lectureStudio vs Viz CaptureCast

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.

Viz CaptureCast is an on-premise, network-based appliance for capturing, composing, streaming and publishing classrooms, meeting rooms and events. It automates recording, live streaming and publishing, including scheduled workflows. Across concurrent room workflows, it can record up to six NDI or NDI|HX inputs, with recording and streaming described at up to 1080/30p. During lectures, it captures presentation slides and text for searchable video and enriched playback. A browser interface and CaptureCast Workflow Wizards configure, manage and control spaces and workflows. Vizrt lists integrations with Kaltura, Panopto and Opencast, and streaming to Vimeo and YouTube. NDI can connect directly with Microsoft Teams and Zoom. Optional CaptureCast Spaces subscriptions start with one space workflow and scale to three concurrent workflows. Vizrt describes the product for educators and corporate teams. It supports Windows, searchable transcripts, multi-camera capture, live streaming, camera tracking, LED-stage, greenscreen and live-compositing workflows.
