Trampoline — pets bounce in black and white.
Trampoline turns a pet photo into grainy black-and-white footage of a backyard bounce. The sample opens on two tabby cats pressed close to the lens, looking up with wide eyes. The shot then settles on the pair sitting side by side, and soon they leap in turns, legs dangling, above the dark rim of a round trampoline.
The sample
What happens in the Trampoline sample.
The sample opens very close, with two tabby cats gazing up past the camera. In the second frame the view steadies on them sitting upright, side by side, staring straight at the lens. From the third frame on they bounce. At first both are mid-air with only their legs in view. Then one sits on the mat while the other hangs above it, paws dangling. Through the last frames they swap places again and again, and one ends up standing on its hind legs.
Every frame has a grey, grainy look with a dark vignette at the edges. Behind the trampoline the yard is dark, with a low house and bare trees against the sky. The cats keep their striped coats throughout, and the camera sits low, looking up slightly. Since the sample starts on two cats facing the camera up close, a clear shot of your pets' faces turned toward the lens is the closest match to how it begins.

Your photo
Photos that suit it.
One-tap effects have one input. The photo you pick is your creative control.
Two pets, as shown
A pair of cats takes turns in the air in the sample, so try a photo with two pets sitting side by side.
Faces toward the lens
Both cats look straight at the camera in the opening frames. A photo where your pets face the lens is the nearest match.
Think in shapes, not colour
Since the sample plays in black and white, pick a photo where the pets stand out by shape and contrast, not only by colour.

Trampoline, answered.
What does the Trampoline effect do?
Two tabby cats in grainy black-and-white footage sit side by side, then take turns bouncing high above a round trampoline in a dark backyard.
Is the Trampoline effect in colour?
Not in the sample. The clip plays in grainy black and white with dark edges and a dark sky behind. Two tabby cats first look up at the lens, then sit side by side, then take turns jumping above a round trampoline in a backyard.
How much does Trampoline 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 Trampoline 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. Trampoline is a template on the Kling engine. King AI sends the effect's name and your photo; there is no text prompt to write.
