About Speed & Slow-Mo Calculator
Calculate video speed changes, slow-motion requirements, and resulting durations. Find the source frame rate needed for smooth slow-motion.
How It Works
Enter a duration and speed factor to see resulting playback duration, required source frame rate, and a comparison table across speed factors.
Frequently Asked Questions
What frame rate do I need for smooth slow motion?
2× slow-mo at 30fps playback needs 60fps source. 4× needs 120fps. 8× needs 240fps.
Does slow motion change resolution?
Many cameras reduce resolution at higher frame rates. Check your camera's specs for each frame rate.
