Following that path, UPV applied as a member of the Opencast community for Lecture Capture and has used Opencast for several years. Being Opencast an Open Source project gives adopters a great amount of flexibility, UPV is using actively Opencast for different educational projects, like Lecture Capture, Flipped Teaching and MOOC production. Results of the experience shows that Opencast is a proper choice for educational support, and also that satisfaction and academic results of the experience are quite good and no doubt a valuable improvement in a University environment. Keywords Video, lecture capture, educational technology, flipped teaching Context and Objectives Universitat Politècnica de València (UPV) is a 35,000 students’ higher educational institution in Spain, which has been interested for quite a long time in the application of technology into learning. Following that path, UPV applied as a member of the Opencast community for Lecture Capture and has used Opencast for several years. Opencast is an international community (Opencast, 2016), member of the Apereo network of institutions (Apereo, 2016), interested in developing systems and software related to Lecture Recording in education. Opencast is also the name of the open source lecture capture and video management system which allows institutions to capture, process, manage and distribute video assets on a large scale. It plays with relevant academic systems and services and provides flexibility to meet the diversity of video management requirements we see today. Thus, a university can have a working Opencast system deploying capture agents in the lecture halls to record simultaneously the teacher’s video, audio and the screen that the teacher shows in the computer in the classroom, creating a multi-track recording, which can then be ingested and published through the core system. Opencast, being an open source project allows an enormous amount of flexibility in the components deployed and the way of using them, so there each installation is somewhat unique. Here are the main choices for an opencast deployment: Capture agent: the capture agent is the computer that actually records the video and audio in the lecture hall. There are different brands and programmes, both commercial and open source that provide such equipment. Sound system: The sound system is related on how you capture the audio from the teacher. Common choices are a lapel mic that the teacher has to wear and power-on before the lecture, a table mic or a mic array. This is a key topic in deployment. Lapel mics provide the highest quality if properly used. However up to 10% of recordings (in our estimation) are lost because of failure to power-on, incorrect placement, battery issues, etc. On the other hand, a recording with bad audio quality is useless. A conservative choice is having two sound systems (e.g. lapel and table) and use the second as a backup system. Opencast don’t provide automatic selection, so manual intervention is needed. Cameras: There are three
