Video Summarization & AI Quiz Generation: Kaltura

Kaltura automates the organisation of lecture core content and generates interactive quizzes, saving you time on post-class preparation while significantly enhancing students’ pre-class readiness and review efficiency.

1. About Kaltura: Your On-Campus Video Teaching Assistant

Kaltura is a customised video teaching tool for academic staff at our university, designed to solve two key teaching challenges:

The time-consuming effort of manually organising lecture highlights and notes post-class.
Students’ lack of targeted guidance during review, makes it hard for them to focus on core knowledge.

By leveraging AI to transform standard lecture videos into "extractable, interactive, and trackable" learning resources, Kaltura delivers dual value: reducing staff workload and improving student learning outcomes.

2. Core Features: Save Time, Enhance Student Learning

A. Automated Lecture Video Summarisation – Cut 60% of Manual Work

No more spending hours sorting through video frames to compile notes or clip highlights—AI handles this for you:

Precise Core Knowledge Extraction: Automatically identifies key concepts, formulas, and case studies (e.g., "GDP calculation logic in macroeconomics," "critical steps in chemistry experiments") from videos, with timestamps linked to each point. Students can click on highlights to jump directly to the corresponding video segment, eliminating the need to scroll through entire videos.
On-Campus Adapted Export Formats: Export summaries as ① downloadable text outlines for students, ② timestamped notes embedded in course slides, or ③ 5-minute highlight clips—all tailored to pre-class preparation, in-class supplements, and post-class review.
1-Minute Lightweight Editing: AI-generated summaries can be edited online (e.g., adding ad-hoc explanations from class) without re-uploading or reprocessing the entire video.

B. AI-Powered Quiz Generation – No Professional Skills Required

Skip the 1–2 hours spent designing review questions—quizzes are auto-generated based on lecture highlights, with real-time tracking of student mastery:

Knowledge Point Alignment: Generated quizzes strictly correspond to core content in video summaries (e.g., if 3 research methods are highlighted, multiple-choice questions distinguishing these methods will be created). You can also add custom subjective questions or case-based prompts specific to your course.
Multi-Scenario Question Types: Supports multiple-choice, true/false, fill-in-the-blank, and "video hotspot questions" (e.g., asking students to click on a lab equipment diagram in the video). Use "basic recall questions" for pre-class prep and "application questions" for post-class assessment.
Seamless LMS Sync: Quizzes can be synced to your course LMS with one click. After students complete them, the system auto-grades responses and generates reports (e.g., "80% of students did not master ‘lab safety protocols’"), helping you quickly identify topics needing review.

3. How to Use Kaltura (3-Step On-Campus Workflow)

The process is optimised for our university’s systems and takes only 5–10 minutes to complete:

Upload Your Video (1 Minute)
Log in to the on-campus Kaltura platform (access directly from the "Course Tools" tab in your LMS course page). Click "Upload Media" and select your lecture video (supports MP4, MOV, AVI—no compression needed, even for large files).
Set Your Preferences (2 Minutes)
1. Generate a summary: After upload, click "AI Tools" → “Generate Summary.” Select your subject type (e.g., "STEM – Prioritise Formulas & Cases," "Humanities – Prioritise Theories & Arguments"). The system will finish extraction within 5 minutes.
2. Generate a quiz: Click "Interactive Video" → "Add Quiz." Choose question types (mixable), question count (5–10 recommended), and the system will auto-link questions to knowledge points in the summary.
Share with Students (1 Minute): Preview and fine-tune the summary/quiz, then click “Publish to LMS.” Select your course section and set access permissions (e.g., "Visible to enrolled students only"). Students will find the video, summary, and quiz in the "Course Resources" tab of their LMS.

4. Practical Tips

Based on feedback from fellow university instructors, Kaltura works best in these three scenarios:

Pre-Class Preparation: Share the "summary + basic recall quiz" 1 day in advance. Students arrive with foundational knowledge of core concepts, allowing more in-class time for case discussions or group work (reducing one-way lecturing).
Post-Class Review: Upload the full lecture video + "application-based quiz." Students receive instant feedback on which knowledge points they missed and can revisit the corresponding video segments. You can use quiz reports to target review of unclear topics in the next class.
Cross-Semester Reuse: Save summaries and quizzes to your "My Library." For future semesters, simply replace the video (if content updates) and reuse existing resources—eliminating repetitive work.
