The videos made through mobile phones are probably changing the way we think of videos created to tell or show something, both imaginary tales or private movies, or even chronicles of events to spread rapidly through the web. A change has already occurred in the use, as the new digital portable devices allowed to concentrate on a single medium a variety of media with various functions. Therefore, a tool like the telephone has been enhanced with new features typically designed for other media.In this process of appropriation, new mobile devices changed the way these new features are being used, due, of course, to new conditions. Other than multiplying the production of images that one would call "dirty" due to the presence of rough movements, continuous zoom in and zoom out and, of course, broadcast sub-standard video quality, the new tools introduced the practice of vertical shooting, so inducing a habit.In the history of photography, however, the two formats, landscape and portrait, have always lived together. This paper aims to analyze, briefly, a situation in rapid and continuous evolution, also characterized by the presence of new paradigms responding to visual aesthetic rules that are gradually being defined.

屏幕格式上的“移动效果”：垂直视频的案例

通过手机拍摄的视频可能正在改变我们对视频的描述方式，无论是虚构的故事还是私人电影，甚至是事件编年史，都可以通过网络传播。使用方面已经发生了变化，因为新的数字便携式设备允许将具有各种功能的各种媒体集中在一个媒体上。因此，电话之类的工具已得到增强，具有通常为其他媒体设计的新功能。在此使用过程中，新移动设备当然会由于新条件而改变了使用这些新功能的方式。除了由于粗略的运动，连续放大和缩小以及当然广播质量不佳的视频而使人们称之为“肮脏”的图像的产生倍增之外，新工具引入了垂直拍摄的实践，从而养成了一种习惯。然而，在摄影史上，风景和肖像这两种格式一直生活在一起。本文旨在简要分析快速连续发展的情况，其特征还在于响应于逐渐被定义的视觉美学规则的新范例的出现。
