There are various kinds of learning systems in the world and quite a lot of them are using video sources. Also, those video sources have many kinds according to the content of learning and aim. In this paper, I'd like to describe the usability of learning systems by using a super high definition video source focusing on making handling of video source using super high resolution. Furthermore, the future progress and present problems would be considered by proposing an on-demand learning system using a super high definition video source. The super high resolution here means 4K (4096×2160 dots).
