数字视频正变得越来越普遍。然而，由于以下几个原因，编辑视频仍然很困难：它是一种基于时间的媒体，它具有音频和视频的双轨，并且当前的工具迫使用户在最小的细节级别上工作。基于对专业视频编辑的采访，我们开发了一个名为银的视频编辑器，它使用元数据使新手更容易进行数字视频编辑。为了帮助用户可视化视频，银提供了具有不同语义内容和不同抽象级别的多个视图，包括故事板、可编辑脚本和时间轴视图。银提供智能编辑操作，帮助用户解决由于音频和视频的不同边界而产生的不一致性。我们进行了初步用户研究，以调查银智能编辑的有效性。参与者仅在简短的教程后就成功编辑了视频，无论是否有智能编辑帮助。我们的研究提出了几种方法，视频编辑工具可以使用元数据来帮助用户重用和合成视频。
Digital video is becoming increasingly ubiquitous. However, editing video remains difficult for several reasons: it is a time-based medium, it has dual tracks of audio and video, and current tools force users to work at the smallest level of detail. Based on interviews with professional video editors, we developed a video editor, called Silver, that uses metadata to make digital video editing more accessible to novices. To help users visualize video, Silver provides multiple views with different semantic content and at different levels of abstraction, including storyboard, editable transcript, and timeline views. Silver offers smart editing operations that help users resolve the inconsistencies that arise because of the different boundaries in audio and video. We conducted a preliminary user study to investigate the effectiveness of the Silver smart editing. Participants successfully edited video after only a short tutorial, both with and without smart editing assistance. Our research suggests several ways in which video editing tools could use metadata to assist users in the reuse and composition of video.
