About This Calculator
This calculator shows how long a video will take to watch at different playback speeds. It’s useful for students, professionals, or anyone looking to save time by speeding up video content.
How It Works
Enter the video’s original duration and your desired playback speed. The calculator converts the full duration into seconds, divides it by the speed, and then converts it back to a readable format.
Actual Playback Time = (Hours × 3600 + Minutes × 60 + Seconds) ÷ Playback Speed
Frequently Asked Questions
Can I use a custom playback speed?
Yes, the calculator supports any custom speed greater than 0. Custom speed overrides any preset options.
What if I enter 0 as the speed?
The calculator will show an error since playback speed must be greater than zero.
How is time saved calculated?
Time saved is the difference between the original and adjusted durations. A shorter result means time saved.
