“…According to literature, the workflow to create a lecture recording is divided into four phases (Huerst, Mueller, & Ottmann, 2006;Mertens, Ketterl, & Vornberger, 2007). The phases are separated chronologically and must be run through step by step.…”

Lectures of courses at universities are increasingly being recorded and offered through various distribution channels to support students' learning activities. This research work aims to create an automatic system for producing and distributing high quality lecture recordings. Opencast Matterhorn is an open source platform for automated video capturing and distribution and will be integrated fully in the introduced system. Beside lecture recordings

“…Audio recordings of live lectures together with screen capture videos of the material presented on a data projector in the classroom have become quite popular at universities – especially in technical disciplines such as computer science, where electronic slides are commonly used (Hürst et al , 2006). Using touch screens, Tablet PCs, or simple graphics tablets, lecturers can make annotations on the electronic slides that are also automatically recorded and shown in real‐time later during playback along with the original slide content and the synchronized audio recording (Friedland et al , 2008).…”

PurposePlaying back recorded lectures on handheld devices offers interesting perspectives for learning, but suffers from small screen sizes. The purpose of this paper is to propose several semi‐automatic post‐processing steps in order to improve usability by providing a better readability and additional navigation functionality.Design/methodology/approachSeveral rather simple (and thus fast) statistical indicators were implemented and evaluated to detect certain events in a lecture recording that can be used in a semi‐automatic post‐processing approach.FindingsThe evaluations verify the quality of the analysis. By presenting an actual implementation, the paper demonstrates how these results can be used to improve visibility of the content and provide further navigation options, thus increasing overall usability.Originality/valueThis paper provides practical information on how to build a useful system for everyday usage in normal teaching scenarios. The paper presents different approaches illustrating initial steps for achieving better visualization and navigation functionality for lecture podcast – two issues that are essential for their usability but have not found much attention so far. This implementation demonstrates the usefulness and feasibility of the proposed techniques. Although the purpose of this article is rather on practical aspects than on presenting new research results, some of the observations can have implications for research in this area and some results illustrate important aspects and interesting research opportunities.
