This presentation at DH Benelux 2019, receiving one of the two best paper awards, includes findings of the ReVI project. This was a pilot looking at enhancing the Resource Viewer of the CLARIAH Media Suite, where audiovisual materials can be played. Specifically, the ReVI project looked at optimal ways "to support the exploration of different types of content metadata of audiovisual sources, such as segment information or automatic transcripts." During the project, various design thinking sessions were conducted, and a prototype including temporal content visualizations of audiovisual materials was created and evaluated in a user study. The findings of the user study showed a clear value of temporal visualizations and advanced annotation features for research purposes, as well as the continued importance of a data and tool criticism approach. New content exploration tools can benefit scholars doing research with audiovisual sources, for instance in media studies, oral history, film studies, and other disciplines which are increasingly using audiovisual media. The findings documented in the DH Benelux 2019 paper may serve as an inspiration for improving AV-media-based research tools. Concretely, it will also inform the further enhancement of the Resource Viewer of the CLARIAH Media Suite.
