Riad, made on Leap
“One continuous gimbal move with no cuts: the camera glides forward through the carved cedar doorway into the sunlit courtyard and slowly arcs around the fountain as the rose petals settle on the water; the housekeeper looks up and smiles; light shimmers on the tiles. Sound: fountain trickle, birdsong, a distant call to prayer.”How it was made

    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, made on Leap

    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, made on Leap

    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, made on Leap

    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, made on Leap

    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.

Questions

FLUX.3 Video, answered

What is FLUX.3 Video?
FLUX.3 Video is a video model from Black Forest Labs. Black Forest Labs' first video model, from text or a first frame. 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 FLUX.3 Video start from a photo?
Yes. FLUX.3 Video starts from words or a first frame. The photo becomes the first frame, cropped to the video's shape.
How long can the videos be?
5 to 20 seconds. You choose the length before you press go, and the price follows it.
What resolution and sizes does it make?
Up to 1080p, in 21:9, 2:1, 16:9, 4:3, 1:1, 3:4 or 9:16.
Does it make sound?
Yes. FLUX.3 Video makes the sound with the picture, and it is on by default. Turn it off for a silent clip.
How is it different from FLUX.3 Video Edit?
FLUX.3 Video: Black Forest Labs' first video model, from text or a first frame. FLUX.3 Video Edit: Restyles or edits a video from a prompt at 720p, at three cents a second. They all run in the same studio, so you can try one prompt on each.
How much does a run cost?
A 5-second 720p clip costs $1.15 at the default settings. By length and resolution, a run costs $1.15 to $7.40. You see the exact price before you press go, and a run that fails costs nothing.
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.

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. Agents can call it through the MCP server at app.tryleap.ai/api/mcp.
