Slow Motion Timing
See how long high-frame-rate footage plays when slowed to a target speed.
About Slow Motion Timing
Footage captured at high frame rate is spread over fewer playback frames per second, so the clip stretches by exactly the fps ratio. The fps ratio sets how dreamy or subtle slow motion looks, and it plans how long a short 4-5 second take actually plays.
Formula
Slow Motion Timing
Slowed duration = clip length x (recorded fps / playback fps)
- recorded fps
- Frames captured per second on set
Worked example
With the default values below, Slow Motion Timing returns Slowed Duration of 25.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Slow Motion Timing calculated?
Slowed duration = clip length x (recorded fps / playback fps) Footage captured at high frame rate is spread over fewer playback frames per second, so the clip stretches by exactly the fps ratio.
Why does Slow Motion Timing matter?
The fps ratio sets how dreamy or subtle slow motion looks, and it plans how long a short 4-5 second take actually plays.
What values do I need to enter?
This calculator takes 3 inputs: Clip length, Recorded at, Playback at. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
