Vidu Text To Video 2.0 API Documentation
Playground
Try it on WaveSpeedAI!Vidu Text-to-Video 2.0 converts text prompts into high-quality 720p videos with exceptional visual detail and diverse motion dynamics. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.
Features
Vidu Text-to-Video 2.0 turns your imagination into motion — a next-generation text-to-video model that produces cinematic 720p videos with smooth, expressive, and visually coherent motion. Now with flexible duration control, you can generate 5s or 8s clips for storytelling, concept visualization, or creative motion studies.
🌟 Why it looks amazing
- Cinematic realism: generates film-like motion, lighting, and depth of field.
- Temporal consistency: prevents flicker and ghosting between frames.
- Expressive movement: animates both camera and subject naturally for lifelike motion.
- Scene understanding: interprets your text prompt accurately to match composition, emotion, and action.
- 720p output: crisp visuals ready for editing, sharing, or production use.
⚙️ Parameters and Controls
-
prompt — describe your scene (e.g., “A woman walking through a rainy street under neon lights”).
-
auto(default): automatically adjusts motion scale. -
small: subtle, gentle movements (good for portraits or static shots). -
medium: balanced motion, ideal for everyday scenes. -
large: dramatic, cinematic camera or subject motion. -
duration — select video length:
-
5: short clips, ideal for previews or teasers. -
8: extended motion for storytelling or scene development. -
seed — use a fixed number for reproducibility or leave empty for random generation.
💰 Pricing
| Resolution | Duration | Cost per Clip |
|---|---|---|
| 720p | 5s | $0.60 |
| 720p | 8s | $0.60 |
🚀 How to Use
- ✍️ Write your prompt describing the scene or story.
2.3. ⏱️ Select duration (
5or8seconds). - 🎲 Optionally set a seed for reproducibility.
- ▶️ Click Run to generate your cinematic video.
💡 Pro Tips
- Keep prompts concise but descriptive — include subject, setting, and atmosphere.
- Choose 8s duration for narrative continuity or action sequences.
- Experiment with different seeds to explore creative variations.
