Data videos are becoming increasingly popular in society and academia. Yet little is known about how to create endings that strengthen a lasting impression and persuasion. To fulfill the gap, this work aims to develop guidelines for data video endings by drawing inspiration from cinematic arts. To contextualize cinematic endings in data videos, 111 film endings and 105 data video endings are first analyzed to identify four common styles using the framework of ending punctuation marks. We conducted expert interviews (N=11) and formulated 20 guidelines for creating cinematic endings in data videos. To validate our guidelines, we conducted a user study where 24 participants were invited to design endings with and without our guidelines, which are evaluated by experts and the general public. The participants praise the clarity and usability of the guidelines, and results show that the endings with guidelines are perceived to be more understandable, impressive, and reflective.

数据视频在社会和学术界越来越受欢迎,但很少有人知道如何创建有持久印象和说服力的结尾。为了填补这一空白,本研究旨在通过从电影艺术中汲取灵感,制定数据视频结尾的指导方针。为了将电影结尾的上下文化在数据视频中,首先分析了111个电影结尾和105个数据视频结尾,使用了结尾标点符号的框架,以确定四种常见风格。我们进行了11名专家的访谈,并制定了20个创造电影式结尾的数据视频的指导方针。为了验证我们的指导方针,我们进行了一项用户研究,邀请24名参与者设计具有和不具有我们的指导方针的结尾,并由专家和公众进行评估。参与者赞扬了指导方针的清晰度和可用性,结果显示有指导的结尾更容易理解,给人留下更加深刻的印象并具有反思性。
