A high school girl stands at the rooftop fence during sunset, her hair and skirt fluttering in the wind, the orange sky glowing behind her, distant voices from the courtyard below, soft anime-style shading and vivid colors enhance the emotion.

A woman in an elegant silk gown sits by a window in a classical library, turning pages of an ancient book. Outside, a fine rain falls, and the distant clock tower chimes melodically. The camera slowly zooms in from the side.

A woman turns her head in slow motion as golden leaves fall around her in an autumn park, each leaf tumbling slowly through the air, her hair moving gently, the world around her almost frozen in a moment of cinematic stillness.

A pixelated adventurer walks across a 2D medieval village at dusk, NPCs pass by in loops, flickering torches line the street, a distant mountain looms behind in low-resolution detail, the scene loops with slow ambient animations.

A woman in a light shawl stands on a rocky shore at night, gazing at the ocean under a vast starry sky, the moonlight reflecting on the waves, bioluminescent plankton glowing faintly at her feet, creating a dreamlike seascape.

An astronaut in a sleek white suit floats gently in low gravity on the surface of a distant planet, a massive ringed gas giant visible in the sky above, glowing particles drifting around him, a quiet sense of cosmic solitude.

A woman stands alone on a beach at sunrise, waves gently lapping at her feet, the sky a gradient of orange and blue, her silhouette outlined by the morning glow, seagulls flying low over the ocean in the background.

A ballet dancer rehearses alone in an empty, dusty theater, a single shaft of sunlight cutting through the window, illuminating her graceful movements as dust particles float through the air, evoking a timeless, serene beauty.

An old man walks along a dirt path surrounded by rice fields in the early morning, his shadow stretching along the path, distant mountains shrouded in mist, birds flying overhead, a sense of peace and nostalgia in the air.

A man in a vintage trench coat walks slowly through a narrow cobblestone alley in a European town, early morning fog drifting through the air, old brick buildings surrounding him, a soft golden light bathing the scene.

A streetlamp flickers on in a foggy alley. A man in a trench coat walks past, his shadow stretching against the wall. [Side tracking shot] follows him into the haze. He lights a cigarette, the flare illuminating his features briefly before vanishing into the mist.

A majestic, armored figure with a flowing cape descends from the heavens, silhouetted against a swirling galaxy of stars. Dust and cosmic energy ripple around them as they slowly land on a desolate, rocky planet. The camera dramatically tracks backward and slightly upward, revealing the vast, alien landscape stretching to the horizon, hinting at an epic journey. A powerful, soaring orchestral score with choir vocals builds to a crescendo.

A low-angle shot of a group of elegantly dressed robots performing a graceful waltz under shimmering, holographic chandeliers in a grand, art deco ballroom. Soft, warm light spills from ornate windows. The camera slowly tracks backward, revealing more of the opulent hall and other unique robotic couples dancing. A lively, electro-swing soundtrack with a whimsical feel.

Aerial shot of a serene beach at sunrise. The golden light spreads across the calm ocean waves gently lapping against the shore. A few seagulls are flying low over the water. The camera slowly pans across the horizon, capturing the vibrant colors of the sky. Gentle waves crashing sound and distant seagull calls.

A wise old owl high in the air, peeking through the clouds in a moonlit sky above a forest. The wise old owl carefully circles a clearing looking around to the forest floor. After a few moments, it dives down to a moonlit path and sits next to a nervous badger. The owl hoots thoughtfully, and the badger makes nervous chitters. The camera follows the owl's flight and then slowly zooms in on the two animals. A light orchestral score with woodwinds throughout, full of innocent curiosity.

A lone astronaut walks across a desert made of glass. The sky above shimmers with auroras. Each step crunches like crystal. [Wide shot] reveals monolithic alien structures buried in the sand.

A detective walks into a noir-style diner, rain dripping from his coat. Neon signs flicker outside the window. [Over-the-shoulder shot] as he sits across from a woman in red, her eyes hidden behind dark glasses.

A child opens a mysterious glowing book in a dark attic. Golden light spills onto his amazed face. Floating letters swirl into the air, forming a portal. [Tilt-up shot] follows the magic lifting him gently off the floor.

A young couple rides a motorbike along a winding coastal road. The camera alternates between a side pan and a drone shot trailing behind them. Ocean sparkles on one side, cliffs blur past on the other.

An old man with white hair walks barefoot into a warm river at sunrise. The water glows orange as ripples form around him. The camera pans slowly from behind, revealing him stepping deeper into the golden mist.

Seedance v1 Lite T2V 720p — /seedance-v1-lite-t2v-720p

Seedance v1 Lite T2V 720p generates short videos directly from a text prompt. Describe the subject, action, scene, and camera intent, and the model produces a coherent 720p clip with smooth motion—great for story beats, anime-style moments, quick pre-visualization, and rapid creative iteration. You can optionally enable camera_fixed to keep framing steady while motion happens within the scene.

Key capabilities

  • Text-to-video generation (720p) optimized for fast iteration
  • Good motion from clear action verbs and scene direction
  • Optional camera_fixed mode for stable framing (no camera movement)
  • Supports multiple aspect ratios for common layouts (e.g., 16:9)

Use cases

  • Short story moments and animated shots (5–20s beats)
  • Anime-style scene generation with expressive lighting and motion
  • Quick pre-vis for camera blocking and action timing
  • Social-ready clips and concept trailers at lightweight cost
  • Creating variations by changing seed while keeping the same prompt

Pricing

DurationPrice per video
5s$0.16
10s$0.32
15s$0.48
20s$0.64

Parameters

  • prompt (required): Describe what happens in the video (subject, action, scene, mood)
  • aspect_ratio: Output aspect ratio (e.g., 16:9, 9:16, 1:1)
  • duration (required): Video length in seconds
  • camera_fixed: Whether to fix the camera position
  • seed: Random seed (-1 for random; fixed value for reproducible results)

Prompting guide (T2V)

Write prompts like a director’s brief:

  • Subject: who/what is on screen
  • Action: what changes over time (fluttering, turning, walking, reacting)
  • Scene: where it happens + time of day
  • Lighting: sunset glow, neon, soft volumetrics, etc.
  • Camera: only describe movement if camera_fixed is off

Example pattern: A [subject] [action] in [scene], [lighting], [mood], smooth motion, cinematic pacing.

Example prompts

  • A high school girl stands at a rooftop fence during sunset, hair and skirt fluttering in the wind, orange sky glowing behind her, distant courtyard ambience, soft anime-style shading, vivid colors, gentle camera drift.
  • Close-up of a musician’s hands playing guitar, warm indoor lighting, shallow depth of field, subtle handheld motion, realistic details.
  • A sci-fi corridor scene with drifting fog and blinking lights, a character slowly turns toward the camera, dramatic rim light, cinematic tension.
