Re-use of Media Fragments

Fragment Re-UseAs an example of media fragment re-use, in the current video production for news, commercials or magazines the editors re-use materials from footage providers such as Getty Images, ITN Source, Video Clipdealer, Insertstock, Istockphoto, NBC archives and Thought Equity Motion. They all offer complete "clips" from a few seconds up to several minutes with metadata such as source, title, time, place, persons and categorie (natur, technic, sports, etc.), rating and more. But as all meta data are manually defined by editors in a very costly process, only a small part of the available video content can be offered.

Therefore the MediaMixer project envisages to exploit a much wider range of video footage by offering fragments through automatic annotation by visual, textual and speech analysis as well as face recognition. Additional meta data are inherited for each fragement from previous or related shots, scenes or the complete video. The link to the fragment source usually allows to determine crucial parameters, such as owner, price and creation time. Media fragments can be video snippets of any size from single frames or shots to several scenes. However, the automatic annotation process does not allow to annotate each fragment with all meta data provided for the clips, as for example time or place can often not be identified for each part of the video.

The MediaMixer project envisages a complementary use of Clip archives and Media Fragments retrieval: If the search in clip archives with a smaller number of clips was not successful, the Media Fragments retrieval allows to browse through a much wider range of footage, but - due to the less complete annotations - in a more explorative way by using recommender algorithms, similarity search and personalization.

The re-use of video footage is supported by the tools offered from the MediaMixer community as well as any other available tools, which can be employed in the user application environment to generate, retrieve and present Media Fragments. The user interfaces will be designed according to the needs of editors to re-use Media Fragments in their application environment such as news production, learning, advertisement, documentary, product presentation.
