Why Speed Up?

1.5x Speed: Ideal for slow-paced tutorials and vlogs. You save 20 minutes for every hour watched.
2.0x Speed: Best for re-watching lectures or simple content. You cut your watch time literally in half.
Audiobooks: Most people can comfortably listen to audiobooks at 1.2x - 1.5x speed without losing comprehension.

How to calculate playback speed?

The formula for calculating the new duration is simple:
Original Duration / Playback Speed = New Duration

For example, a 60-minute video watched at 1.5x speed will take 40 minutes to complete (60 / 1.5 = 40). This saves you exactly 20 minutes.

Common Speed Savings

Speed	1 Hour Video Becomes	Time Saved
1.25x	48 mins	12 mins
1.5x	40 mins	20 mins
1.75x	34 mins	26 mins
2.0x	30 mins	30 mins

Frequently Asked Questions

Does changing playback speed affect pitch?

On most modern platforms like YouTube, Netflix, and podcast players, increasing playback speed does not change the pitch. They use "time-stretching" technology to keep voices sounding natural, just faster.

Is watching at 2x speed bad for learning?

Studies suggest that comprehension remains high for speeds up to 1.5x or 1.75x, especially if you are already familiar with the topic. For complex new information, standard speed or 1.25x is recommended.
