MIRRA, shot 1
The drop slides down the facet and falls; the amber caustics shift as the light slowly sweeps across the bottle; the camera creeps closer in a slow macro push. Sound: a single deep piano note, a soft drip.

5 da manhã, shot 4
He breaks the freeze into a fluid wave through his arms and body as the sun touches the river behind him; pigeons lift off the balustrade. Slow dolly around him. Sound: pigeons, distant city waking.

Lilac
The model strides up the ramp toward the camera, then pivots sharply on one heel and turns away, the oversized lilac jacket flaring wide; dust lifts off the concrete in the sun shaft. The camera dollies backward fast at low height, then whips a quick pan to follow the turn. Editorial fashion film, confident and deliberate. Sound: footsteps echoing on concrete, fabric snapping, a low synth bass pulse.

Northbound, shot 6
The horses gallop through the frame kicking up snow as the violet column behind the ger brightens and lights the whole steppe like day for a moment, then goes dark. Static camera. Sound: thundering hooves, a rising tone, then silence.

Minuterie
Horror film shot, vertical, looking straight up the spiral stairwell of an old Paris apartment building at night from the ground floor: worn wooden steps, a black wrought-iron banister curling upward, cracked cream plaster. The timed hallway light clicks off and the stairwell drops into darkness; when the yellow bulbs flicker back on, a tall thin figure in a long black coat is standing motionless on the third-floor landing, leaning over the banister, looking down. Static camera, 35mm grain, deep shadows. Sound: the click of a light switch, buzzing bulbs, a creaking floorboard.

- Is FLUX.3 Video 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 $1.15 (a 5-second 720p clip), so $5 covers four 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 black-forest-labs/flux-3-video, 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 Black Forest Labs account?
- No. Leap sends your request to Black Forest Labs' model and gives you what it makes. One Leap account runs FLUX.3 Video and every other model, in the studio, through the API and from your agents.
Your idea, FLUX.3 Video.
Every run shows its price before it starts, and one that fails costs nothing.
