Features

Seedance v1 Lite T2V 720p — bytedance/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

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.
