lectureStudio vs PuMuKIT

lectureStudio is a free, open-source tool for presenting PDF-based lectures. It supports dual-screen presentations using a tablet, computer, or laptop with a projector, and presenters can mark slides with digital ink or highlights. The software records audio and video, then provides post-processing tools to correct slide errors without making a new recording. Students can participate in real-time quizzes and chat through smartphone browsers. Slides must be converted to PDF before use; the FAQ describes workflows for PowerPoint and LibreOffice Impress. Recordings can be exported as MP4 videos or lectureStudio .plr files for sharing through an LMS or file-sharing service. Institutions can host the software on-premise, and the maker says it can integrate with institution-wide Single Sign-On facilities. The maker labels lectureStudio GDPR compliant and says on-premise hosting can help address data-protection concerns tied to external services. It supports Windows, macOS, Linux, web, and self-hosted use, with live streaming listed. The project is on GitHub under GPLv3, and contributions are welcome. A FAQ and technical support contact are available.

PuMuKIT is a free, open-source video platform for organizations with large collections of video or audio. It can run a complete media site on an organization's own infrastructure, with a customizable portal for browsing by series and category. Portal widgets can surface related, most-viewed, and recently added videos. Publisher tools include drag-and-drop cataloguing, autocomplete, interactive forms, and UNESCO science and technology tags. An Opencast module supports presenting and cataloguing Opencast videos in the portal. The site describes distribution to services such as YouTube and iTunes U and learning systems including Moodle and Open edX. Organizations can provide live event channels and keep recordings available on demand. Playback supports HTML5 and Flash, with the portal described as usable in desktop browsers and on Android, iPhone, and iPad. The downloads page lists PuMuKIT 4.2.4 as the latest stable release and recommends it for production. Version 4.x is based on Symfony 5 and MongoDB. Community support is offered through mailing lists in English and Spanish. Older 1.x, 2.x, and 3.x versions are not community-supported.
