# Active Recall: How Video Revision Works

Passive watching is one of the biggest illusions of competence in online
learning. You can watch an entire two-hour video lecture and feel like you
understand the subject, but forget 80% of it within 48 hours. Quietube
integrates Active Recall directly into your study flow to convert short-term
visual exposure into long-term retention.


THE SCIENCE OF ACTIVE RECALL

Active recall forces your brain to retrieve information from memory rather than
simply recognizing it when shown. Quietube's revision engine automates this
process:

 * Transcript Intelligence: Quietube extracts key propositions, formulas,
   definitions, and conclusions from the lecture video transcript.
 * Automated Assessment Generation: When a lecture finishes (or whenever you tap
   Revise Video), Quietube automatically generates a customized set of retention
   questions.
 * Immediate Feedback Loop: Review your answers with detailed explanations and
   see which timestamps in the video explain the correct reasoning.


STARTING A VIDEO REVISION SESSION

 1. While or after watching any lecture, tap the Revision / Quiz tab beneath the
    player.
 2. Tap Start Quick Revision.
 3. Choose how many questions you want to tackle (e.g., 5 quick questions or 10
    deep review items).
 4. Complete the practice round to earn XP points and solidify your mastery.


REVISION HISTORY & WEAK AREA TRACKING

Your revision performance is stored under your account. If you score below 70%
on a specific topic, Quietube flags it in your study insights, recommending a
quick re-watch of the relevant timestamped chapter before your exams.
