Frequently Asked Questions
Will changing speed affect audio quality?
At speeds between 0.5× and 2× the audio stays clear. At 0.25× slow motion, audio can sound distorted. Remove it for the smoothest result.
How long does speed changing take?
Longer than simpler tools since every frame must be re-timed. A 2-minute video at 2× speed typically takes 30 to 60 seconds.
Can I make slow motion from a normal video?
Yes. Choose 0.5× or 0.25×. True smooth slow motion requires high frame rate source footage. Standard 30fps at 0.5× looks smooth. At 0.25× it may look slightly choppy.
What is the maximum speed I can set?
The presets go to 4×. The custom input accepts values from 0.25× to 4×.
