# Video Chapters, Timestamps and Timestamped Notes

Long educational lectures often run for two to three hours. Finding the exact
theorem, problem explanation, or derivation shouldn't require manual guessing.
Quietube solves this with automated chapter parsing and synchronized timestamped
notes.


AUTOMATIC VIDEO CHAPTERS

Quietube's timeline engine automatically extracts video chapter markers and
timestamps from the lecture:

 * Interactive Chapter List: Tap the Chapters button below the player to view
   the complete topic outline with start times and topic titles.
 * One-Tap Seek: Tap any chapter in the outline to instantly jump the video
   player to that specific concept.
 * Active Chapter Indicator: The seekbar visually highlights the chapter you are
   currently watching so you always know where you are in the lecture.


TIMESTAMPED VIDEO NOTES

Taking notes while watching a lecture in Quietube automatically binds each
thought to the exact second in the video:

 1. While watching a lecture, tap the Notes tab directly beneath the video
    player.
 2. Tap Add Note. Quietube automatically pre-fills your current playback
    timestamp (e.g., 14:32).
 3. Type your takeaway, formula summary, or reminder and tap Save.

Your notes are stored securely under your private study profile. When you review
your notes days or weeks later, tapping the timestamp badge instantly opens the
video and jumps directly to that second!
