Soba under the tracks, made on Leap
“He slurps a big mouthful of noodles, steam curling up into the bulb light, then exhales and closes his eyes for a second. A train thunders across the tracks overhead, the bulb sways and flickers, fine dust drifts down. The young cook behind him stirs the stock pot. Slow handheld push-in with a slight natural sway. Sound: heavy train rumble overhead, slurping, broth bubbling, rain outside. No music.”How it was made

    Pav bhaji at midnight

    He presses the iron masher down and smashes the melting block of butter into the bubbling bhaji with fast, hard strokes; the butter spreads and sizzles, steam bursts up into the bulbs; a customer's hand at the left holds out a steel plate. Close handheld camera, slow push-in, slight shake. Sound: loud sizzle, iron clanging on the tawa, crowd chatter, distant traffic. No music.

  • Four on a scooter, made on Leap

    Four on a scooter

    The family rides through the monsoon downpour alongside the camera; the father keeps the tower of red plastic stools perfectly balanced on his shoulder without looking, the boy hugs the goose, which honks and flaps one wing, and the boy shushes it; headlights streak past on the wet road. Camera tracks alongside at the same speed with a gentle bob. One continuous shot, no cuts. Sound: heavy rain, scooter engines, a goose honking, horns. No text, no logos, no labels, nothing printed anywhere.

  • Çay, made on Leap

    Çay

    Holding eye contact with the camera, the cat slowly pushes the tulip glass of tea along the marble sill with one paw until it tips over the edge and falls out of frame; the man's hand grabs at it a moment too late. The cat keeps staring at the lens, then calmly pushes the sugar cube off the edge too. Static camera. One continuous shot, no cuts. Sound: a ferry horn far away, the glass shattering below, an old man groaning. No text, no logos, no labels, nothing printed anywhere.

  • Oi, made on Leap

    Oi

    The gull snatches the chip right out of the man's fingers an inch from his mouth and wheels away over the sea; he freezes with his mouth still open, then turns and shouts after it, shaking his fist. Handheld camera. Sound: wind, gulls screaming, the man shouting 'Oi!', waves.

  • KOLO, shot 2, made on Leap

    KOLO, shot 2

    Her thumbs pump the plunger and a thick stream of espresso with golden crema pours into the clear cup, the crema swirling. Close, static. Sound: pump clicks, espresso dripping.

  • KOLO, shot 1, made on Leap

    KOLO, shot 1

    She talks fast and excited to the camera: "Okay. Night shift survival kit. This is a tiny espresso maker and you literally just pump it." She pumps the plunger a few times with her thumb and laughs. Handheld selfie wobble. Sound: room tone and her voice only. No music.

  • Gol, made on Leap

    Gol

    The goal goes in: she screams and leaps up, beer foam flying out of her glass, and grabs the stranger next to her in a hug; the whole bar erupts and the old man throws his cap in the air. Handheld camera jostled by the crowd. Sound: a huge roar, her scream of 'GOOOL', glasses clinking, a TV commentator yelling.

  • Northbound, shot 5, made on Leap

    Northbound, shot 5

    The violet light pulses brighter on her face; her eyes widen and her breath catches; the light cuts out and she is in darkness for a beat, then it flares again. Static camera. Sound: a deep hum rising, her breath.

  • MIRRA, shot 2, made on Leap

    MIRRA, shot 2

    She turns her head slowly from profile into the hard key light and opens her eyes to the lens with a calm, knowing look; the silk collar shifts. Static camera. Sound: low sub bass, a breath.

Questions

Seedance 1.5 Pro, answered

What is Seedance 1.5 Pro?
Seedance 1.5 Pro is a video model from ByteDance. Sharp, steady video at a very low price, with optional sound. On Leap it runs in one studio beside every other top model, with one account.
Can Seedance 1.5 Pro start from a photo?
Yes. Seedance 1.5 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?
5 or 10 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 16:9 or 9:16.
Does it make sound?
Yes, when you turn sound on. Leave it off for a silent clip.
How is it different from Seedance 2.5, Seedance 2.0 and Seedance 2.0 Fast?
Seedance 1.5 Pro: Sharp, steady video at a very low price, with optional sound. Seedance 2.5: Lifelike motion with sound made in the same take, from text, a first frame with no real person in it, or up to 30 images, 10 videos and 10 sounds it follows. Seedance 2.0: ByteDance's reliable all-rounder: lifelike motion with sound, from text or a first frame with no real person in it. Seedance 2.0 Fast: Seedance 2.0, faster and for less, up to 720p: quick takes with sound, from text or a first frame with no real person in it. 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 without sound costs $0.175 at the default settings. By length, resolution and sound, a run costs $0.0875 to $1.60. You see the exact price before you press go, and a run that fails costs nothing.
Is Seedance 1.5 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 $0.0875 (a 5-second 480p clip without sound), so $5 covers 57 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 bytedance/seedance-1.5-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 ByteDance account?
No. Leap sends your request to ByteDance's model and gives you what it makes. One Leap account runs Seedance 1.5 Pro and every other model, in the studio, through the API and from your agents.

Your idea, Seedance 1.5 Pro.

Every run shows its price before it starts, and one that fails costs nothing.
