ByteDance video model with sound and dialogue
Seedance 1.5 Pro AI Video Generator
Seedance 1.5 Pro makes the picture and the sound in one pass, and it speaks the line you write in quotes, in English or Spanish, with the lips moving to the words.
Seedance 1.5 Pro is ByteDance's AI video generator. On Pixel Dojo it turns a text prompt or a start image into a clip of 4 to 12 s at 480p or 720p, in six aspect ratios from 21:9 to 9:16, with its own sound track. We made every clip on this page on Pixel Dojo: a 10 s ultra-wide biplane flight over a fjord, a snowy platform close-up that speaks English, a cafe scene in Spanish, a vertical rooftop dance, a stop motion fox baker and a fiery lion reveal. Pick one and start from its prompt.
8 credits ($0.50) per 5 s clip at 720p with audio. Included in every plan, from $10/month.

What Seedance 1.5 Pro does best
Dialogue in English and Spanish
Write a line in quotes and Seedance 1.5 Pro speaks it, with the lips moving to the words. We quoted one English line for a woman on a snowy train platform and one Spanish line for a man at a cafe table, and both come through word for word: "I waited for the last train" and "Siempre vuelves en otoño". Faces and wardrobe hold steady for the whole clip.
Sound made with the picture
Every clip on this page has its own sound track, generated in the same pass as the video. End your prompt with the sounds you want, like a buzzing engine, rushing wind or a cafe murmur, as our prompts do.
Sweeping single takes up to 12 s
Our 10 s biplane flight follows the red biplane in one unbroken shot as the camera swings from its side to its tail over the fjord, and the 21:9 frame gives it a widescreen trailer look.
Flowing fabric and fashion
Give the garment one clear move. Our vertical rooftop dancer spins once in a crimson silk slip dress, and the silk flares and settles through the full turn with the city skyline glowing behind her.
Stop motion style animation
Ask for claymation and lock the camera. Our fox baker comes out warm and handmade, with oven glow, curling steam and a fox that lifts the tray like a real little baker.
Fiery VFX reveals
Describe the before and the after in one sentence. Our temple steps prompt opens on a shell glowing with molten cracks that bursts into embers as a bronze lion steps out in front of a column of flame, all in 4 s.
What you can create with Seedance 1.5 Pro
We made each of these on Pixel Dojo from a single text prompt, at 720p with sound on, and every tile shows the exact prompt and settings. Tap Use this prompt on any clip to start from it.
An aerial chase in ultra-wide 21:9, one 10 s shot for 15 credits. The red biplane skims the teal fjord trailing a white wake of mist while the camera swings from its side to its tail, waterfalls pouring off green cliffs toward a hazy sunrise, all with its own sound track. Start from this prompt for travel and adventure openers.
Ultra-wide aerial tracking shot: a red vintage biplane skims low over a glassy turquoise fjord at sunrise, its propeller wash tearing a trail through the morning mist on the water, sheer green cliffs and white waterfalls on both sides, the camera banking with it. Anamorphic lens, warm gold sun flare, teal water, crisp documentary clarity. Sound: a buzzing radial engine, rushing wind, a distant waterfall roar.
A VFX reveal in one 4 s clip for 6 credits. A stone shell glowing with molten cracks bursts apart in a shower of embers, and a bronze lion with glowing eyes steps out onto the temple steps in front of a column of flame. Start from this prompt for fantasy trailers and title reveals.
Slow push-in, low angle: a weathered bronze lion statue on ancient temple steps at dusk cracks open, molten golden light spilling through the seams as bronze flakes peel away into drifting embers, revealing a lion made of living fire that lifts its head and shakes a blazing mane. Deep blue dusk sky, warm firelight on the stone, 35mm anamorphic lens, cinematic contrast. Sound: cracking metal, a deep rumbling roar, the whoosh of flames.
Fashion in vertical 9:16 for 6 credits. She spins a full circle on a sunlit rooftop and the crimson silk flares wide and settles as she turns, with a hazy city skyline behind her. Built for reels and stories.
Vertical full shot, slow push-in: a dancer in her thirties with a sleek black bob and small gold hoop earrings spins once in a flowing crimson silk slip dress on a sun-bleached rooftop at golden hour, the hem flaring out and rippling in the wind, a hazy city skyline behind her. Warm low sun backlighting the silk, 35mm lens, fine film grain. Sound of wind gusts and rustling fabric.
A speaking close-up, 5 s for 8 credits. Snow falls past the platform lamp as she turns to the camera and says "I waited for the last train", her lips moving with every word. Put the line in quotes, as this prompt does, and Seedance 1.5 Pro voices it.
