Example Calculations
| Original Time | Playback Speed | New Duration | Time Saved |
|---|---|---|---|
| 00:45:30 | 1.5x | 00:30:20 | 00:15:10 |
| 00:08:00 | 1.25x | 00:06:24 | 00:01:36 |
| 00:15:00 | 0.75x | 00:20:00 | -00:05:00 |
| 01:35:00 | 2.25x | 00:42:13 | 00:52:47 |
| 07:30:00 | 1.5x | 05:00:00 | 02:30:00 |
Math Formula
New Duration (seconds) = [(Hours × 3600) + (Minutes × 60) + Seconds] ÷ Playback Speed
Example: If you watch a 1-hour video at 1.5x speed:
3600 ÷ 1.5 = 2400 seconds = 40 minutes
