Expansion — swell up and float away.
Expansion puffs the subject up like a balloon. The sample opens on a red vintage sedan parked on a roadside at sunset, with a grey guardrail blurred in front. The car's body swells round and glossy, grows until it fills the frame, and then rises out of view.
The sample
What happens in the Expansion sample.
The sample opens on a red vintage sedan with chrome bumpers, parked on a road beside green grass and a line of trees under a sunset sky. A grey guardrail sits blurred in the foreground. The body begins to bulge and round off. Soon it is an oval red balloon with small windows and wheels pressed into its sides. It keeps swelling until it fills most of the frame, then lifts off the road and floats upward, leaving only its lower curve in view and then the empty road.
The car keeps its red paint, shine, headlights and door handles as it swells, so it stays recognisable while its shape changes. The road, grass, trees and sky stay put, and the camera holds its position. Because the subject grows much larger and then rises out of frame, a photo with space above and around the subject leaves room for the swell.

Your photo
Photos that suit it.
One-tap effects have one input. The photo you pick is your creative control.
Leave space around it
The car grows to fill the frame before rising, so a photo with open space around and above the subject leaves room for it.
Side view, whole subject
The sample starts on a side-on view of the whole car. A photo that shows your full subject is the steady choice.
Objects fit the sample
The sample uses a car, not a person, so an object photo matches what it shows.
How it works

Expansion, answered.
What does the Expansion effect do?
A red vintage sedan parked by a roadside at sunset swells into a giant glossy red balloon shape, then lifts off the road and floats up out of view.
What happens at the end of the Expansion effect?
In the sample, the red car swells into a big round balloon shape and then lifts off the road. It floats up until only its lower edge shows at the top of the frame, and after that the road, grass and trees are left empty. The sample clip carries sound, and the effect works from one photo.
How much does Expansion cost?
5–10 credits per run: 5 credits (~$2.00) at the default length and resolution, more for a longer or sharper clip (5 credits at 5s · 10 credits at 10s). New verified accounts receive 3 welcome credits once. The welcome bonus contributes toward the 5-credit first run; you need 2 more credits from a plan or credit pack.
How long is a Expansion video?
5s or 10s at 720p. It follows the shape of your photo. Nothing you export is watermarked, on any plan.
Do I need to write a prompt?
No. Expansion is a template on the Kling engine. King AI sends the effect's name and your photo; there is no text prompt to write.