Close-up, slow push-in through falling snow at night: a woman in her fifties with a cropped silver haircut and a mustard wool scarf stands under a flickering train platform lamp, snowflakes catching in her eyelashes, and she says softly, "I waited for the last train." Warm sodium light on her face, cold blue night behind her, 85mm lens, shallow depth of field, fine film grain. Sound: a distant train horn, wind, crunching snow.
Stop motion style animation with a locked camera, 6 credits. A round orange fox in a flour dusted apron pulls a tray of golden rolls from a glowing brick oven as steam curls up, with a handmade stutter to the motion. Start from this prompt for cozy animated shorts.
Stop-motion claymation style, medium shot, camera still: a round orange clay fox in a flour-dusted blue apron pulls a tray of golden bread rolls out of a glowing brick oven in a tiny cozy bakery, a puff of steam rising from the bread, thumbprint textures on the clay and a slight stop-motion stutter. Warm oven light, felt and wood props. Sound of a crackling oven and a cheerful little hum.
Dialogue in Spanish, 4 s for 6 credits. A white bearded man in a felt hat looks up from his coffee in an old town square and says "Siempre vuelves en otoño" with a warm smile, a church spire and a yellow autumn tree behind him. Write the line in Spanish, as this prompt does, and he speaks it in Spanish.
Close-up, slow push-in: a man in his sixties with a trimmed white beard, a flat cap and a navy wool coat sits at a cafe table in a sunlit old town square, looks up from his coffee and says warmly in Spanish, "Siempre vuelves en otoño." Golden late afternoon light, autumn leaves drifting behind him, 50mm lens, soft film grain. Cafe murmur and distant church bells.
How to get Seedance 1.5 Pro clips like these
Pick any length from 4 to 12 s and pay only for the seconds you use. Here is our biplane prompt as a 4 s clip for 6 credits, the same prompt as the 10 s hero, followed by the tips behind every example on this page.
The biplane prompt at 4 s, for 6 credits. The red biplane skims the turquoise fjord past tall waterfalls, a white trail of mist streaming across the water behind it.
Ultra-wide aerial tracking shot: a red vintage biplane skims low over a glassy turquoise fjord at sunrise, its propeller wash tearing a trail through the morning mist on the water, sheer green cliffs and white waterfalls on both sides, the camera banking with it. Anamorphic lens, warm gold sun flare, teal water, crisp documentary clarity. Sound: a buzzing radial engine, rushing wind, a distant waterfall roar.
- Write prompts like a shot note: shot size and camera move first, then a specific subject, one action, light, lens and the sounds you want. Every prompt on this page follows that order.
- Put spoken lines in quotes and say how they are delivered, like "says softly" or "says warmly in Spanish", as our platform and cafe prompts do.
- Give each clip one clear action. A single spin, one pull from the oven or one burst of embers reads cleanly from start to finish.
- Turn on camera fixed for tabletop and stop motion looks, as our clay fox baker does, and leave it off for tracking shots like the biplane flight.
- Pick 21:9 for widescreen trailers, 9:16 for reels and stories, and 16:9, 4:3, 1:1 or 3:4 for everything in between.
- Render at 720p. It costs the same as 480p, and every clip on this page is 720p.
- Start from an image when you need a specific look. Seedance 1.5 Pro takes a start image, plus an optional end image, and builds the motion between them.
Seedance 1.5 Pro vs WAN 2.7 at the blacksmith's anvil
We gave Seedance 1.5 Pro and WAN 2.7 the same blacksmith prompt, both 5 s at 720p. Seedance 1.5 Pro throws big showers of sparks across the forge on the hammer blows and keeps the smith's firelit face in frame for the strikes, with its sound track made in the same pass. WAN 2.7 frames the apron, tongs and anvil, with orange hot steel and a big cloud of steam on the quench. For strikes, sparks and a character you can see, we reach for Seedance 1.5 Pro, and at 8 credits it cost less for this clip.
Same prompt: Medium shot, slow push-in: a bearded blacksmith in a heavy leather apron over a gray linen shirt with rolled sleeves strikes a glowing orange horseshoe held in tongs on the anvil, each hammer blow throwing a shower of bright sparks across the dark stone forge, then he plunges it into a water trough in a burst of hissing steam. Firelight from below, 35mm lens, deep shadows, gritty film grain. Sound: ringing hammer strikes, crackling coals, a loud steam hiss.
Seedance 1.5 Pro, 5 s for 8 credits: sparks shower across the dark forge on the strikes, and the smith's face is lit by the fire as he works.
