MIRRA, shot 4
She presses the brass cap and a fine golden mist bursts into the backlight; she brings her wrist to her face, closes her eyes and breaks into a laugh. Static camera. Sound: the spray hiss, her laugh.

Teta's cake
Trick candles. The boy blows hard and all five candles go out; a beat later they relight by themselves, one by one. He blows again, puffing his cheeks, and they relight again. His grandmother sighs, licks two fingers and pinches every flame out, deadpan, one by one, while the relatives behind them cheer and film on their phones. Handheld, slight shake. One continuous shot, no cuts. Sound: blowing, the fizz of trick candles relighting, laughter, cheering. No text, no logos, no labels, nothing printed anywhere.

Slush
Ground-level macro on the plain cobalt-and-white sneakers, which stay on his own two feet the whole time: his right foot stomps straight into the slush puddle on purpose, icy water explodes up and out, and he crosses the ball over and drives away from the camera through the spray, both feet in the same plain cobalt sneakers, while a train roars across the tracks overhead. The shoes have no logo or mark anywhere. One continuous shot, no cuts. Sound: the slap of the stomp, the splash, the ball bouncing, a train roaring overhead. No text, no logos, no labels, nothing printed anywhere.

The keeper
Stylized 3D animation. Lightning cracks outside; the tiny keeper shrieks, wobbles on her stool and grabs the giant brass lens, which starts to turn with her clinging to it, carrying her all the way round once like a fairground ride while its beam sweeps across the stormy sea; she lands back on the stool, glasses askew, and keeps polishing. One continuous shot, no cuts. Sound: thunder, rain on glass, the clank of the lens mechanism, a squeak. No text, no logos, no labels, nothing printed anywhere.

Northbound, shot 1
Locked-off wide shot. A blinding electric-violet meteor rips across the whole sky from left to right in under one second and is gone behind the hills; a violet flash lights the horizon; two seconds later a deep boom rolls across the steppe, the horses toss their heads and bolt a few steps, and the ger door swings open, spilling warm light. One continuous shot, no cuts. Sound: wind, silence, then a deep rolling boom and whinnying. No text, no logos, no labels, nothing printed anywhere.

Northbound, shot 2
He lowers the binoculars slowly, his face going still with fear, and turns to call back into the ger. Breath steams. Slow push-in. Sound: wind, the stove crackling, his voice calling a name.

5 da manhã, shot 2
Rapid Afro-house footwork: heel-toe shuffles, a quick kick and a slide across the mosaic stones, water flicking from the puddle. Camera on the ground, static.

Rooftop legwork
He breaks into fast Afrobeats legwork, feet shuffling and kicking in a quick rhythm, shoulders bouncing, then freezes and points straight at the camera with a huge gap-toothed grin. The schoolgirls behind him burst out laughing and clap. The handheld camera circles slightly to the left. Dust kicks up from the roof in the dusk light. Sound: an Afrobeats song playing from a phone speaker, the girls laughing and clapping, city noise below.

Cormorant
Ink-wash 2D animation: the fisherman pushes the raft forward with his pole and ripples spread as brush strokes; one cormorant dives and surfaces with a silver fish; mist drifts across the peaks; the lantern sways. Painted, hand-drawn motion. Sound: water lapping, a cormorant's call, a distant guqin.

Questions
Kling O3 Pro, answered
- What is Kling O3 Pro?
- Kling O3 Pro is a video model from Kuaishou. Animates a first frame, to an optional last frame, with optional sound. It is new on Leap and in preview: it works, and it may still change. On Leap it runs in one studio beside every other top model, with one account.
- Can Kling O3 Pro start from a photo?
- Yes. Kling O3 Pro starts from words, a first frame or a last frame. The photo becomes the first frame, cropped to the video's shape.
- How long can the videos be?
- 3 to 15 seconds. You choose the length before you press go, and the price follows it.
- Does it make sound?
- Yes, when you turn sound on. Leave it off for a silent clip.
- How is it different from Kling 3.0, Kling 2.6 and Kling 3.0 Motion Control?
- Kling O3 Pro: Animates a first frame, to an optional last frame, with optional sound. Kling 3.0: Cinematic motion and strong physics, from text or a first frame. Kling 2.6: Kling's value model: smooth motion at a low price. Kling 3.0 Motion Control: Moves the character in your image the way the person in a reference video moves, and keeps the face through turns, hands and hats. Billed by the length of the reference video. They all run in the same studio, so you can try one prompt on each.
- How much does a run cost?
- A 5-second clip without sound costs $0.75 at the default settings. By length and sound, a run costs $0.45 to $2.775. You see the exact price before you press go, and a run that fails costs nothing.
- Is Kling O3 Pro free to try?
- No. There is no free credit: you add credit from $5, and your first top-up has no card fee. The cheapest run is $0.45 (a 3-second clip without sound), so $5 covers 11 of those. You pay per run, in dollars, with no subscription.
- Can I use what I make commercially?
- Yes. You own what you make on Leap, so you can use it commercially, and we never train AI on it. The people and brands shown in a result can still have rights in it; the Terms say more.
- Is there an API?
- Yes. Leap's REST API runs it as kling/kling-o3-pro, at the same price per run as the studio, and agents can call it through Leap's MCP server. The request is at the bottom of this page.
- Do I need a Kuaishou account?
- No. Leap sends your request to Kuaishou's model and gives you what it makes. One Leap account runs Kling O3 Pro and every other model, in the studio, through the API and from your agents.
Your idea, Kling O3 Pro.
Every run shows its price before it starts, and one that fails costs nothing.

The request
The same envelope for every model; only the model and its input change. With prefer: wait=60 the answer holds the result when the run finishes within a minute; a longer one is read again by its ID. A file input takes the ID that POST /v1/files returns for your upload. Agents can call it through the MCP server at app.tryleap.ai/api/mcp.
