基于剪辑元素属性约束的可计算产品展示视频自动剪辑框架

Computational Product Presentation Video Editing Framework Based on Editing Attribute Constraints

  • 摘要: 当前电商领域爆发了对产品展示视频的海量需求.而视频剪辑是视频制作中至关重要的一环.产品展示视频的剪辑比其他类别视频具有更强的信息传达目的.从信息传达效果出发,结合专家访谈和用户实验,得出信息排布、剪辑连贯、剪辑节奏、片段节奏4个影响消费者信息感知的剪辑元素,并应用这4个剪辑元素构建了基于剪辑元素属性约束的自动剪辑框架.首先将镜头素材在信息类别、片段节奏与剪辑节奏的约束下分割成片段;然后应用隐马尔可夫模型与全局约束的维特比算法获取最佳的片段序列,以呈现合适的目标信息并兼具视觉连贯;最后,开发了一个针对服装的自动剪辑系统原型,支持对多段素材的即时分割和成片输出.与专业人工剪辑结果比较发现,该方法能更高效地帮助制作者完成视频剪辑,且视频效果接近人工剪辑.

     

    Abstract: Nowadays,there is an obvious increasing demand for product presentation videos(PPVs)in the field of e-commerce.In order to produce high-quality PPVs,the importance of video editing has been emphasized.When comparing with video editing for advertising,PPVs pay more attention to the product information.Considering the effect of information transfer,we conducted two experiments to explore the factors(information arrangement,editing coherence,editing rhythm and mise-en-scène rhythm)that affect consumers’information perception.We applied those elements to build an automatic editing framework based on editing attribute constraints.We at first divided footages into clips under the constraints of information type,mise-en-scène rhythm and duration.Then we use the hidden Markov model and the Viterbi algorithm with global constraints to realize clips editing.Finally,we developed an automatic editing system prototype for the garments.Compared with the professional hand-edited result,our method can complete video editing more efficiently,and our outputs are quite close to the hand-edited result.
