Playback Speed Calculator
Playback speed calculator is a decent utility to handle playback calculations and gives you an idea of how much can you save to listen an audio or video at different playback speeds.
Just fill in the simple input click on the calculate button and let the playback speed calculator brew its magic.
Input Required in Playback Speed Calculator
Manually enter the original time of an audio or video typically in hours, minutes, and seconds (HH:MM:S). Set desired playback speed from 0.25x, 0.5x, 0.75. 1.0x, 1.25x, 1.5x, 1.75x, to 2.0x. Click on the calculate button and get the results. The result field displays the calculated time which typically takes you to watch a video and the time you would potentially save for different playback speeds.
Math Behind Video Speed Control Calculator
It is a kind of Video speed adjustment tool that adjusts playback speed online using simple mathematical logic:
Adjusted Time = Original Time / Playback Speed
Original Time: The total time duration of an audio or a video in hours, minutes, and seconds
Playback Speed: it is the speed at which the media is being played back, relative to its original speed.
Adjusted Time: is a time calculated with the playback speed calculator at different playback speed settings
Let’s say a video of 133 minutes played at 1.5x speed. The adjusted time will be:
Adjusted time = 133/1.5 = 88.66
Whereas the time saved with the playback speed calculator would be:
Time saved = Original time – adjusted time
Time saved = 133 minutes – 80 minutes = 44.33 minutes
This formula is often used in playback speed calculators to quickly determine how long it will take to watch or listen to media at different speeds.
What Playback Speed Duration Converter Tool Do
It converts all input durations into seconds first and then divides it with the playback speeds to precisely calculate the adjusted time and time saved.
For example let’s calculate a video playback speed of a 1 hour, 30 minutes, and 45 seconds at 1.5s playback setting:
Original time T = (1 x 3600) + (30 x 60) + 45
T = 3600 + 1800 + 45 = 5445 seconds
Applying calculator for playback speed formula:
Adjusted Time = 5445 / 1.5x = 3,630 seconds
So, the adjusted time is 3630 seconds. Let’s convert them to hours, minutes, and seconds
3630÷3600=1 hour (remaining seconds: 3630−3600=30 seconds)
As there is no remaining full minute so minutes are 0
The adjusted time would be 1 hour, 0 minutes, and 30 seconds.
Example Table Playback Speed Calculation
Here is the table of playback runtime calculations at different playback speeds of a video having the original time of 3 hours, 45 minutes, and 9 seconds:
| Original Time (Input) | Playback Speed (Input) | Adjusted Time (Result) | Time Saved (Result) |
| 3h 45m 9s | 1x | 3h 45m 8s | 0h 0m 0s |
| – | 0.25x | 3h 0m 7s | 0h 45m 1s |
| – | 2x | 1h 52m 34s | 1h 52m 34s |
| – | 1.5x | 2h 30m 5s | 1h 15m 3s |
| – | 1.75x | 2h 8m 39s | 1h 36m 29s |
Final Take
Altering playback speed would give you an estimate of how much time you will save watching a video at different speeds. Additionally, it also enhances your listing experience. For example, if you only want to get an idea about what content would be in a video then adjusting higher playback speeds would be useful to save time for other stuff. This calculator is designed based on the logic to give precise information.
