Lecture2Go vs PuMuKIT

Lecture2Go is the University of Hamburg’s web and self-hosted video portal for watching, listening to, and downloading recorded lectures. Its recording system synchronizes the speaker with the presentation. Viewers do not need accounts; login is reserved for producers. Search covers titles, series, people, keywords, and closed-caption text, with caption results linked to the matching video time. The player supports subtitles, German sign-language translations, and keyboard control, with German and English subtitles when available. Producers may enable MP4, MP4 with German Sign Language, MP3, M4A, and PDF downloads. Protected videos can use password links or embeds in university learning-management systems. Public series expose RSS feeds, and podcasts can link to Spotify, Apple Podcasts, and YouTube. Since June 2024, uploaded German and English media receive automatic subtitles using open-source solutions. The software is based on Liferay CE and includes Opencast, Subtitle2Go, Elasticsearch, and Video.js. An open-source version is available to educational institutions.

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.
