Pro Tips

  • Start with lower speeds and gradually increase
  • Use 1.25x for minimal audio distortion
  • Take breaks during longer sessions
  • Adjust based on content complexity

How it works?

  • Remaining Time = (Total Time - Watched Time) ÷ Playback Speed

    Example: For a 2h video, watched 30min, at 2x speed:
    (2h - 30min = 90min) ÷ 2 = 45min remaining

  • Time Saved = (Total Time - Watched Time) - Remaining Time

    Example: From above, original remaining time is 90min:
    90min - 45min = 45min saved

  • Results are rounded to the nearest second

    Example: 1h 30min 15.7s → 1h 30min 16s
