【摘要】：在大数据时代,信息呈爆炸式增长。蒙古语新闻网站增长迅速、内容丰富,各网站的新闻素材数据越来越多。为了进一步促进蒙古族地区传媒教育的发展,帮助培养更多的蒙古族新闻采编人才,实时跟踪海量的蒙古语新闻素材,设计实现蒙古语新闻媒介融合平台成为亟待解决的问题。蒙古语新闻媒介融合平台的整体设计架构如下。首先从固定蒙古语网站和相关汉语网站爬取素材资源,对素材进行分词等预处理后按媒体类型进入数据库,再对素材资源按照内容等主题聚类后返回数据库,在网站前端按照主题进行素材资源展示,学生可以按照兴趣进行素材下载,下载后可以通过视频非线性编辑软件系统对素材进行重新编辑并发布。为了能够对这些新闻视频素材进行重新编辑,本文对蒙古语新闻媒介融合平台中的视频非线性编辑关键内容展开了应用研究,主要进行了以下两方面工作:第一、调研提供素材源的蒙古语新闻网站。充足的蒙古语新闻素材资源是对相关蒙古语新闻进行重新编辑的基础。因此,笔者首先对蒙古语新闻网站做了调研,包括中国蒙古语新闻网、人民网蒙文版、赤峰蒙古语新闻网等13个蒙古语新闻网站。这些蒙古语新闻网站拥有大量的视频、音频、图片等新闻素材资源,其中,视频素材的主要格式为FLV、MP4等;音频素材的主要格式为MP3等;图片素材的主要格式为JPG等。对蒙古语新闻网站的调研为下一步蒙古语新闻视频的非线性编辑做了充分准备。第二、实现蒙古语新闻视频非线性编辑软件系统。现有的视频非线性编辑软件都只有30天左右的试用期,并且EDIUS内部没有直接提供蒙古语竖版字幕模板。因此,笔者对开源程序Openshot和Inkscape进行整合优化,实现了一个面向蒙古语新闻视频非线性编辑的软件系统。首先,对原程序界面中的一些英文进行了中文翻译,包括Title、Video Format等。其次,对界面中部分复杂子项目进行了重新优化组合,利用qt designer软件对帮助下拉菜单的子项目进行了重新组合。另外,利用蒙古语镜像字体和Inkscape开源程序实现了蒙古语字幕的竖版显示,并对系统的素材区添加了图像窗口等。最终对程序进行重新打包,生成exe格式的安装包。本文对设计实现的软件系统进行了一系列的功能测试,测试结果表明,本系统可以满足初学者对蒙古语新闻视频非线性编辑的基本需求。
[Abstract]:In the age of big data, information has exploded. Mongolian news website grows rapidly, the content is rich, the news material data of each website is more and more. In order to further promote the development of media education in Mongolian areas, help train more Mongolian news editors, track a large amount of Mongolian news materials in real time, design and realize Mongolian news media fusion platform become an urgent problem to be solved. The overall design framework of Mongolian news media fusion platform is as follows. First, crawling the material resources from the fixed Mongolian websites and related Chinese websites, pretreating the material with word segmentation and entering the database according to the media type, then returning the material resources to the database after clustering according to the content and other topics. In front of the website according to the theme of material resources display, students can download according to their interest, after downloading, the material can be reedited and published through the video non-linear editing software system. In order to reedit these news video materials, this paper studies the key content of nonlinear video editing in Mongolian news media fusion platform. The main works are as follows: first, Research provides a source of material for Mongolian news sites. Adequate Mongolian news material resources are the basis of reediting Mongolian news. Therefore, the author first made a survey on Mongolian news websites, including 13 Mongolian news websites, such as China Mongolian News Network, people's net Mongolian version, Chifeng Mongolian News Network and so on. These Mongolian news websites have a large number of news material resources, such as video, audio, pictures, etc. Among them, the main format of video material is FLV MP4, the main format of audio material is MP3, the main format of picture material is JPG and so on. The research on Mongolian news website provides the next step for nonlinear editing of Mongolian news video. Second, the realization of Mongolian news video nonlinear editing software system. The existing video nonlinear editing software only has a trial period of about 30 days, and Edus does not provide Mongolian Vertical subtitle template directly. Therefore, the open source program Openshot and Inkscape are integrated and optimized, and a software system for nonlinear editing of Mongolian news video is implemented. First of all, some English translations are carried out in the original program interface, including title Video format and so on. Secondly, some complex subitems in the interface are recombined, and the subitems that help the drop-down menu are recombined by using QT designer software. In addition, Mongol mirror font and Inkscape open source program are used to realize the vertical display of Mongolian subtitles, and the image window is added to the material area of the system. Finally, the program is repackaged to generate the exe format of the installation package. In this paper, a series of functional tests are carried out on the software system designed and implemented. The results show that the system can meet the basic needs of Mongolian news video nonlinear editing for beginners.
