节奏具有普遍性，它不仅仅存在于自然和生活中，也存在于艺术当中。不同的艺术门类有着不同的传播媒介，节奏随着传播媒介的发展变化，呈现出具有媒介属性的特性。文学节奏附属于语言文字的变化中，绘画节奏体现在形状、大小、色彩、明暗等关系的对比之上，戏剧节奏主要在演员的表演变化中呈现，电影节奏则由镜头与蒙太奇来体现。

而随着虚拟现实技术的发展，虚拟现实与电影的结合成为内容创新的突破口，为观众带来全新观影体验的同时，也为创作者提出了严峻挑战。新的媒介改变了电影的呈现方式，造成传统的叙事表达手段与视听规则失效，节奏叙事效果不尽人意。

本文结合虚拟现实的媒介属性，通过与传统电影节奏特性作对比，总结了CVR电影的内部节奏与外部节奏的转向特性。首先采用了文本分析的方法，选取优质电影案例进行深入分析，梳理出四种虚拟现实电影节奏的设计特点，分别是沉浸式开场、人物入场方式、关键情节点的节奏变化以及转场的节奏设计四个方面。并在此基础上，采用实证研究手段，从电影叙事效果方面对这四种节奏设计手段的适用性与合理性进行验证。采用组间设计进行实验研究，选取节奏设计不合理的CVR影片做变量控制，对观众观影后的细节记忆与剧情理解进行分析，对比节奏的叙事效果的差异性，结果发现节奏的调整明显提高了用户对影片细节记忆的正确率。

Rhythm is universal, which not only exists in nature and life, but also exists in art. Different art categories have different communication media, and the rhythm changes with the development of the communication media, showing the characteristics of media attributes. Literary rhythm is attached to the change of language and writing. The rhythm of painting is embodied in the contrast of shapes, sizes, colors, light and shade, etc. The rhythm of drama is mainly presented in the performance changes of actors, and the rhythm of film is embodied by shots and montages.

With the development of virtual reality (VR) technology, the combination of virtual reality and film has become a breakthrough in content innovation, which not only bringing a new viewing experience to audiences, but also posing severe challenges for creators. The new medium has changed the way the film is presented, causing the failure of traditional narrative expression methods and audio-visual rules, and the effect of rhythmic narration is not satisfactory.

Combining the media attributes of virtual reality, this paper summarizes the turning characteristics of the internal and external rhythms of CVR movies by comparing with traditional movie rhythm characteristics. First, the text analysis method is adopted, and high-quality movie cases are selected for in-depth analysis, and four design characteristics of the rhythm of virtual reality movies are sorted out. They are the immersive opening, the way the characters enter the scene, the rhythm of the key plot points, and the rhythm of the transition. Four aspects of design. And on this basis, empirical research methods are used to verify the applicability and rationality of these four rhythm design methods from the perspective of film narrative effects. Use the inter-group design for experimental research, and selected CVR movies with unreasonable rhythm design as variable control, then analyzed the audience's detailed memory and plot understanding after watching the movie, and compared the difference in the narrative effect of the rhythm. As a result, we found that the adjustment of the rhythm significantly improves the user’s correct memory of the details of the film rate.
