Video2Quiz

Extracts key concepts and learning objectives from uploaded video files (MP4, WebM, MOV) using speech-to-text transcription combined with NLP-based semantic analysis to automatically generate multiple-choice, true/false, and short-answer quiz questions. The system identifies salient topics through frequency analysis and contextual importance scoring, then templates these into assessment items without manual instructor input. Questions are generated with configurable difficulty levels and mapped to video timestamps for learner reference.

Automatically transcribes video audio using cloud-based speech-to-text engines (likely Whisper API or similar) with timestamp-aligned output, then indexes the transcript for full-text search and concept extraction. Supports multiple languages and handles speaker diarization to distinguish between instructor and student voices. Transcripts are stored and linked to quiz questions, enabling learners to jump to relevant video segments when reviewing incorrect answers.

Provides configurable question type templates (multiple-choice with 2-5 options, true/false, fill-in-the-blank, matching, short-answer) with adjustable difficulty levels (recall, comprehension, application, analysis). Users can specify question count, topic focus areas, and preferred question types before generation. The system applies these constraints during the NLP-based question generation phase, filtering and re-ranking candidate questions to match specified parameters.

Exports generated quizzes in multiple formats (JSON, SCORM, QTI, CSV) compatible with major learning management systems (Canvas, Blackboard, Moodle, Cornerstone, SAP SuccessFactors). Supports direct API integration for one-click import into connected LMS instances, with automatic mapping of quiz metadata (title, description, difficulty, time limit) to LMS-specific fields. Preserves video timestamp links and learner tracking data across LMS boundaries.

Tracks quiz completion rates, score distributions, time-to-completion, and question-level performance metrics (% correct per question, common wrong answers). Generates dashboards showing learner progress, knowledge gaps by topic, and comparative performance across cohorts. Analytics data is aggregated at individual, group, and organization levels with filtering by department, role, training program, or custom segments. Reports can be scheduled and exported to CSV, PDF, or pushed to external analytics platforms via webhook.

Supports video content in multiple languages (English, Spanish, French, German, Mandarin, Japanese, Korean, etc. — varies by tier) with automatic language detection and transcription in the source language. Quiz questions are generated in the same language as the video source material. Premium tiers may support quiz translation to additional languages or multilingual quiz generation (questions in one language, answers in another) for international training programs.

Provides cloud-based video upload and storage with support for multiple video formats (MP4, WebM, MOV, AVI) and file sizes up to 2GB per video on freemium tier (higher on premium). Videos are stored securely with encryption at rest and in transit. Supports batch upload for multiple videos, progress tracking, and automatic video processing (transcoding, thumbnail generation, metadata extraction). Storage quota is tiered by subscription level with options to delete or archive old videos.

Provides a web-based editor for reviewing and manually editing AI-generated quiz questions before publishing. Users can modify question text, answer options, correct answers, difficulty levels, and add explanations or hints. Supports bulk editing operations (change difficulty for multiple questions, add explanations in batch). Changes are tracked with version history, allowing rollback to previous versions. Editor includes a preview mode showing how questions will appear to learners.
