A cloud-based collaborative and automatic video editor

Automatic video editing is a hot topic because of the rapid growth of video. In this paper we present a cloud-based tool and an approach of automatic video editing based on keywords extracted from the audio transcription. Using algorithms of semantic analysis of transcript texts and constraints of the composed video duration or mashup, video sequences are selected and chained to create automatically a new video. A cloud based video editor allows users collaboratively editing the video.
