Why Twirl Effect Works Here
A swirl that tightens inward
The rotation grows toward the center of the lens circle, so the edges barely move while the middle winds up.
Scale stays put
Only the angle is twisted, so the swirl keeps the image's size — unlike Fisheye, which magnifies.
Motion looks hypnotic
Anything passing through the center gets pulled into the spiral.
Heavier than color filters
Twirl remaps every pixel per frame — lower Resolution on older phones.
Only on the drop
Use the Keyframe editor's time-range tool to switch Post FX to Twirl for just part of a track.
Record the swirl
Export MP4 or WebM, or save PNG stills.
Frequently Asked Questions
How do I make a video swirl?
Open the Twirl preset and load a video or choose Camera — the swirl applies to every frame.
Can I make the twirl stronger?
The twist amount is fixed; keep your subject in the center of the frame for the strongest swirl.
Can I use twirl for only part of a video?
Yes — in Clip Editor, open Keyframes and use “Set an effect for a time range” to switch Post FX to Twirl between two times.
Does it slow down on phones?
It's heavier than color filters; lowering the Resolution setting keeps it smooth.
Is it free?
Yes — free, no signup, and it runs in your browser.
