In video content analysis, growing research effort aims at characterising a specific type of unedited content, called rushes. This raw material, used by broadcasters and film studios for editing video programmes, usually lies un-annotated in a huge database. In this work we aim at retrieving a desired type of rush by representing the whole database content in a multimodal space. Each rush content is mapped into a trajectory whose coordinates are connected to multimodal features and filming techniques used by cameramen while shooting. The trajectory evolution over time provides a strong characterisation of the video, so that different types of rushes are located into different regions of the multimodal space. The ability of the proposed method has been tested by retrieving similar rushes from a large database provided by EiTB, the Basque Country main broadcaster.
