managing the Digital Cinema with specific examples of the policy under consideration at the National Film Archive of Japan.

The Digital Information Department (DID) of the National Diet Library (NDL), Japan, was established in October 2011 to handle operations related to information systems smoothly and efficiently.
