Frequently Asked Questions

What is the minimum frame rate needed to avoid choppy slow motion?

Anything below 24 FPS appears stuttery. Slowing 60 FPS down to 0.2x yields only 12 FPS. For smooth 0.2x slow-mo, record in at least 120 FPS or enable 'Optical Flow' AI interpolation in CapCut/Premiere.

How to apply a custom curve in CapCut?

In CapCut, select your clip > tap 'Speed' > tap 'Curve' > select 'Custom' and drag the bezier points to match the speed coordinates given above.
